Final answer:
Mammograms should be done yearly starting at 2) 50 years old.
Step-by-step explanation:
Annual mammograms are generally recommended for women aged 50 and older to screen for breast cancer. Mammograms are important because they can help detect breast cancer early, which increases the chances of successful treatment and reduces the risk of death. While mammograms can't diagnose a malignant tumor, they can identify lumps or regions of increased density within the breast that may indicate the presence of cancer.
It's worth noting that guidelines for mammogram screening may vary for individuals with a family history of breast cancer or other risk factors. It's essential for women to consult with their healthcare provider to determine the best screening schedule based on their individual circumstances. Therefore the correct answer is 2) 50 years old
