Anti-inflammatory medications may play a role in ovarian cancer risk. A study by researchers at the Harvard T.H. Chan School of Public Health found that taking low-dose aspirin regularly appears to reduce the risk of ovarian cancer by 23%. However, long-term heavy use of ibuprofen (Advil), naproxen (Aleve), and other nonsteroidal anti-inflammatory drugs (NSAIDs) seems to increase risk.

The study, published online October 4 by JAMA Oncology, looked at data on more than 200,000 women who participated in the Nurses' Health Study and Nurses' Health Study II. Among the group studied, 1,054 women went on to develop ovarian cancer. Researchers then looked at what type of medications the women took on a regular basis. They found that women who took at least 10 doses of NSAIDs a week for multiple years had an increased risk of ovarian cancer. Women who took low-dose aspirin regularly seemed to have a reduced risk — but the same was not true among women who took a standard-dose aspirin.

A new study published online August 10 by the Journal of the American Medical Association shows that women with ductal carcinoma in situ (DCIS) — cancerous changes to the cells inside the milk ducts of the breast — may have better results if they have radiation in addition to a lumpectomy.

Researchers examined 15-year outcomes in 140,000 women with DCIS who underwent either lumpectomy or mastectomy alone, or both lumpectomy and radiation. Women who had radiation in addition to lumpectomy procedures were slightly less likely to die from breast cancer than women who had either a lumpectomy or mastectomy procedure alone.

Following a specific cancer prevention diet may help you lower your overall risk, according to a study in the August 2018 Cancer Research.

The diet from the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) emphasizes a plant-based diet rich in whole grains, vegetables, fruits, and legumes like beans and lentils, with limited amounts of red or processed meat (no more than 18 ounces per week) and a strong emphasis on eliminating all processed foods, sugar-sweetened drinks, and alcohol.

A test that screens for human papillomavirus (HPV) beat a commonly used cervical cancer screening method in detecting changes that may lead to cervical cancer, according to a study published July 3 in The Journal of the American Medical Association. Some 19,000 women were screened for cervical cancer using either the HPV test or a more traditional and commonly used liquid-based cytology test. After 48 months, all the women were tested again using both tests. Researchers found that among women who'd had a normal initial screening, those who'd been screened with the HPV test had significantly fewer grade 3 or worse precancerous cervical changes at the final testing compared with those screened with liquid-based cytology.

In response, the U.S Preventive Services Task Force now recommends either HPV testing only once every five years or liquid-based cytology once every three years for women ages 30 to 65.

Q. I was recently diagnosed with prostate cancer. Does the occurrence of one type of cancer indicate a greater risk of developing other kinds?

A. Prostate cancer is the most common cancer among men, and almost every man will get prostate cancer if he lives long enough. In general, prostate cancer that develops after age 60 probably does not increase the risk of getting a different kind of cancer. However, there are some exceptions.

According to a new guideline, testing should start at age 45, but not everyone needs to have a colonoscopy. Other tests are also available.

Colon cancer screenings for people at average risk for the disease should start at age 45 instead of 50, says a new guideline from the American Cancer Society (ACS).

The change to the screening recommendation, which was published in the May 30 issue of CA: A Cancer Journal for Clinicians, was made because the number of colon cancer cases among adults under age 55 rose 51% from 1994 to 2014, and colon cancer deaths in this age group rose 11% from 2005 to 2015.

Q. Should pregnant or breastfeeding women and their children use sunscreen?

A. The American Academy of Dermatology recommends that people avoid applying sunscreen to the skin of babies younger than 6 months of age, and instead shield them from the sun, keeping them in the shade as much as possible. It's also a good idea to protect them from the sun using clothing, hats, and sunglasses.
