Prostate Cancer in the Family Tree Increases A Woman's Risk of Breast Cancer

A study, published in the journal Cancer, found that women with a family history of both breast and prostate cancer among first-degree relatives have an almost 2-fold increase in risk of developing breast cancer themselves.


Having a family history of prostate cancer among first-degree relatives may increase a woman's risk of developing breast cancer. That is the conclusion of a new study published early online in , a peer-reviewed journal of the American Cancer Society. The study's results indicate that clinicians should take a complete family history of all cancers--even those in family members of the opposite sex--to help assess a patient's risk of developing cancer.

Evidence suggests that the risk of developing breast and prostate cancer is increased among individuals with a family history of the same disease, particularly among first-degree relatives. However, less is known about the relationship between breast and prostate cancer within families.
