Appearance. Voles, sometimes commonly called meadow mice, are small, ground-dwelling rodents that range from about 5-8 inches long with a body that is more robust than a mouse. They have relatively short legs and tails, and their body fur is brownish and black. The voleâs head is round shaped and the snout is blunt.
Comorbidity must be considered when making recommendations about CRC screening with older patients. In a retrospective study of 404 VA patients over age 75 who underwent colonoscopy and were followed for 5 years, only 8 (2 percent) were diagnosed with colorectal cancer. The majority of patients passed away from other causes. Only age and severity of comorbidity were risk factors for death within 5 years of colonoscopy [3].
You should have a colonoscopy every 10 years starting at age 50. Alternatively, you may get a flexible sigmoidoscopy every five years, a double-contrast barium enema every five years or a CT colonography (virtual colonoscopy) every five years.However, a colonoscopy will be needed if any of those results are positive.fter that, and without any symptoms, the next colonoscopy should be 5-10 years later. For high-risk patients (personal or family history of colon cancer, certain genetic disorders) colonoscopy may need to be earlier and more frequent.
