What are the different stages of colon cancer


What are the different stages of colon cancer?
My dad had a portion of his colon removed. The doctor said he's 98% sure it's cancer and they're going to see whether it's reached stage 3 or not. Do you think if it's reached stage 4 they would have known already? He's had a CT scan before his surgery...would it have been detected from that??

He would have known if it was stage 4 from the CT and he would have checked for liver mets during the surgery. So yes from both of these things he would know if it was a stage 4. What is it that you are not understanding?
2 :
YES. If it is stage 3 or 4 cancer he would definetely known about it early. Even in the CT also it will be shown clearly. Anyway, you doctor is the best judge and he will do the needful. I am giving below the details of different stages of Colon cancer just for your information - People who have inflammatory bowel disease (IBD) are at an increased risk of developing colon cancer. While colon cancer is among the most preventable of cancers, it is often not diagnosed until symptoms become apparent or bothersome. By that time, the colon cancer may be in a more advanced stage. Colorectal cancer has four distinct stages, along with a fifth stage that is called 'recurring'. Each stage has different treatment options and five-year survival rate. Stage 0 This is the earliest stage of colorectal cancer. The cancer only involves the lining, or mucosa, of the colon or rectum and is confined to polyp(s) (tissue bulging from the surface of an organ). When the polyps are removed during a colonoscopy (a procedure known as a polypectomy), the chance of them progressing to later stages of cancer is eliminated. Stage I Stage I colon cancer involves more than just the inner lining of the colon. The polyp has progressed to a tumor, and extends into the wall of the colon or rectum. Treatment can include surgery to remove the section of the colon that is cancerous. This type of surgery is called a resection. The healthy, non-cancerous sections of the colon are reconnected again. The five-year survival rate is 95 percent. Stage II Stage II colorectal cancer is when the cancer has spread beyond the colon to the tissue that surrounds the colon but has not spread to lymph nodes. Cancer spreading in this manner from one part of the body to another is called metastasis. A resection surgery may also be used to treat this stage of cancer. The five-year survival rate drops dramatically to 60 percent. Stage III Cancer that has spread outside the colon and on to the lymph nodes in the area surrounding the colon is known as Stage III. In this stage, the cancer has not spread to other organs in the body, and treatment is more aggressive. Surgical resection of the colon, chemotherapy, and other medical therapies may be necessary. The five-year survival rate is 35 to 60 percent. Stage IV In this stage, the cancer had spread to other organs in the body such as the lungs or liver. In addition to a surgical resection and chemotherapy, radiation treatment and surgery to remove other affected parts of the body may be necessary. At this stage, there is only a 3 percent chance of reaching the five-year survival time. Recurrent Cancer Cancer that comes back again after treatment, either in the colon, or in some other part of the body, is called recurrent. Even after successful treatment of colon cancer, regular check ups are necessary to catch any recurrent cancer early. In the early stages, colon cancer is one of the most curable cancers. In the later - it is the second most deadly. Colon cancer is the second leading cause of death from cancer in America (lung cancer is the first). Contrary to popular belief, only 15 percent of colon cancer patients must have a permanent colostomy.-
