New recommendation: Earlier colorectal cancer screening

The U.S. Preventive Services Task Force now recommends that people begin colon cancer screening at age 45 (instead of 50) and continue through age 75. Some evidence suggests that healthy people older than 75 may also benefit from screening.

Battle of the bulges

A majority of people over 60 have diverticulosis, a condition in which tiny bulges (called diverticula) appear in weak areas of your colon’s inner wall. The bulges themselves don’t cause symptoms, but they can lead to bleeding or diverticulitis, which occurs when a diverticulum becomes inflamed or infected. People can reduce their risk by eating more fiber and staying physically active.

Vitamin D and the big C

New research has found an association between high and low levels of vitamin D and cancer risk. However, many older adults don’t get the recommended daily amount of 600 to 800 international units, as the main sources of vitamin D are sun exposure (which many people try to avoid) and certain foods, like fatty fish, fortified milk and cereal. Getting vitamin D levels checked to find a possible deficiency can reveal if someone needs more vitamin D, which may require taking a daily supplement.

Adjusting gut bacteria may improve response to cancer treatment

Gut bacteria may play a role in response to cancer treatments that target the immune system.

Careful! Scary health news can be harmful to your health

A news story about a worrisome or life-threatening ailment might get you thinking about your own health, especially if you happen to have some of the same symptoms. But dramatic or unusual medical stories can bias your thinking and even negatively affect your health decision-making.

Screening for lung cancer

The U.S. Preventive Services Task Force recommends more people should undergo lung cancer screening.

More people now eligible for lung cancer screening

Updated guidelines suggest current and former smokers get an annual lung cancer screening including those who have quit within the past 15 years.

Vitamin D supplements may reduce risk of invasive cancer

A study published online Nov. 2, 2020, by JAMA Network Open found that healthy-weight people ages 50 or older who took a daily 2,000-IU vitamin D supplement had a lower risk for developing advanced or fatal cancer, compared with people who didn’t take the supplement.

Facts about fiber

Fiber improves digestion and may help lower a person’s risk for heart disease, diabetes, and cancer. But according to the 2020–2025 Dietary Guidelines for Americans, most people meet only half their daily fiber needs. The main reason is not following a basic healthy diet with foods high in fiber. Making small changes in dietary habits and adopting new fiber-rich foods can help people reach their quota.
