If abnormal growth of the cells in the colon or rectum takes the shape of a tumor, the disease is called colorectal cancer. The cancerous cells start affecting the inner layer of tissues in either the colon or the rectum and then spread to other layers. More deep these layers affected, more advanced is the stage of cancer in patient’s body.
Colorectal cancer is cancer of the colon or rectum. It is similarly common in men and women. An expected 146,970 people will be diagnosed in 2009, and an expected 49,920 people will die from the disease. With suggested screening, this cancer can be prohibited (by removing polyps before they become cancerous) or detect early, when it can be extra easily and successfully treated.

Early stages of colorectal cancer do not usually have symptoms. Advanced disease may cause:
Surgery is the most general treatment, When the cancer has increase, chemotherapy or radiation therapy is prearranged before or after surgery.
If you be at average risk for colorectal cancer, start having normal screening at age 50. If you are at better risk, you may need to start regular screening at an previous age. The most excellent time to get screened is before any symptoms come into view. Use this guide to assist you discuss screening option with your health care specialized. Consider one of the following:
Screening intervals for tests that find pre-cancer and cancer:
Screening intervals for tests that mainly find cancer:
Any abnormal effect of a virtual colonoscopy or double-contrast barium enema, as fine as a positive FOBT, FIT or sDNA test, should be follow up with a colonoscopy.
The following are the tests done to detect colorectal cancer:
There are two types of FOBT conducted by health providers.
According to studies, if FOBT will be conducted in every 1 or 2 years in people of ages 50 to 80, death toll due to colorectal cancer may reduce by 15 to 33 percent.
In this method a lighted device called sigmoidoscope finds the cancerous and pre-cancerous cells in the rectum and lower colon. During this test the affected cells can be found and they can be removed or biopsied. A cleaned lower colon is required for this method.
In this method of detecting colorectal cancer, a lighted instrument known as colonoscope is used. The rectum and both the upper and lower colon are examined to find affected cells. The cancerous cells can be removed or biopsied. Patient may receive some sedation and the entire colon is cleaned before undergoing this test.
In this method of detecting colorectal cancer, photos of colon and rectum are produced by using special x-ray instrument. The computer brings the pictures together and images are checked for polyps and other anomalies. Sedation is not required for this test but thorough cleansing of colon is a must for this test.
In this method of detecting colorectal cancer the patient is given an enema with a barium solution and air has to be introduced into the colon. Then a sequence of x-rays is taken to detect cancer as barium and air united to delineate the colon and rectum.
The following are some of the preventive measure to reduce the risk of colorectal cancer:
As per survey reports, the treatment cost of colorectal cancer at an early stage may be approximately $30,000 per patient. Similarly, a patient may have to spend as much as $120,000 towards the treatment cost of colorectal cancer at the late stage. However, the mode of treatment varies from one case to another and the cost may also differ.
The side effects of colorectal cancer treatment are temporary and being mentally prepared to handle these is half the battle. The following are some of the side effects of different procedures of colorectal cancer treatment:
