Symptoms are common and prominent late in colon cancer when the prognosis is poor but are less common and less obvious early in the disease. The classic warning signs include loss of appetite, loss of weight, worsening constipation, alternating bowel habits, blood in the stool, decrease in stool caliber, and nausea or vomiting. Treatment options for colon cancer depend on the stage of the tumor that is, how far it has spread or how deeply it is affecting the intestinal wall and other tissues. In general, patients with colon cancer receive post-operative chemotherapy if the lymph nodes are positive. Treatment is also determined by the patient's age, medical history, overall health, and tolerance for specific medications and therapies. Surgery is the only curative modality for localized colon cancer (stage I-III) and potentially provides the only curative option for patients with limited metastatic disease in liver and/or lung (stage IV disease). The general principles for all operations include removal of the primary tumor with adequate margins including areas of vascular and lymphatic drainage. An open colectomy is the most common surgical procedure employed when treating colon cancers. The surgery is performed through a laparotomy incision where a part of the colon with the cancer and a small segment of normal colon on either side of the cancer are removed. Laparoscopic lobectomy is minimally invasive technique is an approach to resect a part of the colon and nearby lymph nodes and may be an option for some earlier stage cancers. Instead of making one long incision in the abdomen, the surgeon makes several smaller incisions.
