Left-handers make up only 10% of the population. Despite some common beliefs, science has yet to show that left-handers have any specific advantages or disadvantages over right-handed people in terms of physical abilities, cognitive health, or longevity.

Current guidelines for women under 65 with early-stage breast cancer recommend following lumpectomy with radiation therapy, but emerging research could expand the option of skipping radiation to some women as young as 55.

Palliative care is a medical specialty meant to help people during many different stages of health. Many people who might benefit from palliative care do not receive it; if more people understand it, more people can take advantage of it.

Cooking with gas stoves releases nitrogen dioxide and gas appliances introduce other toxic chemicals into homes, but people can take steps to protect their household and help improve outdoor air quality, too.

Proton-pump inhibitors are a commonly prescribed anti-acid medication, but new guidelines from the American Gastroenterological Association recommend that they should be taken at the lowest dose and shortest duration for the condition being treated.

A 2022 study found that women who begin colorectal cancer screening at age 45 with colonoscopy or sigmoidoscopy are far less likely to develop the disease than women who don't undergo any screening or who start screening at age 50.

Around menopause, a decline in estrogen can trigger low-grade inflammation that leads to unexpected symptoms from head to toe. Symptoms can affect the digestive tract, skin, joints, eyes, ears, and heart, among other areas. A 2022 study found that estrogen loss can even fuel the jaw pain known as temporomandibular disorder. A year or longer can pass before many women connect symptoms with menopause. Women can take lifestyle measures to lower inflammation, such as eating more fruits and vegetables, avoiding processed foods, and exercising.

Clostridioides difficile, a bacterium that causes severe diarrhea and colon inflammation, is common in hospitalized people. New research suggests that even patients who are not diagnosed with the infection in the hospital can bring it home and expose family members.

Fiber-rich diets may lower the risk of heart attack and stroke, in part by decreasing inflammation. This benefit appears to be facilitated by the breakdown of prebiotic fiber in the gut microbiome to create short-chain fatty acids. These compounds circulate through the bloodstream and interact with specific receptors on cells that quell inflammation. Short-chain fatty acids may also play a role in keeping blood sugar, blood pressure, and cholesterol levels in check, as well as helping to prevent harmful blood clotting.

A new study found a higher risk of melanoma among people who ate the most fish, but limitations of this research mean it's premature to draw any conclusions about a relationship between eating fish and melanoma risk.
