A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes.

Madeleine Nash](https://time.com/author/j-madeleine-nash/) Sep 18, 1996 4:00 AM UTC by [J. Madeleine Nash](https://time.com/author/j-madeleine-nash/) Sep 18, 1996 4:00 AM UTC Deep inside Dustin Fagan’s brain, a cobwebby growth was spreading. Nothing, it seemed, could arrest the malignant tumor’s terrible advance: not surgery, not radiation, not standard chemotherapy. So to save the nine-year-old’s life, his doctors decided to kill him–nearly. They increased the dosage of an anticancer agent known as cyclophosphamide to levels that completely wiped out Dustin’s bone marrow and thus destroyed his ability to generate new red and white blood cells. Then they revived their small patient by injecting him with healthy marrow that had been drawn in advance from his hipbone. The result: today Dustin is 12 and about to enter middle school in Pulaski, Virginia. For almost four years now, he has remained tumor-free. Dustin’s remarkable recovery–from medulloblastoma, one of the deadliest forms of childhood brain cancer–is more than a tribute to the skill of the cancer specialists, or oncologists, who treated him. It is also one of many small but significant mileposts that mark how far medical science has come in its fight against the cluster of diseases collectively known as cancer. The struggle has been long and hard and, unlike work in other medical fields, has produced few really dramatic breakthroughs. But patient by patient, tumor by tumor, doctors are beginning to gain ground. “We may not know how to cure most cancers yet,” says Dr. Richard Klausner, director of the National Cancer Institute (NCI), “but we do know what we need to do to get there. And that’s very exciting.” The cautious optimism that has begun to surface at major cancer-treatment centers is not grounded in any hard calculus. Despite some gains, cancer death rates remain unacceptably high (see chart), and the disease will kill 554,740 people in the U.S. this year. Rather, the optimism stems from an extraordinarily rich epoch of scientific discovery that has revealed the innermost secrets of malignant cells and suggested rational strategies for attacking them. “Until we knew what was wrong with the cancer cell,” says oncologist Dr. Bert Vogelstein of Johns Hopkins University, “we couldn’t even think about ways of targeting treatment.” As doctors come to grips with cancer’s complexity–and discard the dream of discovering a “magic bullet” capable of eradicating the disease forever–a succession of small, incremental improvements shows promise of pushing the death rate down. Already doctors have learned how to keep the disease at bay for months, and sometimes even to produce complete remissions that may last for years. “We’re running a marathon, not a sprint,” observes Dr. Eugenie Kleinerman, a pediatric oncologist at the M.D. Anderson Cancer Center in Houston. “What’s important is not how fast we run the first two miles but when we cross the finish line.” Cancer, scientists now realize, is a genetic disease. It is caused by multiple mutations in the genes that control cell division, the process through which a cell makes a copy of itself by splitting in two. Some of these genes, known as oncogenes, stimulate cell division, while still others, called tumor-suppressor genes, damp it down. In their normal form, both types of genes work together, enabling the body to replace dead cells and repair damaged ones. But mutations in these genes–whether inherited or acquired through environmental insult–very quickly cause a cell to careen out of control, like a car with a stuck accelerator pedal and no brakes. In essence, cancer is an evolutionary drama played out in one part of the body or another–the lung, the breast, the brain. Over time, a single abnormal cell becomes two, then four, then eight, then 16\. Early on, these cells develop a repertoire of “tricks” that confer a survival advantage. Among other things, the tricks ensure that mutation will pile on mutation by shucking off, or silencing, genes that ordinarily monitor replicating DNA for chemical errors. The malignant cells quickly become resistant to the poisons physicians prescribe to kill them. They also acquire the disturbing ability to stimulate the formation of nutrient-bearing blood vessels, thus spurring their own growth. Even if malignant cells grow rather slowly, they grow inexorably, eventually forming a deadly mass that invades surrounding tissue and spreads, or metastasizes, to far-flung locations. Now the stunning laboratory insights into the biological basis of cancer that have accumulated over the past decade are heading into the clinic. Among the cutting-edge strategies that are giving physicians and patients alike reasons for hope: STOPPING THE CELL CYCLE When a cell divides, normally or otherwise, it does so not all at once but in a series of carefully orchestrated steps. Each step provides oncologists with an opportunity to intervene in the process. In order to complete a successful division, for example, a cell must first faithfully copy its DNA. If a cell makes mistakes in this critical task, vigilant