Lipomas can be worrisome when they appear, but in actuality, they're harmless, just growths of fatty adipose tissue that form below the skin. They can show up all over the body, though they are most commonly seen on the torso, neck, and armpits, and can be the size of a pea or much larger.
Lipomas are the most common form of soft tissue tumors. Despite this somewhat scary classification, lipomas turn into cancer only in extremely rare instances. If you find a lump on your body that seemingly appears out of nowhere, it could very well be a lipoma. Soft and rubbery to the touch, moveable, and painless, lipomas tend not to come with any symptoms. Researchers are not yet sure what causes the growths, but some rare lipomas appear to develop due to an inherited gene.
