Which disease is linked to an increased risk of breast and ovarian cancer in women?

• A. BRCA1 mutation
• B. Endometriosis
• C. Fibrocystic breast condition
• D. Uterine fibroids

Answer: (A)

The disease that is linked to an increased risk of breast and ovarian cancer in women is a BRCA1 mutation. The BRCA1 gene is one of the two major genes (alongside BRCA2) that, when mutated, significantly elevate a woman’s lifetime risk of developing breast and ovarian cancer. Women with a BRCA1 mutation have a 55-65% risk of developing breast cancer and about a 39% risk for ovarian cancer by the age of 70, indicating a profound impact of this genetic alteration on cancer susceptibility.

In contrast, endometriosis, while it can lead to various complications and has been studied in relation to cancer risk, does not have the same strong direct correlation with breast and ovarian cancer as BRCA1 mutations do. Similarly, fibrocystic breast condition and uterine fibroids are benign conditions and do not significantly increase the risk of breast or ovarian cancers. Thus, the focus on BRCA1 mutations underscores the importance of genetic factors in understanding and evaluating cancer risks in women.