enzymes quickly call a halt to the process until repairs can be made. Sometimes, however, the DNA of a dividing cell is too badly damaged to be salvaged. At this point, these same enzymes help activate a kamikaze circuit that compels the cell to commit suicide by destroying its own DNA. Virtually all anticancer drugs interfere with cell division in some fashion. Cyclophosphamide, the compound that finally banished Dustin Fagan’s cancer, belongs to a broad class of drugs that damage the DNA molecule by plastering it with sticky cross-links, thus triggering the suicide sequence. By contrast, the taxoids–including taxol, the compound isolated from the bark of the yew tree that was approved by the Food and Drug Administration as a weapon against ovarian cancer in 1992–cause the same suicidal result by deactivating a molecular machine that, just before cell division, separates the DNA in each chromosome into two separate strands. Still other drugs known as topoisomerase-1 inhibitors block a slightly earlier step in the DNA replication process, the uncoiling of the double-stranded DNA molecule. Useful as they are, these drugs share the same serious drawback. Because they target all dividing cells, they also kill off normal tissue in the skin, hair and bone marrow. The next generation of anticancer agents, however, promises to be much more selective. By targeting oncogenes, for example, researchers hope to switch off the signals that prompt cancer cells to divide in the first place. Particularly promising is a class of drugs known as farnesyltransferase inhibitors, which have been shown to shrink tumors while sparing normal tissues. “Oncology is not a profession that inspires optimism,” admits Dr. Allen Oliff, director of cancer research at Merck & Co. “But these days I’m almost Pollyannaish about finding safer, more effective cancer therapies.” TARGETING TOXINS Not so long ago, doctors thought they had finally found that long-awaited magic bullet in the war against cancer. Their great hope bears the impressive name of monoclonal antibodies, which are proteins that bind to–and attack–a particular target, usually another protein known as an antigen. But while natural antibodies go after antigens on the surface of viruses and bacteria, the artificial monoclonal antibodies are constructed to attack antigens that the immune system does not ordinarily recognize as dangerous, such as those displayed by tumor cells. Moreover, these antibodies (dubbed monoclonal because they are identical) can be made even more deadly by loading them with radioactive iodine and other toxins. Infused into a patient’s bloodstream by the millions, they become biological torpedoes that home in on clusters of malignant cells, blasting them with killer rays. Almost overnight, it seemed, cancer could become as curable as strep throat. When that did not happen immediately, many clinicians gave up on monoclonal antibodies–prematurely, it turns out. “Monoclonal antibodies were always a fantastic idea,” says Dr. Mark Kaminski, a University of Michigan oncologist. “But because we didn’t see the results we had hoped for, enthusiasm waned. Now it’s time to start believing again.” One source of the new hope is the experience of Patricia Haut, a former real estate broker from Auburn, Michigan. Eleven years ago, Haut, then 44, was found to have a slowly progressing but often fatal form of B-cell lymphoma, a disease that afflicts the very white blood cells that make antibodies in the first place. Like most patients, she initially responded to chemotherapy. But after each treatment, the cancer recurred. Then three years ago, as her remissions grew ominously shorter, Haut enrolled in an experimental trial of monoclonal-antibody therapy at Michigan. Over the course of five weeks, she received four infusions of antibodies loaded with radioactive iodine. The result? The tumors in her groin, chest and abdomen disappeared, and to this day Haut remains cancer-free. In a recently completed study, 19 out of 21 B-cell lymphoma patients treated at Michigan responded with partial to complete remissions. ROUSING THE IMMUNE SYSTEM When viruses and bacteria invade the body, they are challenged by the white blood cells, which make up the body’s immune system. Vaccines can strengthen the immune system so that it responds even more vigorously. So why can’t physicians induce the immune system–through anticancer vaccines or other interventions–to attack tumors in the same fashion? “The problem,” says Dr. Frank Hsu of Stanford University, “is that in attacking tumors, we’re trying to kill cells that are derived from normal cells in our own bodies. That’s just a lot harder than killing bacteria or a virus.” But not, Hsu believes, impossible. Early this year, a hint of progress came from a small clinical trial conducted by Hsu and his colleagues. First the researchers extracted specialized white blood cells–so-called dendritic cells–from patients with B-cell lymphoma. They “vaccinated” these cells by bathing them in an antigen found on the surface of tumors and then put the cells back into patients’ bodies. The rationale for this elaborate procedure? Dendritic