Gallbladder cancer is a rare disease that is most often seen in women and Native Americans, as stated by MedicineNet. In addition to a lump beneath the right ribcage, it causes jaundice, fever, bloating, nausea and vomiting and pain. It is difficult to detect gallbladder cancer in the early stages, which means it is usually identified in the later stages.

Liver cancer usually occurs in people over the age of 50, and is more common in men than women. In addition to upper right quadrant lumps, according to Medline Plus, it may present with pain and tenderness in the area, jaundice, an enlarged abdomen and a tendency to bleed or bruise easily. Treatment success depends on how early the cancer is identified.

It is more common for lumps beneath the right rib cage to be caused by liver enlargement, for which there are multiple causes. Infections, toxins and medications can cause the liver to enlarge, including hepatitis, as stated by WebMD. Alcoholism is another cause of enlarged liver, as well as the cirrhosis that arises from it. In some cases, patients may experience cysts and tumors. Finally, heart conditions that impair blood flow may cause the liver to enlarge, including large liver vein blockages, congestive heart failure and small liver vein blockage, according to WebMD.
