At what age should colon cancer screening begin for women?

• A. 45
• B. 50
• C. 40
• D. 55

Answer: (A)

Colorectal cancer screening for average-risk adults should begin at age 45. This change from 50 reflects evidence that more cancers are appearing in people in their 40s, so starting earlier improves the chances of detecting precancerous polyps or cancer at a stage when treatment is more effective. For women, the same starting age applies. If there are higher-risk factors (like a family history or certain genetic conditions), screening may start earlier and occur more often. The other ages aren’t the recommended starting points for average-risk individuals.