cells gobble up antigens and break them down into smaller fragments. Then, like bullfighters waving red flags, the cells display strips of antigen, inciting other white blood cells to attack and kill tissue bearing that particular biological marker. Of four patients treated with dendritic-cell therapy by Hsu and his colleagues, two experienced complete remissions, while two others had their tumors substantially reduced in size. Yet another strategy for jolting the immune system into action invokes the latent power of a different kind of white blood cell known as a macrophage. Both the lung and the liver, notes M.D. Anderson’s Kleinerman, are favored sites for the spread of cancer. As it turns out, these organs also contain large numbers of macrophages. But although macrophages sometimes attack tumors, they generally do so only after being alerted by a strong stimulus–a protein, say, that signals the presence of invading bacteria. So Kleinerman and her colleagues took a bacterial protein and encapsulated it in fatty particles the size of red blood cells. They then injected these particles into children who had already been treated for bone cancer that had spread to their lungs. Out of a total of 16 patients, says Kleinerman, nearly a third have remained disease-free for the past three to six years. A much larger trial of this promising therapy is now under way. KEEPING TUMORS IN CHECK Physicians have always focused on trying to eliminate cancer from the body. Many researchers, however, believe the time has come to add a strategy of containment. The idea, says Dr. Judah Folkman of Children’s Hospital of Boston and Harvard Medical School, “is to treat cancer as a chronic disease.” Of particular interest to Folkman and others are various compounds that stop or slow the process by which a tumor stimulates its own growth by creating its own blood supply. Indeed, until that process, known as angiogenesis, takes place, a malignant growth may not even be particularly dangerous. It is the nourishing blood vessels formed through angiogenesis, researchers believe, that give cancer cells their scary ability to multiply and spread. So far, scientists know of more than 20 compounds that block angiogenesis, and the results from animal tests are extremely encouraging. An immune-system stimulant called interleukin-12 has demonstrated an uncanny ability to make newly formed capillaries in mice melt away. Another antiangiogenesis compound, angiostatin, discovered by Folkman’s colleague Dr. Michael O’Reilly, makes colon, breast and prostate tumors shrink in mice. The rodents were given angiostatin for more than 50 days, the equivalent of five years for humans, and their tumors stayed small as long as they took the drug. At present, nine anti-angiogenesis compounds are being tested on human patients. The hope, says Folkman, is that these compounds may be able to slow, or even halt, the growth of tiny cancerous clusters that are missed by radiation and conventional chemotherapy. If that happens, then the lives of patients, even those with widespread disease, might be significantly extended–particularly if more than one agent is used. For instance, the anti-angiogenesis compound TNP-470 appears to have much greater healing power when it is employed in combination with the agent that was used to treat Dustin Fagan, cyclophosphamide. In animal studies conducted at the Dana Farber Cancer Institute, each compound significantly slowed the growth of tumors. But when the two compounds were combined, they produced a complete cure in 42% of the mice. For people with newly diagnosed cancer, this is one of the most exciting, and frustrating, times imaginable. Most patients today are stuck with standard treatment: surgery to remove the primary tumor, followed by radiation or chemotherapy to control metastasis. Yet here too progress is being made. A good example, says Dr. Edison Liu, the new chief of clinical science at nci, is the adoption of higher-dose chemotherapy as the norm for breast-cancer treatment. Doctors have switched not merely because new medicines that combat nausea, anemia and immune suppression have made the side effects more tolerable. They have also made the change because higher doses clearly help women whose tumors resist lower doses of the same drugs. Strikingly, the breast tumors of these patients showed high activity by an oncogene called ERBB2/neu, suggesting cancer genes themselves can be used as a clinical tool. Currently, many women with metastatic breast cancer are opting to undergo a controversial procedure that bombards their bodies with extremely high doses of chemotherapy, then rescues them from certain death with a transplant of stem cells–the forebears of blood cells and platelets–gleaned from their own bone marrow or bloodstream. The trouble is, no one yet knows whether this expensive and risky procedure is worth the effort. While some patients–Dustin Fagan among them–appear to benefit from such aggressive treatments, others do not. The difference between patients who benefit and those who do not, many researchers now suspect, probably lies in the pattern of genetic mutation that