CT scanning has many health benefits but also carries a small risk of causing cancer over a lifetime of exposure. The risks for older adults are very small. At any age, it is still wise to limit CT scans to what you need.
Active surveillance: An option for low-risk prostate cancer
After prostate cancer diagnosis, immediate treatment is not the only option. Some men with low-risk cancers can choose to monitor the cancer very closely and treat when the disease progresses. This allows a man to delay or avoid the risks of treatment.
Social engagement and healthy aging
Social engagement, or how connected you are to other people, can be as important to healthy aging as not smoking or maintaining a good weight. Social engagement may also help to preserve memory. Volunteering is a good way to foster social connection.

With aging, many people wake during the night and have trouble falling asleep again. It's important to adopt good sleep habits before considering sleeping pills for persistent insomnia. Counseling called cognitive behavioral therapy can also help.
On call: CoQ10 for muscle aches
There is no solid evidence that taking coenzyme Q10 prevents muscle problems related to taking a cholesterol-lowering statin drug. The risk of side effects from the supplement is low, so it may be relatively safe to try it for a month or two.
On call: Shingles vaccination
The Zostavax vaccine is safe for use by healthy adults to prevent shingles, a painful condition caused by previous infection with the chicken pox virus. It also helps prevents persistent shingles pain, known as post-herpetic neuralgia.
