Question

which woman would be most likely to benefit from genetic testing for breast cancer?
o a 25-year-old woman whose mother, aunt, and grandmother had breast cancer
a healthy 75-year-old woman with no family history of breast cancer
a 40-year-old woman who has a cousin with breast cancer
o all women can benefit from genetic testing for breast cancer.
o a 55-year-old woman whose older sister was just diagnosed with breast cancer

Explanation:

Genetic testing for breast cancer is most beneficial for those with a strong family history of the disease. A 25 - year - old woman with multiple close relatives (mother, aunt, grandmother) having breast cancer has a higher risk due to possible inherited genetic mutations (like BRCA1/BRCA2). A 75 - year - old with no family history has low risk. A cousin is a more distant relative compared to mother, aunt, etc. Saying all women can benefit is an over - generalization. A sister is a closer relative than a cousin, but the 25 - year - old's multiple close relatives make her a higher priority.

Answer:

a 25 - year - old woman whose mother, aunt, and grandmother had breast cancer
