Small lump on lower left back right at or a little above hip bone. it moves when touched, no pain, kind of squishy. kidney cancer? cancer?

Lipoma: You are likely describing a benign lipoma. Please consider seeing your health provider if it enlarges or becomes painful.

Less likely bad: If this bump is small, moves around and just beneath the skin it is likely a cyst or fat collection. Both are harmless. If the bump is painful, red or very large and deep you should have that examined. Good luck
