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].
If the exam is normal, a colonoscopy should be repeated every 10 years up to the age of 75. If the test detects precancerous polyps, the physician will recommend that colonoscopies be repeated more frequently.If you have a first-degree relative with colon cancer, exams should start between ages 35 and 40,â says Fuchs. Colonoscopy is the most reliable test, because doctors can visually study the entire colon and rectum, Fuchs says.
