Stages Of Colon Adenocarcinoma

Stage 0 According to the American Cancer Society, oncologists stage adenocarcinoma of the colon according the TNM classification. T stands for tumor and refers to the size of the primary lesion. N stands for nodes and refers to the number of lymph nodes--small nodules of the immune system that have become involved. Finally, M stands for metastases, and indicates whether the cancer has spread. Stage 0 is defined as Tis N0 M0. This means the tumor is "in situ" or has not spread beyond the innermost layer of the colon, has no lymph node involvement and no metastases.

It is either classified as a T1 N0 M0 or a T2 N0 M0. This means that no lymph nodes have become involved in the cancer and no metastasis has occurred. However, the tumor has grown larger than in stage 0. A T1 tumor has invaded past the innermost tissues of the colon. In T2 it has spread even deeper into the wall, says the American Cancer Society. Stage 2 Stage 2 colon cancer is also divided into substages. recommended site http://www.livestrong.com/article/162178-stages-of-colon-adenocarcinoma/







Staging Colon and Rectal Cancer





It also allows them to determine if the cancer is getting better with treatment or not responding. Staging Colon Cancer Stage 0 Stage 0 cancer of the colon is very early cancer. The cancer is found only in the innermost lining of the colon. Learn more about treatments for stage 0 colon cancer . Stage I The cancer has spread beyond the innermost lining of the colon to the second and third layers and involves the inside wall of the colon. The cancer has not spread to the outer wall of the colon or outside the colon. Learn more about treatments for stage I colon cancer . Stage II The tumor extends through the muscular wall of the colon, but there is no cancer in the lymph nodes (small structures that are found throughout the body that produce and store cells that fight infection). Learn more about treatments for stage II colon cancer . Stage III The cancer has spread outside the colon to one or more lymph nodes (small structures that are found throughout the body that produce and store cells that fight infection). Learn more about treatments for stage III colon cancer . Stage IV The cancer has spread outside the colon to other parts of the body, such as the liver or the lungs. The tumor can be any size and may or may not include affected lymph nodes (small structures that are found throughout the body that produce and store cells that fight infection). Learn more about treatments for stage IV colon cancer . Staging Rectal Cancer Rectal cancer is staged much the same way as colon cancer, but because the tumor is much lower down in the colon, the treatment options may vary. Stage 0 In stage 0 rectal cancer, the tumor is located only on the inner lining of the rectum. agree with http://www.webmd.com/colorectal-cancer/guide/staging-colon-rectal-cancer












Stage IV Colon Cancer Prognosis





The National Cancer Institute, or NCI, describes stage IV as cancer that has spread to distant organs such as the liver, lungs, peritoneum, or ovaries. History The NCI estimates there will be 102,000 new cases of colon cancer diagnosed in the United States in 2010. They estimate there will be 51,370 deaths from colon and rectal cancer combined. The American Cancer Society, or ACS, estimates that of these cases diagnosed, 49,470 will be in men and 53,430 will be in women. They estimate 26,580 of the deaths will be men and 24,790 will be women. You Might Also Like Herbs for Late Stage Significance The prognosis for people with colon cancer depends on whether the cancer has penetrated through the layers of the bowel, whether there are lymph nodes involved and whether the cancer has spread to distant organs. In stage IV, all three of these situations are present. That means that people diagnosed with stage IV colon cancer may receive treatment that is a little different from those diagnosed in earlier stages. Treatment Recurrence of the disease is a major factor in treating people with stage IV colon cancer. Surgery may be recommended if there are few distant metastases that are small enough to remove with the colon cancer in order to help the person live longer. For advanced stage IV cancer, surgery might be recommended to relieve or prevent a blockage and help you be more comfortable. visit this site http://www.livestrong.com/article/257383-stage-iv-colon-cancer-prognosis/
