The symptoms of gallbladder cancer often don't start until the tumor is big or the cancer has spread. Common symptoms of gallbladder cancer include:
Pain or discomfort in the right side of the upper belly (abdomen)
Lumps in the abdomen
A sense of fullness after eating even small amounts
Nausea and vomiting
Poor appetite
Loss of weight without trying
Fever
Yellowing of the skin or the white part of the eyes (jaundice)
Severe itching
Many of these symptoms are also caused by other health problems. Some are a lot like the symptoms caused by gallstones or gallbladder inflammation. But it's important to see a healthcare provider if you have these symptoms. Only a healthcare provider can tell if you have cancer.
