Screening procedures for colorectal cancer

Another helpful method in the diagnosis of colorectal cancer is the chair or stool guaiac test occult blood test to detect the doctor, blood in stool, which is invisible to the naked eye, can help. You should have one years after the age of 50 years.

The results of this test will determine whether you need other screening procedures for colorectal cancer as proctosigmoidoscopy and colonoscopy. What are these tongue twisters?

In the former, the doctor uses a flexible,lighted tube called proctosigmoidoscope found on the lower part of the colon and rectum to examine - the area where the cancers tend to be. This should first be made between the ages of 45 and every two years thereafter, depending on your condition. For those with a family history of disease, more frequent examinations are required.

"Nearly 50 percent of all colorectal cancer or polyps may be seen during such an inspection. In addition, diagnosis of other diseases such as Crohn's disease orUlcerative colitis can be made with this instrument. Samples of tissue can be taken by the instrument for later examination under a microscope (biopsy), "said Dr. David E. Larson, editor-in-Chief of the" Mayo Clinic Family Health Book. "

Colonoscopy, on the other hand, examines the entire colon with a somewhat similar instrument called the fiber-optic endoscope. This gives a clear overview of the lining of the colon from the anus to the cecum (the beginning of the colonlocated in the lower right part of the abdomen).

The endoscope allows the physician to remove polyps, and for a cause of chronic or acute bleeding, when other attempts have failed to seek to do so.

Can be conducted in about half of cases, surgery to cure colon cancer. How big this is depends on the location and size of the cancer. The surgeon can remove the cancer and once again healthy parts of the rectum, so the patient can function normally. Or he can remove theentire rectum and create an artificial opening called a stoma on the abdomen for stool to pass. This occurs in about 20 percent of cases.

Additional treatments in the form of chemotherapy and radiation to follow. For cancer that has spread to the lungs, little can be done.

"In summary, it must be, remember, the key to the cure of colorectal cancer is early detection and immediate removal of polyps or tumors. Follow-up chemotherapy and immunotherapy, although malignancyseems to have been completely cut out, have also shown to be effective, "concluded Dr. Isadore Rosenfeld of the New York Hospital - Memorial Sloan-Kettering Cancer Center," is the best treatment.
