Colorectal CancerColorectal Cancer is a malignant tumor that first appears in the colon or rectum. These cancers start in the inner lining of the bowel wall or mucosa. They spread through the wall to surrounding tissue or to the adjacent lymph nodes or nodes in the abdomen. The cancer cells can also travel to distant parts of the body (metastasize).
Known risk factors include:
Symptoms associated with colorectal cancer:
Investigation usually includes: a full physical examination with digital rectal examination, stool test for occult blood and colonoscopy (or barium enema).
Colonoscopy for Screening for Colorectal Cancer is recommended for: patients over 50 years old, with no symptoms or risk factors; patients over 40 years old who have a cole relative with colorectal cancer or adenomatous polyps, very strong family history of colorectal cancer - HNPCCor FAP,personal history of colonic polyps or inflammatory bowel disease.
The primary therapy for colorectal cancer is surgery. During the operation the section of the bowel that contains the cancer is removed, along with the lymph nodes that drain that area.
In the majority of the cases we recommend Laparoscopic Colectomy for the treatment of colorectal cancer.
Usually, at an early stage colorectal cancer is curable by surgery. If metastases to the lymph nodes are found - chemotherapy is usually recomended. In case of rectal cancer chemotherapy and radiotherapy, both, are usually required.
If metastases to the liver occur, depending on the size and location, they can be treated by surgical removal or cryosurgery(freezing of the cancer cells).
