Gallbladder Cancer: Risk factors, Types & Treatment
Cancer of the gallbladder is cancer which begins in the gallbladder. On the right side of your abdomen, just under your liver, your gallbladder is a thin, pear-shaped organ. Bile, a digestive fluid the liver makes, is contained in the gallbladder.
Cancer of the gallbladder is rare. The potential for a cure is very high when gallbladder cancer is detected in its earliest stages. But most cancers of the gallbladder are identified at a late stage when the prognosis is also very poor.
It is hard to diagnose gallbladder cancer because it often causes no particular signs or symptoms. The relatively secret nature of the gallbladder also makes it easier for cancer of the gallbladder to develop without detection.
Gallbladder cancer risk factors
Although the exact causes of gallbladder cancer are unclear, certain factors can increase the risk of a person developing cancer of the gallbladder. These factors are commonly connected to chronic gallbladder inflammation. Popular risk considerations include:
- Gender: Cancer of the gallbladder occurs in women twice as much as in men. The increased incidence of gallstones and chronic inflammation may be linked to this.
- Age: Cancer of the gallbladder happens mainly in people over the age of 65. At diagnosis, the average age is 73.
- Family history: Although the genetic cause is uncertain, in families with a history of the disease, the risk of gallbladder cancer appears to increase.
Conditions of gallbladder cancer
Gallstones: The leading risk factor for gallbladder cancer is the presence of gallstones, which are present in over 75 percent of gallbladder cancer patients. Often, cholesterol and other substances present in the bile from these strong, rock-like deposits. The flow of bile can be blocked by gallstones and contribute to chronic inflammation. However, particularly in middle-aged women, gallstones are very common, and most people with this condition do not develop cancer of the gallbladder.
Choledochal cysts: Bile-filled cysts can grow along the common bile duct that leads from the gallbladder and liver to the small intestine. Through the lining of the cysts, pre-cancerous cells can also expand, increasing cancer risk.
Porcelain gallbladder: This is a condition where the gallbladder wall is covered by calcium deposits, and some, but not all, studies have indicated a connexion between this condition and cancer of the gallbladder. There may also be a link between chronic inflammation and gallbladder calcification.
Gallbladder polyps: These are unusual growths on the gallbladder that are developed. They may be caused by deposits of cholesterol or inflammation. Larger polyps (larger than a centimeter) have a higher risk of becoming cancerous, and when larger polyps are detected, doctors often consider removing the gallbladder.
Gallbladder cancer symptoms
Finding cancer of the gallbladder when it is still at an early stage improves the opportunity for better results. Although symptoms usually do not occur until a tumor has grown or the cancer is at an advanced stage, it may improve the chance of detecting it and treating it at an earlier stage by becoming aware of the potential signs and discussing them with your doctor immediately if you notice them.
Abdominal pain: In general, this pain is concentrated in the upper or upper right abdomen.
Gallbladder enlargement: It can be difficult to notice an increase in its size since the gallbladder is found under the liver and surrounded by other organs, but often during a physical examination, a doctor may feel it. It is also possible to detect an increase in gallbladder size by imaging tests, such as ultrasound.
Jaundice: Yellowing of the skin or the whites of the eyes can be caused by bile backup caused by a duct-blocking tumor.
Other symptoms: Other signs, such as nausea, vomiting, lack of appetite, weight loss, abdominal swelling, extreme itching, or dark, tarry stools, can also be associated with all-bladder tumors.
Gallbladder cancer causes
What causes gallbladder cancer isn’t clear. Doctors know that when healthy gallbladder cancer develops changes (mutations) in their DNA, gallbladder cancer develops. Where other cells will usually die, these mutations allow cells to develop out of control and to continue living. A tumor that can develop outside the gallbladder and spread to other areas of the body is created by the accumulating cells.
In the glandular cells that line the inner surface of the gallbladder, the majority of gallbladder cancer starts. The cancer of the gallbladder that starts in this cell type is called adenocarcinoma. When viewed under a microscope, this term refers to the way cancer cells appear.