characterizes their tumors. In the past, observes NCI director Klausner, physicians classified cancers by the organs they affected: brain cancer, breast cancer, liver cancer, prostate cancer. But these old-fashioned divisions are proving to be misleading. “Cancers should not be lumped together according to where they come from,” declares Klausner, “but according to what they are.” Because they are genetically unstable, many cancer cells end up jettisoning both copies of the tumor-suppressor gene p53\. Still others contain mutant copies of this gene.The difference, it turns out, is highly important. Cells that have normal p53 genes tend to be exquisitely sensitive to chemotherapy, but those with mutant p53 genes are often extremely resistant. This unexpected insight into p53’s clinical role is already inspiring researchers to search out new therapies. Researchers at NCI, for example, are combing through a computer database that contains the chemical profiles of some 350,000 potential anticancer compounds. To date they have identified 112 candidates that may work against cancers with mutant p53 genes. At the same time, researchers in Vogelstein’s lab at Johns Hopkins have come up with a blueprint for a “gene bomb” that selectively kills cells containing altered versions of p53\. The bomb consists of a bacterial gene that converts a normally harmless substance into a toxic poison, but it is activated only by cells in which p53 has undergone significant mutation. In laboratory cultures, at least, the results look better than good. “It really is like a bomb,” marvels Vogelstein. “It kills not only the cell in which it’s activated but surrounding cells as well.” Will the gene bomb work similar magic for patients? Over the coming decade, many experimental anticancer agents that look so promising today will be discarded. Some will prove ineffective, others too toxic. But a select few will begin to make their way into clinical practice, not to substitute for conventional therapy, oncologists say, but to augment it. Every additional treatment, observes Duke University’s Dr. Henry Friedman, the oncologist who treated Dustin Fagan, makes curing cancer more likely. By adding new therapeutic agents to the current mix, he observes, clinicians may be able to eliminate tiny clusters of cancer cells that would otherwise later rebound to kill their patients. This year, for example, medical researchers are conducting a large clinical trial of a promising new vaccine against melanoma, the deadliest form of skin cancer. It will be judged not by its ability to shrink large tumors but by its success in prolonging survival among patients who have already received standard treatment. What is the point of piling one treatment on top of another? Where cancer is concerned, as clinicians well know, one plus one often adds up to much more than two. Earlier this year, oncologists from the U.S. and Canada reported that adding chemotherapy to radiation significantly helped patients with advanced cancer of the nose and throat. Three years after treatment, an impressive 65% of patients who received the combination therapy were still alive, vs. only 24% of those who received radiation alone. Similarly, immune-system stimulants like the interferons and interleukins appear to increase their tumor-fighting power when used together. Twice as many patients with metastatic kidney cancer, a French team reported last May, experienced a notable shrinkage of their tumors when interferon and interleukin were combined as when either agent was used alone. In coming years, doctors hope to be able to combine therapeutic agents in increasingly effective ways. “There will never be a single cure for cancer,” emphasizes the nci’s Klausner–and, in fact, many oncologists believe physicians should start focusing not just on curing cancer but also on ways of controlling it. Ideally, of course, doctors should not be treating cancer but dealing with the conditions that lead to it, such as premalignant polyps and lesions. Even full-blown cancer no longer need look hopeless. If physicians can figure out ways of stopping a primary tumor from spreading, or of preventing small malignancies from growing large, they may yet work wonders. Cancer patients would still have a serious chronic disease but one that could be controlled–like diabetes, hypertension and atherosclerosis–for 10 years, 20 years, even longer. In the future, a diagnosis of cancer will still invoke dread. But if Klausner and others are on the right track, it will seem less and less like an automatic death sentence. –With reporting by Hannah Bloch/Washington ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6729601/the-enemy-within-7/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6729601/the-enemy-within-7/"},"headline":"THE ENEMY WITHIN (18 Sep 1996)","datePublished":"1996-09-18T04:00:00.000Z","dateModified":"2026-03-21T03:25:57.663Z","description":"THOUGH NO MAGIC BULLET IS AT HAND, CANCER IS GRADUALLY SUCCUMBING TO A SLOW BUT STEADY DOSE OF STRATEGIES","url":"https://time.com/archive/6729601/the-enemy-within-7/","keywords":[],"thumbnailUrl":"","author":[{"@type":"Person","name":"J.
