In brief: No symptoms
Unfortunately early colon and rectal cancer will present with no symptoms.
This is why it is important to be screened at an appropriate e age. This typically begins at 50 yrs for normal risk individuals. Rectal bleeding can be a sign which is why this should be evaluated by your doctor if present.

In brief: None!
Early symptoms of colon and rectal cancer do not exist.
That is why screening tests are so important. Simple tests such as checking for blood in the stool can hep identify people at risk for colorectal cancer. Colonoscopy is the gold standard for screening in the usa. Symptoms that may be caused by colorectal cancer include diarrhea, constipation, change in bowel habits and bleeding.

In brief: Usually none.
The most common symptom in people diagnosed with colorectal cancer is no symptom at all; this is why screening is so important.
Most common symptoms are change in bowel habits, weight loss, blood with stools, anemia- but these are late symptoms, and are associated with a poor outcome. Every american should be screened at age 50, sooner if a first-degree relative has had cr cancer or polyps.

In brief: None or bleeding
Most colon and rectal cancers have no symptoms until they either start bleeding (causing anemia - a low blood level), rupture open (perforate), or invade other tissues, causing pain.
This is why screening colonoscopy -- to find cancers while they are small, and to remove polyps which grow up to become cancers -- is so important. Go get checked!
