Most people understand the risks of sun exposure, even if they do not regularly wear sunscreen, but getting younger people to pay attention to this concern can be difficult. A study chose a novel approach to this problem by appealing to teenagers’ vanity and focus on their appearance.

Tinted sunscreens offer all the benefits of traditional sun protection products, plus they have added pigments that give them the ability to block visible light, which can also be harmful to the skin.

Research we're watching

According to a report published March 12 in the journal Cancer, the rate of death from cancer has continued to decline in the United States, dropping on average 1.5% a year from 2001 to 2017. The decline showed up for all ethnic and age groups between 2013 and 2017. The findings were based on cancer incidence data collected by the CDC and the National Cancer Institute.

But not all news was good: the number of new cancer diagnoses in women rose slightly during 2012 to 2016. A more detailed look at cancer deaths among women found a drop in cancer deaths for a majority of the most common cancers, including breast cancer, melanoma, lung cancer, and colorectal cancer. But deaths in women increased when it came to uterine, brain, liver, heart, and pancreatic cancer.

What does that skin spot or growth mean, and when should you have it checked?

Even if you're diligent about sun protection (and you should be), you can still develop skin spots, growths, or other abnormalities.

But are they always cause for concern, or just a normal part of aging skin?

Good news on health –– which seems hard to come by right now –– includes declines in the rates of six out of 10 major causes of death in the United States.

Eczema is a common and chronic inflammatory condition that leaves skin dry and itchy. A large study published in the February 2020 issue of The Journal of Allergy and Clinical Immunology found that people with eczema had an increased bone fracture risk, especially if the eczema was severe. Researchers compared 500,000 adults with eczema to more than 2.5 million people who didn't have eczema. Over a period of five years, people with eczema appeared to have slightly higher rates (7% to 18%) of wrist, hip, pelvis, and spine fractures, compared with people who didn't have eczema. People with severe eczema had much higher rates of hip fractures (50% higher), pelvis fractures (66% higher), and spine fractures (109% higher, or more than double the risk) than people without eczema. The study is observational and doesn't prove that eczema causes bone fractures; it could be that certain medications and lifestyle habits contributed to broken bones in the study. "But based on the findings, people with eczema should be aware their skin condition may increase the risk for osteoporosis and bone fractures, and should talk to their health care provider to decide if preventive measures and screening tests for osteoporosis are warranted. Healthy lifestyle choices, such as getting enough calcium and vitamin D and getting regular aerobic and weight-bearing exercise, are important for everyone and may be particularly important for people with eczema," says Dr. Robert Shmerling, a rheumatologist at Harvard-affiliated Beth Israel Deaconess Medical Center.

Ask the doctors

Q. My skin has been breaking out since I entered menopause. Why is this happening, and what can I do about it?

A. Many women notice changes to their skin at menopause. For some women this means dryness, age spots, or a tendency toward bruising. For others, estrogen levels drop while male hormone levels, such as testosterone, remain the same, which can prompt acne breakouts.

A study of older adults found that those who had had more sexual partners were more likely to have developed cancer, but that does not mean there is a causal connection, and there are many ways that sexual behavior can affect cancer risk.
