Lump Under Right Rib Cage

There are many factors that may explain the presence of a lump under right rib cage. The first thing to do if you feel any lump is to have it properly checked by a doctor.

Question 1:

What could a large lump under right rib cage mean? I've begun to feel a lump right below my left breast, not on the breast but under my breast. I already had a tumor excision on my right breast about a year ago, it was benign. The lump I am feeling now is totally different from the first lump that turned out to be a benign tumor. This time the lump is a lot bigger and quite distinctive.


Lumps in the body can vary as being from tumors, infection or cell inflammation. A tumor can either be a solid of fluid-filled cystic growth; it can be benign or cancerous. For most people the word tumor already suggests cancer, which isn't necessarily the case. That is why there should be enough information available on this kind of cell formation. 'Tumor' is simply a very misunderstood word. For a proper diagnosis, you need see your doctor; he will have to examine you again to determine if that growing lump is just another benign tumor or a manifestation of a more serious condition.

Question 2:

I have a knot under right rib cage. I have never bothered about it before until I noticed it getting bigger and the skin is red around it. What can it be?


It would depend on the exact location of the knot or the lump; you should check if it is a part of the bone or soft tissue. Sometimes a knot under right rib cage is due to some trauma, but if you have never been injured, it could be a result of something else. You will need to see your doctor to get properly diagnosed. If the skin around the lump is swelling and turning red, you should not ignore it and go see your doctor. It could be a swollen tumor, a muscle inflammation or an infection due to an injury not healing properly.
