I would have a physician VISUALLY assess it. Could be alot of things besides cancer.
I have found one the size of walnut on the bottom of my right rib cage also. It is a decent size. It seems when I look this up there is not a lot of info on what it really can be.
Mine is painles and i can somewhat move it. It is on top of my rib cage while lying down but below my rib cage when standing. I am curious to what it could be. Some of the research I have done suggests a Lipoma (non cancerous "fatty tumor").
I was just curious if you have found anymore out about yours. I was also wondering if anyone else had any input.
Hi Dar584 went too my doctor and said it was Lipoma tumor non cancer.My doctor did want me too get it looked at from time too time hope this helps.Let me know if u need anything.
