[|Human|] Hi I have a lump at the bottom of my rib cage in the middle. It does hurt if I press on it.  Its not an excruciating pain.  However, just concerns me bc I had teticular cancer a few years back.  I do play a lot of golf and also played basketball for the first time in approx 2 years last week. I am 39 years of age and just really noticed this a few days ago.
[|AI|]  Hi ! If you played the basket ball a few days back, it could be just a muscle fiber tear below your ribs due to over stretching which have resulted in a small hematoma giving rise to the lump and mild discomfort. It should be relieved with some anti-inflammatory Chat Doctor. However, because of the history of testicular malignancy, I would suggest you to get yourself clinically examined by your treating doctor/surgeon to exclude any other related possibility. Wishing you an early recovery.
