Not always: Colon cancer tends to not have any signs or symptoms when it is early (when it is easiest to treat). That is why screening colonoscopies are so important, to remove any polyps that may become cancer, and to directly look for cancers. Colon cancer can cause bleeding from the rectum, tiredness from anemia, stool changes, or abdominal pain. Other things can cause this too. Best to be seen if ?S.

A lot of times none: A lot of times colon cancer has no or minimal symptoms until it reaches a larger size. If causing symptoms they are blood in stool, change in stool caliber or shape, change in bowel habits, anemia, weight loss, abdominal pain and bloating, and some other symptoms. If you are concerned it is better to see a doctor. If the doctor becomes suspicious to colon cancer he will send you for colonoscopy.

Colon cancer: Signs or symptoms can include any of the following, change in your bowel habits, including diarrhea or constipation, change in the consistency of your stool, rectal bleeding or blood in your stool, persistent abdominal pain a feeling that your bowel doesn't empty completely, weakness or fatigue from anemia. Also unintentional significant weight loss can be a sign. See your md if these occur.

True, remember too that often it will have no symptoms so it is very important to follow the age and risk appropriate screenings. Talk to your doc about it.

Varies per person.: Signs and symptoms of colon cancer include: a change in bowel habits (including diarrhea or constipation or a change in the consistency of stool), rectal bleeding or blood in stool, persistent abdominal discomfort (like cramps, gas or pain), a feeling that bowels do not empty completely, weakness / fatigue, and unexplained weight loss. Many people with early colon cancer experience no symptoms.

Very true, thus the importance of getting screening colonoscopies at the proper interval.

Maybe none: First signs may be non-visible rectal bleeding, changes to bowel function. Early colon cancers will have no symptoms. Colonoscopy is a way to find a colon cancer early.

None really...: In the majority of patients (over 80%), colon cancer is silent. Symptoms and signs of altered stool pattern or appearance, weight loss, blood in the stool are often late manifestations of advanced disease. Unfortunately, these signs are nonspecific, and can present with many other GI issues--so don't freak out if you are experiencing them. Just get checked.

They can vary.: In older patients, physicians presume that "rectal bleeding is colon cancer until proven otherwise". Worrisome signs can include pain, diarrhea, constipation, blockage of the intestine, weakness, fatigue, weight loss, and even an enlarging lump that can be felt under the skin. These signs don't necessarily mean that one has colon cancer. The goal is to find colon cancer before any signs appear.
