The COVID-19 vaccine may cause a harmless temporary swelling of lymph nodes that could be mistaken for cancer on a mammogram or other imaging test.

Menstruation is a basic fact of human existence, yet millions of people in the US struggle to afford –– or can't afford –– products like tampons and pads, a problem known as period poverty. Menstrual hygiene products are necessities, not luxuries, and period equity addresses this.

This common problem is often ignored or misunderstood.

Roughly half of women over age 50 have pelvic organ prolapse, a condition in which the uterus, bladder, small intestine, or rectum bulges into the vaginal wall or drops down through the vagina. But unlike with other common health conditions, many women don't talk about it — even with their doctors. For some, this may stem from embarrassment, but in other instances, it's because they think it's just something they need to deal with as they age.

"Women will say to me, 'I thought this was normal because I had kids.' But it's not normal. Not everyone who has had a vaginal delivery or is over 65 has urinary incontinence or pelvic organ prolapse," says Dr. Emily Von Bargen, a Harvard Medical School instructor in Obstetrics, Gynecology, and Reproductive Biology. Pelvic organ prolapse is treatable, and it's not something women have to live with, says Von Bargen.

If you're among the nearly 17 million adults in this country who's had cancer, pay extra attention to your heart health.

Thanks to advances in early detection and treatment, people with cancer are living far longer than in past decades. But cancer survivors should be aware that cancer and its treatments can compromise cardiovascular health, according to a recent study from the CDC.

Researchers studied more than 840,000 adults, including about 69,000 cancer survivors, to see how much cancer "ages" the heart. They found that adult men treated for cancer had hearts that appeared to be 8.5 years older than their actual age, while the hearts of women who survived cancer appeared to be 6.5 years older.

Regular aspirin use is associated with a reduced risk for developing colorectal cancer in older age — but you won't get the benefit if you start the therapy too late in life, according to a Harvard study published online Jan. 21, 2021, by JAMA Oncology. Researchers combined the results of two large studies involving a total of more than 94,000 people who answered health questionnaires regularly and were followed for three decades. Compared with people who didn't take aspirin, people ages 70 or older who took either 325 milligrams (mg) or 81 mg of aspirin at least twice per week had a 20% lower risk for developing colorectal cancer — but only if they had started the therapy by age 65. Starting aspirin therapy at or after age 70 was not associated with significant protection against colorectal cancer. The study was observational and does not prove whether aspirin can or cannot ward off colorectal cancer. But other observational studies have also shown an association between aspirin use and lower colorectal cancer risk. Like any medicine, aspirin isn't risk-free: regular use increases the risk for gastrointestinal bleeding. If you happen to be taking aspirin regularly for other reasons, this might be an added benefit.

Polycystic ovary syndrome is the most common cause of infertility in women. In many cases, women with PCOS have skin and hair issues such as acne, hair loss, or excessive hair growth in places where they normally do not have hair. Treatment options vary depending on the symptoms and each woman's preferences.

Q. I was worried about drying my nails with a lamp or light box at the nail salon because of the potential risk of cancer from the ultraviolet radiation, but my salon recently switched to LED lamps. Are they safer?

A. The light boxes used to cure polish during gel manicures, and to dry traditional nail polish, have raised some concern because — like tanning beds — they emit ultraviolet A (UVA) radiation, which is associated with a higher cancer risk. A 2014 study in JAMA Dermatology found that the level of UVA exposure associated with a gel manicure every two weeks probably isn't high enough to increase the risk of skin cancer significantly, but you are wise to be aware of the issue.

Vaginal discharge can change with age. Here's how to spot signs of a problem that might warrant a trip to the doctor.

Vaginal discharge and bleeding can change during different stages of life, and what's typical for you might not be typical for your sister, your daughter, or your friend. "When it comes to vaginal discharge, a wide range of 'normal' can be considered," says Dr. Kristin Hung, instructor in obstetrics, gynecology, and reproductive biology at Harvard Medical School.

Not only is there natural variation between women, but what's normal for your own body may also change over time. So how can you tell when something is wrong, or if the changes you're noticing are just the result of aging or hormonal shifts? "Typically, most women know their own bodies, and anything new, unusual, or persistent is a reason to seek evaluation," says Dr. Hung. That said, she adds, there are some changes that are pretty typical and others that might warrant a little more scrutiny through a visit to your doctor. Here's how to tell the difference.
