Effects of Breast Radiation on the Heart

Breast cancer is one of the most common types of cancer in women. It is characterized by a lump in a breast. It might be treated by removing the lump or one, or both, of the breasts and then using radiation to kill any remaining cancer cells. This can cause risks to the heart.

Breast Cancer

According to the Radiology Info website, an estimated 240,000 U.S. women were diagnosed with breast cancer in 2008. Most diagnosed with cancer choose to keep their breasts, if possible.

Radiation

Using radiation reduces the risk of the cancer returning after it is surgically removed. This allows more women to choose to not have their breasts removed.

Risk to the Heart

Radiation to the breasts does reach the heart as well, especially when applied to the left breast. In a University of Michigan study of women who had radiation done on their left breast about 12 years earlier, 59 percent developed heart abnormalities.

Increased Risk Factors

According to Radiology Info, it is not known if women who smoke or have pre-existing heart conditions may be more affected by radiation to the heart, but it is likely that the effects are small.

Prevention

According to Dr. Candace R. Correa, who did the study at Michigan, the benefits of radiation outweigh the risks. You still need to maintain a lifestyle beneficial for the heart and get regular checkups on your heart.
