Certain fruits, vegetables, nuts, and seeds have been labeled "superfoods" because, compared with other foods, they have higher amounts of certain vitamins and minerals and powerful antioxidants. They often are associated with combating high blood pressure, diabetes, heart disease, and even some cancers. But instead of focusing on eating more of individual foods, experts suggest building "superplates" that include a variety of superfoods.

A study published by JAMA Network Open found that people taking vitamin D supplements were less likely to have a cancer that spread from the original tumor site to another part of their body or one that proved fatal. However, this risk reduction was only seen in people who were at a normal weight, not those who were overweight or obese. The study did not find that people who took vitamin D were less likely to develop cancer over all compared with those who did not.

The most common non-melanoma skin cancers are basal cell carcinomas and squamous cell carcinomas. They aren’t usually life-threatening, but they can be quite dangerous. They can bleed, hurt, and eat away at skin. If left untreated, they can erode through important structures like the nose, eyes, bones, or muscles. If they become very large, they can spread, and in rare cases cause death. Treatment ranges from scraping out skin cancers with surgical tools to Mohs surgery, a procedure that spares as much healthy skin as possible.

The increasing size and visibility of the transgender population has implications for public health. Hormone treatment given to transgender women lowers the overall risk of prostate cancer, but the risk of a trans woman developing the disease is not zero.

Cervical cancer is curable when caught early through routine screening, so research showing a surprising rise in advanced cancer cases in some groups is worrisome. Two Harvard experts share insights about the research and advice on how people can best protect themselves.

Side effects from both older and newer cancer therapies can affect the heart and blood vessels, possibly causing serious, sometimes life-threatening complications. People diagnosed with any type of cancer should ask their doctor whether their planned treatment might lead to cardiovascular problems. Those ages 65 and older and anyone with risk factors for heart disease (such as high blood pressure or diabetes) may want to request a referral to a cardio-oncologist. These specialists focus on preventing and managing cardiovascular problems in people who are undergoing (or have completed) treatment for cancer.

While ovarian cancer is not always inherited, family history is the top risk factor for the disease, which is diagnosed in 20,000 American women and kills 13,000 annually. Symptoms, such as bloating, pelvic pain, bowel or bladder habit changes, and unusual vaginal discharge or bleeding, are often vague and subtle until the disease is advanced, making it hard to detect and cure. No standard screening test is available for ovarian cancer. Women with symptoms can ask for a pelvic ultrasound. Women with a family history should seek genetic counseling and testing.

People exposed to long-term stress have a higher risk of dying from cancer, according to a 2022 study. The connection may be related to high levels of the stress hormone cortisol.

Groundbreaking cancer treatments continuously emerge from labs and research trials. Three Harvard oncologists share what stands out in their respective fields of prostate, lung, and colon cancer, the most common cancers among men. Examples include greater roles for immunotherapy, targeted therapy, and intensive hormonal treatments.
