Breast Cancer Radiation Slightly Raises Heart Disease Risk

Breast Cancer Radiation Slightly Raises Heart Disease Risk | Heart and Vascular Health | Scoop.it

Radiation treatments for breast cancer may increase the risk for heart disease later in life, a new study suggests.

In the study, the higher the level of radiation to the chest, the greater a women's risk of ischemic hw=eart disease was within five years after therapy, the researchers said. Ischemic heart diseaseinvolves reduced blood supply to the heart. This increased risk continued for decades after the treatment

Seth Bilazarian, MD's insight:

The risk is small.  Increased risk of about 0.5%.

 

For instance, for a 50-year-old women with no previous risk factors for heart disease, who received a radiation dose of 3 gray (Gy), her risk of dying from heart disease would increase just 0.5 % & her risk of experiencing an event like a heart attack would increase just 1%, over the next 30 years.

Radiation Safety in Heart Imaging Tests

My comment: Useful information for patients undergoing cardiac testing.  The 10 questions are excessive.  Patients should be sure they understand the answers to questions 1,2 4 & 9.

===========================

Recent public concern regarding radiation exposure in a cardiac test provides an important opportunity for all patients to discuss with their doctors the benefits and risk of testing. Within the medical community, there is controversy regarding the projected cancer risk resulting from radiation exposure during cardiac testing, such as a nuclear scan or catheterization. Research experts studying the projected cancer risk agree that there is a very low risk of cancer following radiation exposure during medical testing for certain procedures including a nuclear scan or catheterization.
