رجل عمره ٤٧ سنة صحته جيدة ولا يوجد في عائلته سرطان قولون، يسأل متى يبدأ فحص سرطان القولون. ما الإجابة حسب إرشادات USPSTF الأمريكية الحالية؟

A healthy 47-year-old man with no family history of colon cancer asks when to start colorectal cancer screening. What is the answer under current US (USPSTF) guidance?

1. Now, as screening starts at age 45
2. Only if he sees blood in his stool or a bowel change
3. At 60, because he is at low risk
4. At 50, as was recommended in the past

Answer: A) Now, as screening starts at age 45. Since 2021 the USPSTF has lowered the starting age for average-risk adults to 45 because of rising cases in younger people. Screening is for people without symptoms; waiting for symptoms misses early detection.
