Radiation Treatment in Childhood Boosts Breast Cancer Risk

Options

"Among the childhood cancer survivors, 24 percent were diagnosed with breast cancer by the time they were 50 years old. In addition, 30 percent who survived Hodgkin lymphoma developed breast cancer.

In comparison, the researchers noted that among women with the BRCA1 gene mutation - usually considered at high risk for breast cancer - 31 percent developed breast cancer by age 50.

Experts once thought that only moderate to high doses of radiation raised the risk for breast cancer, but this study shows that even those who got low doses face an increased risk."
