Hi, i have a mass located on my right lower rib area. i have a hx of rcc with a left nephrectomy. i know i need to see my physician, however hoping you can provide some insight. thanks?

If the mass is superficial, clear margin and soft, it is likely a cyst or a lipoma. If the mass is on one of the rib, it could be a bone cyst. Renal cancer rarely metastasize to the rib by my experience. I doubt if you can feel a mass inside the liver which is in that location. You should see your doctor for confirmation and do not worry much in the mean time. Good luck!

Without an exam it would be pure speculation. Lets hope it is something benign and see you doc asap. Good luck.
