What is considered a primary risk factor for breast cancer?

• A. Age of first menstrual cycle
• B. Family history of breast cancer
• C. Dietary habits
• D. Previous breast surgeries

Answer: (B)

A family history of breast cancer is recognized as a primary risk factor due to the significant genetic predisposition associated with the disease. Women who have close relatives—such as mothers, sisters, or daughters—diagnosed with breast cancer are at a higher risk due to inherited mutations in the BRCA1 and BRCA2 genes, which are linked to increased susceptibility to breast and ovarian cancer. This hereditary component underscores the importance of family history in assessing risk and guiding screening practices and preventive measures. While the age of first menstrual cycle, dietary habits, and previous breast surgeries can contribute to the overall risk profile, they do not carry the same weight as having a family history of breast cancer. The genetic implications of family history make it a crucial factor in understanding individual risk and shaping monitoring protocols for early detection in those with a familial link to the disease.
