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.

A 2022 study suggests that eating meat (including poultry) fewer than five times a week may protect people from cancer. Consuming only fish and no meat or following a vegetarian or vegan diet may offer even greater protection.

There are several at-home screening tests for colorectal cancer. The most accurate are a fecal immunochemical test (FIT) and a multitarget stool DNA (mt-sDNA) test (Cologuard), also known as a FIT-DNA test. The FIT test uses antibodies to detect blood in stool, and must be done once a year. The FIT-DNA test can identify DNA from cancer cells in the stool and also has a FIT component to look for blood. This test may be repeated once every three years.

A groundbreaking blood test might someday identify cancer in people with unexplained but worrisome symptoms like unexplained weight loss, frequent fatigue, constant nausea, and new pain.

Following a plant-based eating pattern, such as a vegetarian, vegan, or Mediterranean diet, helps manage cholesterol and lower the risk for heart disease. Studies have suggested that some elements of these diets also help protect against cancer, although the best approach is unclear. Experts suggest embracing an overall healthy diet that includes various fruits and vegetables, along with legumes and whole grains, along with cutting down on red meat, processed foods, and sugar-sweetened beverages.

According to a new study, many people who have survived cancer treatment experience poor sleep long after treatment has ended. These people also reported emotional distress, financial hardship, and concern that their cancer might return. Many sleep disorders can be treated successfully, but an accurate diagnosis is essential to choosing the correct treatment.
