Women with a strong family history of gynecologic or certain other cancers should consider genetic testing.

Chronic back pain (pain that lasts more than 12 weeks) can be more challenging to diagnose and treat compared to short-term pain from an injury. The first-line approach is conservative treatment, such as over-the-counter pain medication, physical therapy, and lifestyle changes. However, sometimes these are not enough, and advanced methods are needed. Depending on the source of chronic back pain, these can include stronger prescription medication, corticosteroid injections, and surgery.

Research suggests that exercise is beneficial in managing insomnia, but current guidelines don’t specify which types may be most effective. A 2025 study found that yoga, tai chi, walking, and running were associated with reduced symptoms of insomnia.
