For example bacteria or the other waste. • Liquid and salt are the first ones to be removed. • Afterwards, the remaining waste makes its way to the sigmoid, the place where it is stored. • The waste is then dumped into the rectum (once or twice in a day ), when the human body is ready for bowel movement.

Risk Factors • Low fibre and high fat diet • A sedentary lifestyle • Diabetes • Obesity • Alcohol • Radiation Therapy for cancer
Stages of Colon Cancer • Stage 0 • Stage 1 • Stage 2 • Stage 3 • Stage 4
Stage 0 • Very early stage of the cancer. • It is also known as carcinoma in situ • It has not grown in any other tissue than inner layer of the colon.
Stage 1 • When the cancer grows into the next layer of the tissue. • But the reach of cancer is limited to lymph nodes or other organs.
Stage 2 • The point when cancer has reached the outer layer of the colon. • And it has not spread beyond the colon.
Stage 3 • When the cancer has spread through outer layer of the colon. • When the cancer has reached to one or even to three lymph nodes. • But has not spread to distant sites.
Stage 4 • The cancer has reached other tissues beyond the wall of the colon. • As stage 4 progresses, the cancer reaches distant parts of the body.
Treatment Options • Treatment will depend on the type and stage of the cancer, and the age, health status, and other characteristics of the patient. • There is no single treatment for any cancer, but the most common options for colon cancer are surgery, chemotherapy, and radiation therapy. • Treatments seek to remove the cancer and relieve any painful symptoms.
Colonoscopy • Colonoscopy which is also known as coloscopy is an endoscopic examination. • Examination of the large bowel and other part of the small bowel which are situated away. • It is performed with a CCD camera, fibre optic camera on a tube that passes through the anus.
Double-Contrast Barium Enema • It is a double-contrast barium enema that is also a form of contrast radiography. • The x-rays of the colon and rectum are taken using two forms of contrast to make the procedure of analysis of the structures easier. • A liquid containing barium is put into the rectum
Surgery • A surgical procedure to remove part or all of the colon is called a colectomy. • The surgeon removes the part of the colon containing the cancer and the surrounding area. • Nearby lymph nodes are also usually removed. • The healthy portion of the colon will either be reattached to the rectum or attached to a stoma depending on the extent of the colectomy.
Chemotherapy • It is generally used to treat cancer that has spread as the medications travel through the whole body • So the treatment occurs in cycles, so that the body has decent time to heal between doses.
Side Effects of Chemotherapy • Hair loss • Nausea • Fatigue • Vomiting
Radiation • Radiation treatment damages and kills cancer cells by focusing high-energy gamma-rays on them. • Radioactive gamma-rays are emitted from metals such as radium, or from high-energy x-rays. • Radiotherapy can be used as a standalone treatment to shrink a tumor or destroy cancer cells, or alongside other cancer treatments.
Side Effects of Radiation • mild skin changes resembling sunburn or suntan • nausea • vomiting • diarrhoea • fatigue • appetite and weight loss
