Most cases of colon cancer do not show symptoms, but symptoms such as abdominal pain, weight loss, diarrhea, narrow stools, weakness and rectal bleeding may indicate the presence of colon cancer, as stated by Mayo Clinic. When the symptoms appear, they tend to be different from one person to another depending on the size of the cancer.
In theearly stages of cancer, there may be no any signs, but an individual needsto seek the doctor's attention if he or she notices blood in stooland change in bowel habits. Screening for a colon cancer is usually recommended for people aged 50 years and above. It can help to detect the cancer before the symptoms appear. More screening may be necessary if a patient has other risk factors, such as family history of the disease. Colon cancer is likely to be curableduring its early stages, as stated by MedlinePlus.
Colon cancer can be categorized in different stages, including stage 0, I, II, III and IV, depending on its severity. At stage 0, itis usually in the inner layer of the colon with no symptoms, while at stage IV it has spread to other nearby organs. Reporting any unusual change in the body can help in early detection, thus allowing the condition to be controlled easily.
