Radiation treatment for Hodgkin’s increases breast cancer risk
Radiation “therapy” has been criticized for being everything from
unpredictable to barbaric. A new study, published in The Journal of the
American Medical Association (JAMA) gives critics even more reason to
oppose the procedure.
The
study found that young women with Hodgkin’s disease (HD) who had been
treated with chest radiation have an increased risk of breast cancer. The
risk is so great, that it is the leading cause of death in long-term
survivors of HD, with exceptionally high risks of breast cancer among women
treated at a young age.
Lois B. Travis, M.D., of the National Cancer Institute, National Institutes
of Health, Bethesda, Md., and colleagues analyzed the risk of breast cancer
among 3,817 women diagnosed with HD at age 30 or younger (between June 1965
and December 1994) and concluded that patients “treated” with a radiation
dose of 4 Gy [gray, a measurement of radiation] or more delivered to the
breast has a 3.2-fold increased risk. The risk increased to 8-fold with a
dose of more than 40 Gy. radiation risk. Increased risks persisted for 25 or
more years following radiotherapy, the authors noted.
Despite the obvious increased risks, the researchers were reluctant to
suggest that radiation therapy be eliminated. Instead, they merely called
for “programs of clinician and patient awareness, lifetime surveillance, and
possible prevention strategies.”
