Skin tags look like tiny bits of hanging skin and typically occur in sites where clothing rubs against the skin or where there is skin-to-skin friction, such as the underarms, neck, upper chest, and groin. Skin tags are not present at birth and their frequency increases with age. Skin tags can be observed in about 25% of adults. Studies have shown a genetic predisposition to the development of skin tags. Therefore, skin tags can run in families. A skin tag is medically termed an acrochordon. Sometimes, other terms have been used to refer to skin tags.
1 At least half of all people with pancreatic cancer (and all people with ampullary cancer) have jaundice. While jaundice can be a sign of cancer, more often it is caused by something else.

Pancreatic cancer usually doesn't cause symptoms right away, but can cause yellowing of the skin and eyes, pain in the abdomen and back, weight loss, and fatigue. Some risk factors for developing pancreatic cancer include smoking, long-term diabetes, chronic pancreatitis, and certain hereditary disorders.
