Which of the following is a common risk factor for breast cancer?

• A. Lack of physical fitness
• B. High-fat diet
• C. Family history of breast cancer
• D. Exposure to sunlight

Answer: (C)

A family history of breast cancer is widely recognized as a significant risk factor for developing the disease. When members of a family have been diagnosed with breast cancer, especially if the cases occurred at an early age or in multiple relatives, this can indicate a genetic predisposition. Certain inherited mutations, such as those in the BRCA1 and BRCA2 genes, increase the likelihood of developing breast cancer and can be passed down through families. Thus, women with a family history of breast cancer should be vigilant about regular screenings and may consider genetic counseling to understand their risks more effectively. Although factors like lack of physical fitness and high-fat diets can contribute to overall health and potentially influence cancer risk, they are not as directly correlated with breast cancer as a family history. Likewise, while exposure to sunlight has its own health implications, it is not associated with an increased risk of breast cancer. Understanding the nuanced role genetics play in cancer risk helps in assessing individual susceptibility and determining appropriate preventive measures.
