Colorectal cancer, also known as colorectal cancer, is a type of cancer that arises from the colon or rectum (parts of the large intestine) due to abnormal growth of cells that have the ability to attack and spread to other organs in the body. Signs and symptoms of this disease and the presence of feces in the stool and change in bowel movement and weight loss and feeling tired and tired all the time. Most cases of colorectal cancer occur due to lifestyle factors and age, with few cases due to unknown genetic factors. The risk factors for this disease include diet, obesity and smoking, and physical activity. Dietary factors that increase the risk of this disease include eating red meat and processed meats (such as salted, dried, fermented, smoked meat, canned meat and meat-based sauces) as well as alcoholic beverages. Also serious are inflammatory bowel diseases including Crohn's disease and ulcerative colitis. Some inherited genetic disorders that may cause colorectal cancer include lupus erythematosus and Linch syndrome, but they account for less than 55% of the cases. Usually, the infection begins in the form of a benign tumor (often in the form of an excess diet) and over time turns into a cancer. Bowel cancer is diagnosed by obtaining a sample of the colon (called a biopsy) through the procedure of the X-ray or colonoscopy. This is followed by a medical imaging procedure to determine the extent of the disease. Cancer screening is an effective procedure to prevent and reduce deaths from colorectal cancer, and medical examinations are recommended from the age of fifty to seventy-five. During laparoscopic colonoscopy, small sepsis can be removed, if any. If a large tumor or a tumor is detected, a biopsy is performed to examine whether it is cancerous. Some drugs, such as aspirin and other nonsteroidal anti-inflammatory drugs, help reduce the risk of the disease, but it is not recommended to be used regularly for this purpose because of its side effects.
