Sporting clays is a refreshing change from the predictability of skeet and the limited variability that the game of trap offers (44 degrees side to side, 5 set positions, 8-12 foot throw height, 16 yd line, etc).
Lipomas are benign fatty growths that do not grow quickly, but of course they must grow from somewhere, so they do grow. If a lipoma is small, does not show without touching it, and is not painful, I recommend generally leaving it alone.
A lipoma is a slow-growing, fatty tumor situated between the skin and the muscle layer that moves readily with pressure. Lipomas often occur in the neck, shoulders, back, arms and thighs. They could be several and persists for years and can occur at any age. A lipoma is usually harmless.
