Skin Growths
Most bumps and lumps that occur as we age are harmless growths, spots, or skin tags that remain stable once they have appeared.

Seborrheic keratoses are oval-shaped, brown or black, waxy, wart-like, flat-topped growths on the face, neck, and trunk.

Cherry angiomas (ruby spots) are small, reddish-purple spots most often found on the trunk and upper legs, but also on the face, neck, scalp, and arms. These harmless bumps are clusters of dilated tiny blood vessels (capillaries) and will bleed profusely if punctured. They are increasingly common after age 40.

Skin tags are fleshy, tag-like growths of skin on the face, neck, chest, underanns, and groin.

Sebaceous gland growths are small, yellowish bumps on the forehead and face.

Pre-Cancerous Growths or Patches Solar or actinic keratoses are small red patches caused by long-term exposure to sunlight. These patches have a crusted, scaly, yellow-brown surface. They are considered to be pre-cancerous. If protected from the sun, the patches may grow smaller and disappear. If sun exposure continues, they  may eventually change into skin cancers.

Prevention
Non-cancerous growths such as skin tags, sebaceous gland growths, and seborrheic keratoses usually cannot be prevented. 
To help prevent actinic keratoses, always use a sunscreen that has a sun protective factor (SPF) of 15 or greater.
