DASH diet tied to lower colorectal cancer risk

A 2025 research review found that adhering to the DASH diet-which emphasizes eating fruits, vegetables, lean protein, whole grains, nuts, and low-fat dairy products-is linked to a lower risk of developing colorectal cancer.

Exercise boosts colon cancer survival

In a 2025 study of about 900 people treated for colon cancer (followed for an average of eight years), people who took part in a supervised exercise program for three years had about 30% better odds of surviving, compared with people who weren't in the program.

Physical activity of any intensity tied to lower cancer risk

In a 2025 study of more than 85,000 people (average age 63), followed for six years, those who were the most active-even if they were simply doing light-intensity activities-had a 26% lower risk for cancer, compared with those who were least active.

Calcium may cut odds of colorectal cancer, while alcohol may boost them

A 2025 study suggested that boosting dietary calcium intake may reduce the odds of developing colorectal cancer, while drinking more alcohol may raise risks for the disease.

The cancer–heart disease connection

Cancer survivors are more likely to die of heart disease than from cancer-related complications. One reason is that certain cancer treatments can cause cardiovascular complications. But the two diseases share many root causes, including tobacco use and obesity, as well as diabetes and high cholesterol. Growing evidence suggests that people with heart disease may be more likely to develop cancer.

Hidden battles: Keeping cancer secret

A portion of the two million Americans diagnosed with cancer each year choose to keep the news private or tell only a select few people. These patients may wish to avoid extra attention, sympathy, or different treatment; bypass burdening or alarming others; protect their job; feel in control of an uncertain situation; or sidestep judgment if their cancer is related to lifestyle choices. But opting for secrecy can pose several disadvantages, depriving patients of practical and emotional support and aggravating stress, anxiety, and depression.

Boosting breast cancer survival

Although a clinical trial showed daily aspirin use didn't help women with breast cancer avoid recurrence or improve survival, other evidence-backed measures might. Exercise, weight control, and a healthy diet are linked with lower recurrence and longer survival, but alcohol use, smoking, and supplement use are not. While it's not always clear how lifestyle approaches help lower the odds of recurrence or death from breast cancer, healthy measures can improve women's ability to keep other conditions at bay or manage them more effectively.

Pap smears or self-swabs?

Pap tests, the mainstay screening method to detect cervical cancer, are uncomfortable for some women. In mid-2024, the FDA approved a new self-swab test that can detect human papillomavirus, which causes most cases of cervical cancer. The self-swab test collects cells from the vaginal wall instead of the cervix. Clinicians guide women on how to perform the test in a doctor's office. The self-swab method offers women several benefits, including comfort, accuracy, and potentially greater access to screening.

What kinds of cancer screenings should men get as they age?

Of the cancer screening tests for men, tests for colon cancer has the strongest evidence for benefit. Men who opt in for prostate cancer screening may have more options beyond PSA blood testing to more accurately identify aggressive cancers. Other screening tests such as full body scans have not been shown to improve outcomes.

Should I worry about abnormal Pap test results?

Abnormal Pap test results don't always indicate cervical cancer. Most abnormal findings result from the presence of human papillomavirus, or HPV. Typically, the next step is a colposcopy, a test that enables the doctor to look closely at areas that appear abnormal.