Gallbladder cancer types
Gallbladder cancer is very relatively rare. Adenocarcinomas are almost all types of gallbladder cancer, a type of cancer that starts in the gland-like cells that line the digestive tract organs. 90% of diagnoses of gallbladder cancer are accounted for by adenocarcinomas.
Papillary adenocarcinoma is a special subtype of adenocarcinoma that, compared with other types of gallbladder cancers, has a stronger prognosis or outlook. It is also less probable than it would spread to nearby lymph nodes or other organs, such as the liver.
Adenosquamous carcinomas, squamous cell carcinomas, small cell carcinomas, and sarcomas are other less prevalent forms of gallbladder cancers.
Diagnosing gallbladder cancer
Popular methods used for gallbladder cancer diagnosis and disease staging include:
Lab tests: High bilirubin levels can mean that either the gallbladder or the liver is a problem. Albumin, alkaline phosphatase, AST, ALT, and GGT are other markers of abnormal liver and/or gallbladder function that can be detected by a blood test.
It is also possible to verify levels of such proteins known as tumor markers. In patients with certain types of cancers, these proteins are often elevated, but they are not unique to a certain type of cancer, and because of certain non-cancerous conditions, levels can be higher than average. Two tumor markers that may be related to gallbladder cancer are CEA and CA 19-9.
Biopsy: In certain cases, when other tests diagnose gallbladder cancer, a surgeon can first remove the gallbladder and send a sample to the pathologist after. During laparoscopic or cholangiography, a biopsy may be performed. Your doctor can also use a technique called fine needle aspiration when diagnosing gallbladder cancer, in which a thin needle is inserted into the gallbladder to extract cells, typically, under the direction of a CT scan or ultrasound.
Cholangiography: This test allows the bile ducts to be examined by your doctor. In preparing surgery, it can also assist. This test can be conducted either by using an endoscope or an MRI machine or by inserting a needle through the abdominal tissue.
Another technique that can be used to diagnose gallbladder cancer is angiography. Except that the dye is used to analyze blood vessels and flow across the gallbladder and potential tumor, the technique is the same as cholangiography. During this procedure, a contrast dye is inserted into the body, and then X-rays are taken to reveal the gallbladder and surrounding areas.
CT scan: A gallbladder cancer CT scan uses X-ray images designed to provide a clear view of the gallbladder. GE DiscoveryTM PET / CT 600 scanner: This four-dimensional CT scanner creates accurate X-ray cross-sectional images of the body’s structures. It is also designed to allow radiologists to schedule care based on the breathing patterns of a patient.
X-ray: To see if the cancer cells have spread to the lungs, a standard X-ray of the chest may be taken out.
Ultrasound: This procedure is often done on the skin above the abdomen using an ultrasound transducer, or wand. In certain cases, endoscopic or laparoscopic ultrasound can be done by your doctor. The ultrasound device is attached to a tube for these procedures and inserted through the mouth or a small surgical incision.
Surgery will eventually cure cancer of the gallbladder, but all cancers must be removed.
This is only a choice when cancer has been diagnosed early before it spreads to surrounding organs and other parts of the body.
Chemotherapy and radiation are also used to ensure that all tumors are gone following surgery. It is also used to treat cancer of the gallbladder that can not be removed. It can’t cure cancer, but it can extend life and treat symptoms. When cancer of the gallbladder is high-level, surgery can still be performed to relieve symptoms.
It’s called palliative care. Other forms of palliative care may include:
- Medication for pain
- Medication for nausea
Place a tube, or stent, in the bile duct to hold it open so that it can drain. Palliative care is often used when surgery can not be performed because a person is not well enough.

The opportunity for cancer of the gallbladder depends on the point. Early-stage cancer has a far better possibility than advanced cancer. The 5-year survival rate refers to the number of people living with a disease five years after diagnosis. On average, the five-year survival rate for all stages of biliary cancer is 19 percent.
