How can you tell if you have colon cancer?

Answer 1

Symptoms of colon cancer can include blood in the stool, change in bowel habits, and discomfort in the abdominal region. It is best to see a doctor to diagnose the issue because colon cancer can be deadly.

Answer 2

In the early stages of Colon Cancer, there are commonly no symptoms. So if you are above the age of 50 you need to be tested for Colon Cancer so if you do have it you can catch it early.

Some symptoms may include:

• Diarrhea and/or Constipation
• Abdominal or "Gas" Pains
• Having either more or less frequent bowel movements.
• Less hungry (Appetite)
• Weight Loss
• Nausea/General Sickness symptoms
• Constantly Tired for no reason

Answer 3

The symptoms of colorectal cancer depend on the location of tumor in the bowel, and whether it has spread elsewhere in the body (metastasis). Most of the symptoms may occur in other diseases as well, and hence none of the symptoms mentioned here is diagnostic of colorectal cancer. Symptoms and signs are divided into local, constitutional (affecting the whole body) and metastatic (caused by spread to other organs).

Local

Local symptoms are more likely if the tumor is located closer to the anus. There may be a change in bowel habit (new-onset constipation or diarrhea in the absence of another cause), and a feeling of incomplete defecation (rectal tenesmus) . Lower gastrointestinal bleeding, including the passage of bright red blood in the stool, may indicate colorectal cancer, as may the increased presence ofmucus. Melena, black stool with a tarry appearance, normally occurs in upper gastrointestinal bleeding (such as from a duodenal ulcer), but is sometimes encountered in colorectal cancer when the disease is located in the beginning of the large bowel.

A tumor that is large enough to fill the entire lumen of the bowel may cause bowel obstruction. This situation is characterized by constipation, abdominal pain, abdominal distension and vomiting. This occasionally leads to the obstructed and distended bowel perforating and causing peritonitis. A large left colonic tumor may compress the left ureter and cause hydronephrosis.

Certain local effects of colorectal cancer occur when the disease has become more advanced. A large tumor is more likely to be noticed on feeling the abdomen, and it may be noticed by a doctor on physical examination. The disease may invade other organs, and may cause blood or air in the urine (invasion of the bladder) or vaginal discharge (invasion of the female reproductive tract). If a tumor has caused chronic occult bleeding, iron deficiency anemia may occur; this may be experienced as fatigue, palpitations and noticed as pallor (pale appearance of the skin). Colorectal cancer may also lead to weight loss, generally due to a decreased appetite.

More unusual constitutional symptoms are an unexplained fever and one of several paraneoplastic syndromes. The most common paraneoplastic syndrome is thrombosis, usually deep vein thrombosis.

Answer 4

Here these are the signs/symptoms of colon cancer.

Abdominal pain.

Unwanted sudden weight loss.

Blood in your stools or bleeding from rectum.

A change to your normal bowel habits that persists for more than three weeks like diarrhea, constipation or passing stools more frequently than usual.

Weakness of fatigue.

Sometimes early colon cancer may have no symptoms and some symptoms of later colon cancer can also occur in people with less serious medical problems, such as hemorrhoids (piles).
