What is on my leg? About two years ago a single bump showed up on my right leg about mid thigh then about six months ago another single bump showed up same leg, just under my knee (outter part). They start kind of skin color then become brownish with a waxy look to them. I just noticed a third starting on the same leg inner thigh area. My doctor knows about two of them but only because the third bump I didn't know about when I went there a few weeks ago. Doc said he thinks they are cysts and wants to do a pin point biopsy, but do cysts show up at different times & areas?

Given the huge list of types of cysts, I would think they do. I would follow what your doc is saying right now.

I have dozens of every kind of lump, bump, mole, and tag known to dermatology. My family has had different kinds of skin cancers on both sides.
A brownish waxy uniformly shaped raised bump isn't too likely to be cancerous, but anything can be. Waxy generally means filled with regular fat (oil) or water and oil, and is called sebaceous. It's probably fine. Personally I would go to a dermatologist first, instead of having a biopsy.
