In brief: Often "silent"

Unfortunately, colon cancers may develop "under the radar" for quite some time before symptoms occur. The earliest sign is usually anemia caused by a slowly bleeding tumor. As the cancer grows, it may block the colon causing cramping pain, bloating, and/or pencil-thin stools.
The gold standard for diagnosing colorectal cancer is screening colonoscopy at age 50, or earlier with a family history.

In brief: Colorectal cancer

There are classic symptoms of decreased caliber of stool and constipation or change in bowel habits.
But it can also present as a rectal bleed and weight loss.
