Symptoms And Treatment Of Patients With Colon Cancer

Interventional Therapy Nearly one-third of patients diagnosed with colon cancer have metastatic disease (disease that has spread to other parts of the body) (Colon Cancer Alliance 2015a). The most common site of spread is the liver (Colon Cancer Alliance 2015a). Patients with rectal cancer may also have metastatic disease that has spread to the liver. Ablation and embolization are interventional therapies directed at the liver to destroy cancer cells. Ablation This technique destroys tumors without removing them. There are several types of ablation, including: †¢ Radiofrequency ablation: This technique uses heat to destroy cancer cells. The physician guides a probe containing tiny electrodes through the skin into the tumor using imaging techniques, such as CT, MRI, or ultrasound. The heat generated by the electrodes destroys the cancer cells. Generally, only a local anesthetic is required for this procedure. In some cases, the physician may insert the probe through a cut in the abdomen using a laparoscope. This procedure requires general anesthesia. †¢ Cryosurgery: The opposite of radiofrequency ablation, cryosurgery (also called cryoablation or cryotherapy) uses extreme cold to destroy cancer cells. †¢ Ethanol ablation: Ethanol ablation uses concentrated alcohol to destroy cancer cells. The alcohol is injected directly into the tumor. Serious complications resulting from ablations are rare. Potential risks and side effects include abdominal pain, bleeding in the chest orShow MoreRelatedColorectal Cancer : Cancer And Cancer1140 Words   |  5 PagesColorectal cancer, also called colon cancer, is a disease in which cancer cells form in the colon, which is the upper five to six feet of the large bowel, or large intestine.

The large intestine is divided into the long colon and a short rectum, just before the anus. Two thirds of bowel cancers occur in the colon and one third in the rectum, with very few in the small intestine. Who is at risk of bowel cancer?

Using figures from 2015, that would be 3,981 new colorectal diagnoses related to Lynch syndrome.
