Colon cancer ranks second in cancer deaths in men and women.
Colon cancer arises from structures called polyps that protrude into the intestinal cavity.
Colon cancer risk is associated with dietary habits, lifestyle and genetic factors. Age and family history increase the risk of colon cancer. The incidence of colon cancer increases significantly over the age of 50.
Recent data have shown that the incidence of colon cancer has increased in people under the age of 50.
Inflammatory bowel diseases such as Crohn’s and ulcerative colitis have an increased risk of colon cancer. Regular colonoscopy follow-ups are required in these patients.
Many patients with early colon cancer do not have any symptoms. Most patients do not have a family history. Many patients apply in advanced stages and the death rate from the disease is increasing. Signs and symptoms such as weight loss, abdominal pain, blood in the stool, anemia, iron deficiency, diarrhea, constipation can be seen in colon cancer.
Colon cancer precursors are considered as polyps containing adenoma. Colonoscopy controls can be performed after removal of detected adenomatous polyps and at regular intervals of treated colon cancer patients.
A colonoscopy can be performed to screen for colon cancer in healthy people at age 50 and every 10 years thereafter without any additional risk factors.Colonoscopy examination should be started at an earlier age and repeated at more frequent intervals for colon cancer screening of individuals with a family history of colon cancer or adenomatous polyps.
Since the disease progresses and does not show any symptoms until the last stage, it may be necessary to have a colonoscopy, especially after the age of 50, even if there are no complaints.
