Treatment for women with a type of early breast cancer called ductal carcinoma in situ (DCIS) might not be doing enough to prevent deaths from the disease, says a study published online Sept. 16, 2020, by JAMA Network Open. The study sought to determine whether women diagnosed with DCIS had a higher risk of dying from breast cancer than women who did not have the disease. They looked at 144,524 women who were diagnosed with DCIS from 1994 and 2014 and then treated for the condition. Researchers compared them against women without DCIS from the general population. They found that the women with DCIS had three times the risk of dying of breast cancer in the follow-up period, which ran until December 2016, than women without DCIS. Study authors suggest ways that might identify which women with DCIS need more aggressive therapy to prevent breast cancer death.

Endometriosis occurs in women when tissue similar to the lining of the uterus grows in other places in the body, most commonly within the pelvis, causing pain and other symptoms. Many women with this condition are not diagnosed properly until middle age. There are several options for treatment, and it may take time to find what works best for each person.

Doctors typically recommend that women who have high blood pressure avoid using birth control that contains estrogen to avoid raising risks for a stroke or heart attack. According to a clinical update, this recommendation may be changing for some women with high blood pressure.

Drinking no more than four or five 8-ounce cups of coffee per day—equal to about 400 milligrams of caffeine—helps people get the drink's health benefits with a lower risk of caffeine side effects like anxiety and nervousness.

Q. I've been experiencing some menopause symptoms, such as hot flashes. Can acupuncture help?

Need another reason to quit smoking? A study published in the September 2020 issue of the Journal of Neurology, Neurosurgery and Psychiatry found that women ages 30 to 60 who smoked had four times the risk of having a brain aneurysm (a weakened artery in the brain that bulges and could burst) compared with nonsmokers.

Researchers looked at nearly 550 women who had a brain scan performed, most often because of persistent headaches. The scans showed that 113 of them had one or more brain aneurysms. These individuals were then matched with 113 people who did not have brain aneurysms. In comparing the two groups, the researchers found not only that smoking drove up the risk of finding a brain aneurysm, but also that women who both smoked and had high blood pressure had seven times the risk compared to nonsmokers with normal blood pressure. If future research shows that smokers also have a significantly higher risk of brain aneurysm rupture, women smokers ages 30 to 60 might be candidates for aneurysm screening.
