Some of the more common symptoms of gallbladder cancer include:
Abdominal (belly) pain: Most often it's in the upper right part of the belly.
Nausea and/or vomiting: Some people with gallbladder cancer sometimes have vomiting as a symptom.
Jaundice: If the cancer gets big enough to block the bile ducts, bile from the liver can’t drain into the intestines. This can cause a greenish-yellow chemical (called bilirubin) in the bile to build up in the blood and settle in different parts of the body. The yellow coloring of jaundice can often be seen in the skin and the white part of the eyes.
Lumps in the belly: If the cancer blocks the bile ducts, the gallbladder can swell. Gallbladder cancer can also spread to nearby parts of the liver. These changes can sometimes be felt by the doctor as lumps on the right side of the belly. They can also be seen on imaging tests such as an ultrasound.
