Colon Cancer or Colorectal Cancer (CRC) contributed to 9.2% of all major cancer worldwide, as per the Globocan Report 2018. The report mentions that over 1.8 million new cases were reported, with it being the third most common cancer in males. This impacts up to 7,46,000 new cases in males and 6,14,000 in females. What Is Colon Cancer?It is a disease of large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum and anus make up the large intestine. The ileocecal valve that is located at the opening between the ileum and the large intestine controls the flow of chyme from the small intestine to the large intestine. It happens when abnormal cells invade the wall of the rectum and neighbouring tissue. These are called polyps or growths in the inner lining of the colon. This starts in the innermost lining of the colon in the mucosa, which contains cells that release mucus and other fluids. When the cells mutate, it creates a colon polyp. Over time, colon polyps become cancerous. If it is left untreated, it could work its way through a layer of tissue, and muscle and then to the outer layer of your colon. It can also spread to other parts of your body via lymph nodes or your blood vessels. What Are The Symptoms?Blood In Your StoolIf you notice blood in your stool or notice that your stool looks bright red, you must go see a doctor. It may also be haemorrhoids or anal tears. Change In Bowel HabitsIf you have persistent constipation or diarrhoea. Or if you feel like you need to poop every time you go to the bathroom, it is advisable to go see a doctor. Belly Pain or Bloated StomachSpeak to your healthcare provider if you feel sudden abdominal pain or feel bloated, which lasts more than a week, or if you feel nauseated, go see a doctor. Other symptoms include unexplained weight loss, vomiting, fatigue and shortness of breath. What Causes It?Certain lifestyle choices can increase the risk of colon cancer. Smoking: using tobacco products whether it is chewing or smoking can cause colon cancerAlcohol use, eating high-fat and high-calorie foods and consuming processed meat can also lead to colon cancer. Furthermore, a sedentary lifestyle without any physical activities. Certain medical conditions can increase the risks of colon cancer, including inflammatory bowel disease, lynch syndrome and familial adenomatous polyposis. If you have a family history of colon cancer, it may increase your risk of getting colon cancer. How To Get Diagnosed?There are certain tests that can help you with its diagnosis:Complete Blood Count (CBC), comprehensive metabolic panel (CMP), and carcinoembryonic antigen assay (CEA) which detects the cancer cells and normal cell release in your bloodstream. A high CEA level may be a sign of colon cancer. Other tests include X-rays, CT scan, MRI scan PET scan, ultrasound, biopsy. Treatment Of Colon CancerPolypectomy: This procedure removes cancerous polyps from the colon.Partial Colectomy (Colon Resection): Surgeons remove the portion of the colon containing the tumor, along with some surrounding healthy tissue, and reconnect the healthy sections of the colon in a process called anastomosis.Surgical Resection with Colostomy: Similar to a colectomy, but if reconnection isn’t possible, the bowel is moved to an opening in the abdominal wall, where waste is collected in a bag (colostomy).Radiofrequency Ablation: This procedure uses heat to destroy cancer cells.Surgery may be combined with adjuvant therapy, which is treatment before or after surgery. Additional treatments, especially for cancer that has spread or returned, may include:Chemotherapy: Drugs are used to shrink tumours and alleviate symptoms.Targeted Therapy: This treatment focuses on specific genes, proteins, and tissues that contribute to cancer growth. A common method is monoclonal antibody therapy, where lab-made antibodies attach to and destroy cancer cells.PreventionAvoid Tobacco: If you smoke, ask your healthcare provider for help quitting through smoking cessation programs.Limit Alcohol: Consume alcoholic beverages in moderation.Maintain a Healthy Weight: Keep your weight in a healthy range to lower your risk.Eat a Balanced Diet: Include plenty of fruits and vegetables in your meals, while reducing red meat, processed foods, and high-fat options. Drinking coffee may also reduce the risk of colon cancer.Monitor Family Medical History: If colon cancer or advanced polyps run in your family, or if a relative had cancer before age 45, share this information with your healthcare provider.Follow Screening Guidelines: Regular screenings are key to early detection. If you have chronic irritable bowel disease or a family history of colon cancer, your provider may recommend starting screenings earlier than age 45.
