A review of the epidemiology, aetiology, pathogenesis, diagnosis, and current therapies related to colorectal cancer

Colorectal Cancer, Anatomy and physiology, Epidemiology, Risk factorsAbstract
Colorectal cancer (CCR), the third most frequent cancer in the world in both men and women, is the main reason why gastrointestinal cancers result in death. It also comes in second on the list of common causes of cancer-related deaths. The following conditions increase the risk of this cancer: smoking, bad diet, ageing, intestinal inflammatory illnesses, polyps, and heredity. Ninety percent of those who have colorectal cancer are over 50 years old, with a median age of 64. Those with early diagnosis, however, experience a more aggressive course of the illness. About 49,700 fatalities were attributed to it in 2015, according to the American Cancer Association. Reducing the death rate is the aim of early identification and therapy. The prognosis of the patient is currently determined by their survival rate. The immunochemical stool test, guaiac test, sigmoidoscopy, colonoscopy, and barium enema are a few techniques used to diagnose colorectal cancer. To guide future tactics in controlling the disease's burden through population-based preventative programs, more research on colorectal cancer and global advancements is essential.
