A number of studies have shown that weight becomes a risk factor for breast cancer as a woman gets older. A new study confirms it and explains why. While the ovaries are the main source of estrogen before menopause, fat tissue becomes the source of estrogen after menopause. In addition, a report in the Journal of the National Cancer Institute studied more than 2,000 women and found that obese women produce more estrogen and therefore have a higher breast cancer risk compared to those who are normal weight. Researchers note that the findings are important because most of the risk factors for breast cancer, like family history or genes, can't be modified, but weight can be reduced. The finding were reported by the Endogenous Hormones and Breast Cancer Collaborative Group and is published in the Journal of the National Cancer Institute.
The only way to lead this headline is, it's just not fair. More and more, the findings show being overweight can increase your cancer risk if you are a woman, but now it turns out a little extra weight may actually decrease your cancer risk if you are a man! Not all cancers, but specifically, Harvard researchers found that heavier men have a lower risk of developing prostate cancer, that the extra pounds lower testosterone levels in men. It's that hormone that may play a role in the risk of early onset or inherited prostate cancers.
Nobody takes their cat to the movies, but cat owners may bring the same allergy triggers when they find their seat at the show. Researchers in Belgium found high levels of the FEL D-1 cat allergen in movie theatre seats, while the carpet beneath the seat had much lower levels of the irritating substance. FEL D-1 is an enzyme that gets on cats' fur after self grooming by licking. The researchers found that the saliva borne enzyme finds its way to furniture and clothing and then tags along to what ever chair the cat owner chooses later.
