Information about colon cancer symptoms

It is not always the case that symptoms will be seen by people suffering from colon cancer. When colon cancer symptoms do occur they are typically related to changes in the bowels. This generally manifests itself as constipation or diarrhoea. Things to be in particularly on the look out for include narrow stools, bloody stools, cramps and pain in the abdomen. Itching and pain in the anal region are often associated symptoms of anal cancer. Other signs of colorectal cancer include fatigue, loss of appetite and weight loss. Many of the symptoms given above may also be associated with other conditions such as haemorrhoids for example.

Early symptoms of colon cancer

Polyps that grow in the intestinal regions may develop into cancer without any recognisable symptoms until the tumour has reached an advanced stage. It is therefore highly recommended that regular screening for the cancer is taken. Screenings include the digital rectal examination, colonoscopy, x-ray barium enema, and faecal occult blood tests. More details of these tests can be found in the screening section of the colon cancer guide website.

Later Symptoms of colon cancer

The symptoms mentioned above such as changes in bowel movements and bleeding in the stools are typically noticeable when the colorectal cancer has advanced. As people vary tremendously in their bowel habits, you should be looking out for a change in the rate of your bowel patterns. Of course dietary patterns also play a big role in bowel fluctuations, if you have started a diet rich in dietary fibre, or the opposite, similar changes in patterns of bowel movements may also occur.

Blood in the stools is a common symptom of colon cancer, if you observe blood in the toilet bowl or as streaks in your faeces you should consult your doctor; he/she may also perform an occult blood test on the stool to detect hidden blood.

Symptoms may enable the location of the colorectal cancer to be ascertained.

As different symptoms are associated with different areas of the colon, it may be possible to locate the cancer. If cancer occurs on the descending colon it often grows around the diameter of the organ, leading to obstruction of the faeces passage (and changes in bowel patterns) and blood streaks in the faeces. If the cancer is present in the ascending part of the colon it is likely to have symptoms such as discomfort on the right side of the abdomen, anaemia and rectal bleeding. Cancer tumours located in the rectum often lead to blood being seen in the toilet.
