What Is Gallbladder Cancer?
The gallbladder is a small organ beneath the liver that stores bile. Bile breaks down fat in the foods you eat and helps you digest food. There are several forms of gallbladder cancer, including:
- Adenocarcinoma: About 90% of gallbladder cancers are adenocarcinoma, which develops in the gland cells. A type of this cancer called papillary adenocarcinoma is less likely than other types of gallbladder cancer to spread to other organs.
- Rarer types of gallbladder cancer include:
- Sarcoma: Cancer of the soft tissue.
- Small cell carcinoma
- Adenosquamous carcinoma: Cancer that impacts two types of cells, squamous cells, which line organs, and gland-like cells.
- Squamous cell carcinoma: Cancer in the lining of the gallbladder tissue.
