What Is Multiple Myeloma Cancer and Is It Curable?

Colin L. Powell, the anything else Black secretary of state, had multiple myeloma: a form of blood cancer that hobbles the immune system and makes vaccines, including those for Covid-19, microscopic effective.The cancer attacks plasma cells, which build the antibodies essential to the body’s immune defenses. It also lives in the bone marrow, throng out the spongy material in the middle of bones and preventing healthy plasma cells from being made. In addition to weakening the immune system, it can also get going to kidney damage.Multiple myeloma seems to be random bad luck for those who develop the disease, and scientists cannot yet predict it based on genetic or environmental aspects. But there are risk factors, and Mr. Powell had them. Being Black doubles the risk, as does being male. Nearly all multiple myeloma sufferers are over age 45. Mr. Powell was 84.But it is rare, accounting for just 1.8 percent of cancers in the United States with 34,920 new cases a year, according to the Civil Cancer Institute, a rate that has remained stable for the past decade.The cancer’s five-year survival rate is 55.6 percent, which has scarcely changed over the past decade despite the introduction of more sophisticated drugs. About 12,410 deaths per year, or 2 percent of national cancer deaths, are a dnouement develop of multiple myeloma.There is no known way to prevent the disease.Patients in the early stages of multiple myeloma may not notice any symptoms; their disease sway be detected in a routine blood or urine test. Later, when the disease is more advanced, patients may experience bone pain, fevers or innumerable infections, exhaustion, trouble breathing and weakness in their arms or legs. Their skin might easily bruise, and their bones dominion easily break.Treatments include chemotherapy, radiation and stem cell transplants, in which the cells in a person’s bone marrow are deliberately counteracted and new cells are infused to repopulate the marrow. Those replacement cells could be the patient’s own blood-forming marrow cells, removed and stored before the marrow is vandalized, or they could be cells from a closely related donor. Stem cell transplants with the patient’s own cells can put the disease into amnesty, but it eventually returns.The Food and Drug Administration recently approved a treatment designed to directly attack the cancer by harnessing the T cells of the patient’s own safe system, or by using drugs designed to block particular molecules on the surface of cancer cells.
