Most cases of chest pain don't signal heart problems. While chest discomfort of any kind should never be ignored, many conditions can trigger it. These include gastroesophageal reflux disease, gallstones, asthma, ulcers, anxiety, COVID, esophagus spasms, costochondritis, pulmonary embolism, pleurisy, aortic dissection, and pericarditis. Chest pain is likely to be unrelated to the heart if it's brief, triggered by eating, doesn't worsen with exercise, occurs only with movement, coughing, or breathing deeply, or it's localized to one spot.

In a 2023 study, people who didn't exercise regularly but accumulated three and a half minutes of vigorous daily activity (such as stair climbing) had a 32% lower risk for developing cancer, compared with non-exercisers who didn't do any vigorous activity.

Thousands of miles of veins throughout the body bring blood to the lungs to pick up oxygen and nutrients, and get rid of carbon dioxide before returning to the heart to be pumped out again. How do veins work, what problems can occur, and how can you keep these vital blood vessels healthy?

The human body has excess capacity — that is, our organs have more reserve than most of us will ever need. Why are we built with this natural redundancy? And which body parts can safely fail or be removed without impairing health?

According to a 2023 observational study, greater cardiorespiratory fitness in men was linked to a lower risk of death from colon, lung, or prostate cancer.

RSV is a common virus that just causes cold symptoms for most people. But for infants up to eight months, and for babies and young children with certain health problems, it can be very dangerous. A new immune-boosting shot may help.

Respiratory syncytial virus, or RSV, is the leading cause of bronchiolitis and pneumonia in children under a year old. Usually, cases drop in spring and summer, but the pattern is changing and parents should be watchful.

Death risk from breast cancer that's treated early appears to be falling, according to a large 2023 study. The risk of dying from the cancer within five years dropped from about 14% for women diagnosed in the 1990s to about 5% for women diagnosed between 2010 and 2015.
