Endoscopy and colonoscopy are the initial steps in diagnosing significant disorders, some of which are lethal, such as colon cancer. According to the American Cancer Society, over 95,000 instances of colon cancer will be diagnosed in 2016, with over 49,000 individuals dying as a result. Early detection can increase your chances of survival dramatically. A colonoscopy can detect polyps (growths) on the lining of the colon that would not be seen otherwise. The polyps can be removed before they become cancerous. Colon cancer is a major cause of death worldwide. It is estimated that there will be approximately 50,000 deaths from colon cancer in 2016. Although early diagnosis can increase your chance of survival, only 10% of people with colon cancer are alive after five years. This is because most cancers spread around the body by forming small clusters of cells that can travel through blood or lymph systems to other parts of the body. These clusters are called metastases. The best way to prevent colon cancer is by following a healthy diet that includes plenty of fruits and vegetables and reduces your risk of developing diseases associated with colon cancer, such as diabetes and obesity. A colonoscopy should be done by anyone who has been prescribed aspirin for heart health reasons because it can reveal lesions on the inside of the stomach known as gastric ulcers.
