Eating more ultra-processed foods may shorten life span
In the journals
Need another reason to monitor your intake of ultra-processed foods? Cutting down on your amounts could help you live longer.
In an observational study published online Feb. 11, 2019, by JAMA Internal Medicine, almost 45,000 adults ages 45 and older completed several dietary assessments over a two-year period. On average, ultra-processed foods made up about 15% of their daily diet as measured in grams.
Does endometriosis increase cancer risk?
Ask the doctors
Q. I have endometriosis, and I recently heard that it might increase my risk of certain cancers. Is this true?
A. Researchers have linked endometriosis, an often painful condition that causes endometrial-like tissue to grow outside the uterus, to a higher risk of two types of ovarian cancer — endometrioid and clear-cell subtypes. That said, even though your risk of these cancers may be higher than that of the average woman who doesn't have endometriosis, your chances of developing one of these cancers is still very small — less than 1%.
4 tips for coping with an enlarged prostate
When a man reaches about age 25, his prostate begins to grow. This natural growth is called benign prostatic hyperplasia (BPH) and it is the most common cause of prostate enlargement. BPH is a benign condition that does not lead to prostate cancer, though the two problems can coexist.
Although 50% to 60% of men with BPH may never develop any symptoms, others find that BPH can make life miserable. The symptoms of BPH include:
Do all skin cancers have to be removed?
Ask the doctor

Q. My doctor says I have a small skin cancer on my scalp, but it's not melanoma. Do I really need to have it removed?
A. It's true that melanoma is the most dangerous type of skin cancer, because it can spread throughout the body. You definitely need to have any melanoma removed, to try to excise it before it spreads. Two other types of skin cancer, basal cell carcinoma and squamous cell carcinoma, are more common than melanoma. It sounds like you have one of those. They spread only rarely, but they do grow larger. Not only is this disfiguring, but delay in removing them makes it harder to remove them with only a minimal scar. And cancers on the scalp, when they become large, can be particularly hard to remove.
Fish oil and vitamin D supplements might offer some health benefits
In the journals
Vitamin D and omega-3 fatty acid supplements have had mixed results when it comes to preventing heart attacks, strokes, and cancer in people who have already developed these problems or are at high risk for them. Yet a new study published online Nov. 10, 2018, by The New England Journal of Medicine found they may actually prevent these conditions among people who have never had these problems before.
Researchers recruited almost 26,000 people, ages 50 and older, who had no history of heart disease or cancer. The participants were divided into four groups. People in one group were given daily doses of 2,000 international units of vitamin D (an amount found to be linked to lower disease risk in observational studies) and 1 gram of a drug called Lovaza, which contained 840 milligrams of omega-3s (two to four times the amount in two servings of fish per week). The second group took vitamin D and a placebo, the third group took the omega-3s and a placebo, and the final group took two placebos. After more than five years, the researchers found that those given omega-3s were 28% less likely to suffer a heart attack compared with those given a placebo. Those who ate fewer servings of fish (less than the average of 1.5 servings per week) appeared to have a greater benefit from the additional omega-3s while those with higher fish intake had minimal benefit.
