In fact, according to the National Eye Institute (NEI), 68.3 percent of Americans 80 and older had cataracts in 2010. And the prevalence of cataracts in the U.S. is expected to grow significantly in the years ahead, due in part to the aging of the population. In 2010, roughly 24.4 million Americans had cataracts, and that number is projected to grow to 50.2 million by the year 2050, according to NEI.

If you have been diagnosed with diabetes, you may feel overwhelmed by all the new information you have learned and will continue to learn about managing your diabetes. You already know your main goal should be to get your blood glucose (sugar) levels under control in order to increase your chances of a complication-free life.

Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage when it may be easier to treat. Lung cancer may have spread by the time a person has symptoms. One reason lung cancer is so serious is because it usually is not found until it has spread and is more difficult to treat. Screening may provide new hope for early detection and treatment of lung cancer. Scientists study screening tests to find those with the fewest risks and most benefits. They look at results over time to see if finding the cancer early decreases a person's chance of dying from the disease.
