Is It Time to Wear a Mask Again?
  + stars: | 2023-08-29 | by ( Dani Blum | More About Dani Blum | ) www.nytimes.com   time to read: +1 min
As new Covid variants gain traction, reinfections become more common and cases climb in certain areas, a few schools and businesses are reinstating mask requirements. Here’s a refresher on where, when and how to mask. When should you wear a mask inside? Everyone’s risk tolerance varies, Dr. William Schaffner, an infectious disease specialist at the Vanderbilt University School of Medicine, said. “Certainly every time you add another person to the room, particularly people who are within three to five feet of you, that increases your chance of getting infected, exponentially,” Dr. Pekosz added.

The details of the trial were presented Thursday at the San Antonio Breast Cancer Symposium. The trial involved 708 adults with HR-positive, HER2-low or -negative breast cancer whose disease has recurred or progressed during or after certain previous treatments. About three-quarters of women with metastatic breast cancer have HR-positive breast cancer. He points to the cancer drug Avastin, which was initially touted as having an advantage in progression-free survival for metastatic breast cancer. Burstein said he is encouraged by many of the presentations at the San Antonio Breast Cancer Symposium.
CNN —Scientists are uncovering new details in the connection between using certain hair straightening products, such as chemical relaxers and pressing products, and an increased risk of cancer in women. The study, published Monday in the Journal of the National Cancer Institute, estimates that among women who did not use hair-straightening chemical products in the past 12 months, 1.6% developed uterine cancer by age 70, but about 4% of the women who frequently use such hair-straightening products developed uterine cancer by age 70. That finding “also communicates that uterine cancer is indeed rare. “In this study, women with frequent use in the past year had an over two-fold higher risk of uterine cancer,” she said. The researchers found a strong association between hair straightening products and uterine cancer cases but the use of other hair products – such as dyes and perms or body waves – was not associated with uterine cancer.
