Colorectal Cancer (Bowel Cancer)
Early Onset Colorectal Cancer
The most common symptoms described in early-onset CRC are:
- Abdominal pain
- Rectal bleeding
- Weight loss
- Change in bowel habits.
Most patients with early-onset CRC present with symptoms when compared with patients with late-onset colorectal cancer, that are three times more likely to be diagnosed, incidentally.1 Studies have found that patients with early-onset CRC experience symptoms for a longer duration of time (243 vs 154 days) and have a longer delay from symptom onset to diagnosis (152–217 vs 29.5–87 days).2
