Answer:
d) 74 years
Explanation:
Women should start breast cancer screening mammography from the age of 40. If the patient does not start at this age, she should be at 50. The decision on when to start screening should be made based on the benefits and potential harm.
Screening should continue until at least 74 years. After that, the decision to discontinue or not should be made taking into account the patient's current health and life expectancy.
