Step 1
Identify risk factors for breast cancer
Answer
Studies have identified several risk factors that increase the likelihood of developing breast cancer. One significant risk factor is a high-fat diet, which has consistently been linked to an increased risk. Additionally, obesity is a crucial factor, as excess body fat can influence hormone levels and contribute to greater risk. Another important aspect is the timing of menstruation; early onset can have implications on hormonal exposure that may elevate breast cancer risk.
Step 2
Evaluate each option
Answer
Now, let's evaluate each of the options:
- Option A: High-fat diet, obesity, and early onset of menstruation. This option includes three known risk factors, making it a strong contender.
- Option B: Early onset of menopause, obesity, and early onset of menstruation. While obesity is a risk factor, early onset of menopause generally decreases the risk making this option less favorable.
- Option C: Early onset of menopause, tobacco smoking, and late onset of menstruation. Tobacco smoking does have some association with various cancers, but late onset of menstruation does not align with increased risk.
- Option D: High-fat diet, tobacco smoking, and late onset of menstruation. This combines a known risk factor (high-fat diet) but pairs it with tobacco smoking and late onset, which does not contribute positively to breast cancer risk.
Thus, the most suitable choice is Option A.
