Gallbladder cancer is a malignant tumour that starts in the cells of the gallbladder. Malignant means that it can spread, or metastasize, to other parts of the body.
The gallbladder is part of the digestive system. It is a small, pear-shaped organ under the liver, on the right side of the body. Your liver makes bile, which is a yellow-green fluid that helps your body digest fats. The bile ducts are tubes that carry bile from the liver to the gallbladder. The gallbladder stores bile and then releases it into the small intestine. Together, the liver, gallbladder and bile ducts are called the biliary system or biliary tract.
Cells in the gallbladder sometimes change and no longer grow or behave normally. In some cases, changes to gallbladder cells can cause cancer.
Most often, gallbladder cancer starts in the glandular cells in the lining of the gallbladder. This type of cancer is called adenocarcinoma of the gallbladder. It makes up about 85% of all gallbladder cancers. Cancer can also start in thin, flat cells called squamous cells. This type of cancer is called squamous cell carcinoma (SCC) of the gallbladder. Other gallbladder tumours can have both glandular cells and squamous cells. These tumours are called adenosquamous carcinomas.
Rare types of gallbladder cancer can also develop. These include signet ring cell carcinoma and clear cell carcinoma.
Even though we are high school students, we were able to raise so much money for the Canadian Cancer Society. It just goes to show what can happen when a small group of people come together for a great cause.
The Canadian Cancer Society is actively lobbying the federal government to establish a national caregivers strategy to ensure there is more financial support for this important group of people.
