Perspectives on Colorectal Cancer
 Colorectal cancer is a major health risk and constitutes a public health problem in 
 most Western countries despite widespread use of screening technique 
 to detect early stages of the disease. In the United States alone, more than 
 148,000 people with colorectal cancer diagnosed every year. Over 55,000 
 Deaths occur in the United States due to colorectal cancer. Colorectal cancer is 
 a very common disease, and it is the third most commonmost common form of cancer in both 
 Sexes. In men, third after prostate and lung cancer and in women 
 after lung and breast cancer. Second only to lung cancer 
 Cancer in relation to the number of deaths from cancer. 
 Majority of colorectal cancer (72%) start in the colon and smaller portion 
 (28%) results in the rectum. The lifetime risk that the diagnosis 
 Colorectal cancer in the UnitedStates, 5.9% for men and 5.5% for women. 
 There are several known risk factors for colorectal cancer. As a male 
 represents a higher risk of colorectal cancer compared to women. Increasing 
 Age is associated with an increase in the risk of colon cancer. 
 The incidence of colorectal cancer is higher in African Americans compared to 
 Caucasian. Risk of developing colorectal cancer is much higher for people 
 Life in theIndustrialized nations compared to less industrialized 
 Nations. 
 Diet rich in fat and cholesterol, is at higher risk for developing linked 
 Colorectal cancer. The lack of proper exercise, presence of inflammatory bowel disease 
 Disease, some types of polyps and family history with a diagnosis 
 for colorectal cancer have been associated with a higher risk of developing associated 
 Colon cancer. 
 Early stages of colon cancer can notcause no symptoms. Some people 
 experience nonspecific symptoms such as light could be abdominal pain, bloating or 
 Diarrhea. Occasionally it can cause bleeding and microscopic diagnosis 
 of colorectal cancer would be due to the presence of anemia, suspected of 
 chronic bleeding. Some people may develop, Frank bleeding or symptoms of 
 Intestinal obstruction. 
 Screening for colorectal cancer can detect the disease, in an early stage. A
 rectal examination and examination of stool samples for the presence of 
 microscopic amounts of blood are very common screening tools. Sigmoidocopy 
 and colonoscopy are invasive tests that can detect and 
 It could be removed a few polyps, the precursors of cancer. Less invasive 
 Techniques such as barium enema, virtual colonoscopy, a CT scan machine 
 are also frequently used in screening and diagnosis of colon cancer. Adults
 with an average risk of colorectal cancer should begin 
 Begin screening at age of 50 
 Treatment of colorectal cancer depends on the stage of the disease. Early 
 Stages of colorectal cancer are treated with surgery alone, the later stages of 
 Colorectal cancer treated with surgery followed by chemotherapy with or 
 without radiation therapy. Rectal cancers are more often treated with 
 Radiotherapycompared to colon cancer. Advanced stages of colorectal 
 Cancer, where the disease has spread to other organs, are usually treated 
 with chemotherapy alone. There are several new chemotherapeutic agents and 
 biological medicines for the treatment of cancer. Treatment 
 significant changes of colorectal cancer in the last 10 years has changed significantly. The 
 newer drugs show significantly improved efficacy and prolongation of life
 Life expectancy in patients with advanced colon cancer.
