Q. I was recently diagnosed with prostate cancer. Does the occurrence of one type of cancer indicate a greater risk of developing other kinds?

A. Prostate cancer is the most common cancer among men, and almost every man will get prostate cancer if he lives long enough. In general, prostate cancer that develops after age 60 probably does not increase the risk of getting a different kind of cancer. However, there are some exceptions.

According to a new guideline, testing should start at age 45, but not everyone needs to have a colonoscopy. Other tests are also available.

Colon cancer screenings for people at average risk for the disease should start at age 45 instead of 50, says a new guideline from the American Cancer Society (ACS).

The change to the screening recommendation, which was published in the May 30 issue of CA: A Cancer Journal for Clinicians, was made because the number of colon cancer cases among adults under age 55 rose 51% from 1994 to 2014, and colon cancer deaths in this age group rose 11% from 2005 to 2015.

Women are at higher risk for heart attacks that don't involve blocked arteries — and they should receive the same follow-up treatment as conventional heart attack patients.

For years, people who suffered heart attacks but didn't have major blockages in their arteries — a condition called myocardial infarction with nonobstructive coronary arteries (MINOCA) — were thought to have a less serious form of heart disease. As a result, doctors often opted against aggressive follow-up treatments. But a study published June 15 in the International Journal of Cardiology contributes to the growing body of evidence that MINOCAs merit follow-up treatment.

The study, which looked at data from an online Swedish cardiac registry, found that a quarter of people who were diagnosed with MINOCAs went on to have another major cardiovascular event, such as another heart attack, a stroke, or heart failure. Of the original group of 9,092 people who were diagnosed with MINOCAs (62% of them women), some 2,147 went on to have another cardiovascular event during a follow-up period averaging about 4.5 years.

How old you are when you go through menopause could be influenced by the foods you eat.

Could the foods you eat help determine when you start menopause? They might, says a new study published online April 30 by the Journal of Epidemiology and Community Health. Researchers found that women who ate more fish and beans and other legumes started menopause at a later age, while women who ate a diet heavy on refined pasta and rice went through the change earlier.

Why do the results matter?

How old a woman is when she goes through menopause may have implications for her health. Past research has linked certain health risks to menopause that occurs either very early (before age 40) or late (age 55 or older). Going through menopause at an earlier age has been associated with lower bone density and a higher risk for osteoporosis, cardiovascular disease, depression, and — in some instances — premature death.

It might be surprising to learn that parents can help fight childhood obesity by taking good care of themselves. A new study found that when mothers follow five healthy lifestyle habits, their kids are much less likely to become obese.

Rates of the two most common skin cancers have more than doubled over the past decade. Here's how to protect yourself.

When it comes to skin cancer, there's good news and bad news. First, the bad news. A report published in the June 2017 Mayo Clinic Proceedings found that cases of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) skin cancers have risen 263% and 145%, respectively, over the past decade.

The good news? BCC and SCC are rarely life-threatening and they're usually easy to treat if they're caught early. Plus, there are simple ways to prevent them.
