Sacroiliac joint pain is felt in the lower back and buttocks, usually on one side of the body. The cause is often not known. Common treatments include physical therapy, bracing, steroid injections, and radiofrequency ablation.
Knee pain has many possible causes, including osteoarthritis, meniscus tears, tendon problems, and ligament injuries.

Colorectal cancer is a leading cause of cancer death, but early screening can detect it while it’s treatable, curable, and even preventable. A 2026 study found that use of an at-home stool test was linked to as much as a 43% reduction in colorectal cancer deaths.

Vascular dementia, which results from brain cell damage due to reduced blood flow, can cause slowed thinking, confusion, and other cognitive changes. Carefully controlling risk factors for cardiovascular disease may help prevent vascular dementia.
Epigenetics is the study of how behavior, the environment, and other factors can trigger chemical changes to DNA or nearby proteins that affect how genes work. Collectively, these changes (known as epigenetic marks) may provide clues about health and longevity.
