Symptoms of gallbladder cancer include abdominal pain, vomiting, nausea, jaundice and lumps in the abdominal region, according to the American Cancer Society. Less commonly, gallbladder cancer causes loss of appetite, fever, weight loss, abdominal swelling and itchy skin. Greasy or light-colored stools and dark urine are other less common symptoms.
Many of the symptoms of gallbladder cancer mimic those of other conditions, which leads to delayed diagnoses, notes the American Cancer Society. Moreover, the symptoms of gallbladder cancer usually do not occur until the cancer reaches an advanced stage. However, when symptoms are recognizable in the early stages of the disease, treatments may be more successful.
