Alcohol could raise risk of skin cancer
A study published in the British Journal of of Dermatology has found that drinking too much alcohol can leave the skin more sensitive to UV light, and that may make a person at a higher risk of developing skin cancer.
Researchers say ethanol is converted to acetaldehyde soon after being ingested, which is a compound that could make the skin more sensitive. But, they also acknowledged other factors could be at play, including that drinkers may lay out in the sun too long without protective clothing or sunscreen.
Researchers looked at 16 different studies involving thousands of participants. They found that consuming one or more alcoholic drinks a day increased skin cancer by 20 percent. Risk increased proportionally with the amount of alcohol consumed. Those who drank 50g of ethanol daily, or a few strong beers, had a 55 percent chance of developing melanoma, compared with non-drinkers or occasional drinkers.
The scientists suggested that alcohol mixed with UV radiation can alter the body’s normal immune response, which can lead to greater cell damage and promote skin cancer growth.

Breast cancer survivors benefit from yoga
New research suggests that yoga may reduce inflammation and fatigue in women recovering from breast cancer.
For the study, published in the Journal of Clinical Oncology, researchers looked at 200 women recovering from breast cancer, ranging in age from 26 to 76, and had completed treatment for either early or later-stage breast cancer.
Half of the women took 90 minute hatha yoga classes twice a week for 12 weeks, which involved standing, seated and mat poses, along with breathing exercises. They were also encouraged to continue doing yoga at home. The other women were wait-listed for yoga classes and enrolled later.
The women also completed questionnaires about their mood, sleep and eating habits prior to yoga, after they completed, and then three months later. Researchers also looked at inflammatory markers in their blood at these times.
The researchers found that women who took yoga for three months had a 41 percent drop in fatigue, and up to a 15 percent drop in inflammation compared to those who did not take yoga. In three months, the women who took yoga on average were 57 percent less likely to complain about being tired and had up to a 20 percent body-wide drop in inflammation.
Researchers say these benefits may be because yoga promotes better sleep, increases physical activity and lessens stress.
