Radiation Therapy Linked to Secondary Cancers?? KBOI News, 7 March 12,?(NEW YORK)???While the number of cancer survivors has tripled since the 1970s and continues to grow, the cost of that survival for many has been the development of secondary cancers and cardiovascular disease related to radiation treatment, according to an upcoming report by a scientific committee.?
The committee, convened by the National Council on Radiation Protection and Measurements, met over a period of five years to consider some of the most serious repercussions of radiation therapy and make recommendations to more comprehensively assess the risks related to treatment. They plan to issue a comprehensive report of their findings, and have also published commentary in the?Journal of the National Cancer Institute.?
?For many survivors, the cost of the cure of their cancer has been late, life-threatening effects of therapy,? said Dr. Lois B. Travis, director of the Rubin Center for Cancer Survivorship at the James P. Wilmot Cancer Center at the University of Rochester Medical Center. ?We recognized that secondary malignant neoplasms and cardiovascular disease are among the most serious adverse effects experienced by the growing number of survivors worldwide.?
The development of these serious problems, she explained, are due to a combination of radiation therapy chemotherapy and other factors, including age, the environment, lifestyle habits and genetics.
Younger patients are especially susceptible to the effects of radiation, and the three cancers that have been most strongly associated with radiation are breast cancer, thyroid cancer and bone marrow cancers, including leukemia. Cardiovascular disease related to radiation therapy is most often associated with treatment for breast cancer and Hodgkin lymphoma, since radiation is applied to the chest.
While the committee focused its attention on radiation therapy, chemotherapy also carries the potential for life-threatening effects.??With certain types of chemotherapy, there?s an increased risk for developing leukemias,? said Dr. Otis Brawley, medical director of the American Cancer Society.
Cole Whiting, just 10 years old, is now living with leukemia after beating another cancer, rhabdomyosarcoma of the sinuses, a few years back.
Shortly after completing 15 months of radiation treatment and chemotherapy for rhabdomyosarcoma, his family got word he developed yet another cancer ? acute myeloid leukemia.
?He was two weeks shy of finishing kindergarten when he got diagnosed. It was a result of the treatment he got for the first cancer,? said his mother, Madonna Whiting. ?It was even worse the second time, because we knew what we were in for having gone through it already.???
Childhood radiation may also have other effects later on, including fertility problems, stunted growth and cognitive deficits.?Clinicians say the benefits of radiation treatment for many types of cancer far outweigh the potential risks of experiencing serious adverse effects years later, and say radiation is now a lot safer than it once was.??.??We try to use radiation as sparingly as possible, but unfortunately, it is frequently part of the cure in a lot of cancers and it?s absolutely necessary,? ?. ?http://www.670kboi.com/rssItem.asp?feedid=116&itemid=29811361
