Virtual Colonoscopy
CT colonography, commonly referred to as virtual colonoscopy, is a minimally invasive test that provides three-dimensional images of the colon. These images are useful in detecting polyps, cancer and other lesions in the large intestine.
Virtual colonoscopy is less invasive than conventional colonoscopy. Medical experts recommend regular screenings for men and women over age 50; earlier for those at high risk.

Stroke
Stroke symptoms come on suddenly and may include numbness or weakness in the face, arm or leg, especially on one side of the body.
Successful treatment usually depends on emergency care given within the "magic window" of time, within three hours of stroke onset.

Prostate Cancer
There are no symptoms for early prostate cancer when it is most treatable, but it can be detected early through regular screening. Imaging tests to detect the disease include ultrasound or MRI. Regular screenings are recommended for men over 50.
Treatment depends on the stage of the cancer, and may include surgery, radiation therapy or other methods.

Ovarian Cancer
Pelvic imaging and blood tests are currently the best methods of screening for ovarian cancer. Early diagnosis is the key to successful treatment.

Breast Cancer
Women over 40 are urged to get yearly screening mammograms. Annual screenings help detect breast cancer when it is most curable.

Lung Cancer
Coughing, wheezing, hoarseness, and fatigue are just some of the symptoms that are often confused with less serious conditions. Smoking is the major risk, but even non-smokers can develop lung cancers.
As with any form of cancer, early detection is the key to survival. Lung cancer treatments may include surgery, radiation treatments, chemotherapy or one of several interventional radiology procedures. New screening methods such as CT scans are being used in clinical trials.
