While the bone-weakening disease osteoporosis most often strikes women, about 6% of men ages 65 and older have it. Preventing osteoporosis and treating it if it occurs focuses on stopping or at least slowing bone loss.

Raising low testosterone levels or taking a class of drugs known as bisphosphonates also may help.

Skin lumps or bumps occur on or just under the skin. Most are harmless. Aside from basal and squamous cell skin cancers, most other skin lumps are epidermal cysts or lipomas.

A doctor should also evaluate growths that grow quickly, bleed, look infected, or feel painful. Most skin lumps or bumps don't need treatment.
