July 26,2012 - The Food and Drug Administration says that baby bottles and children's drinking cups could no longer contain Bisphenol A or BPA, an estrogen-mimicking industrial chemical used in some plastic bottles and food packaging. Reports of potentially negative health effects have made BPA notorious, especially among parents, and led to widespread shunning of products thought to contain the chemical. BPA has been used since the 1960's to make hard plastic bottles, cups for toddlers and the linings of food and beverage cans, including those that hold infant formula and soda. Until recently, it was used in baby bottles, but major manufacturers are now making bottles without it. Plastic items containing BPA are generally marked with a 7 on the bottom for recycling purposes.
Also, a new study in the New England Journal of Medicine questions whether surgery is the right treatment for some prostate cancer patients. Some doctors prefer surgery after diagnosis while others advise just watching and waiting to see if the cancer progresses. Researchers followed more than 700 prostate cancer patients and found those who had surgery did not live longer than those who did not. Many doctors believe watching and waiting is the better option because surgery can come with side effects.
