Having a stent put in is usually a safe procedure. The most likely side-effect is some skin soreness if you have it inserted through your skin (percutaneously).
Gallbladder cancer is caused by an abnormal and uncontrolled growth of cells in the lining of your gallbladder.
Your gallbladder is a small, pear-shaped pouch in the upper right part of your abdomen (tummy). It stores bile that is produced by your liver. Bile is a fluid that helps break down fatty food. It’s carried from your gallbladder to your bowel through a tube called the bile duct. Bile contains a substance called bilirubin that is yellow-green in colour – it’s produced when red blood cells are broken down in the liver. If bile isn't removed from your blood, it builds up and your skin will turn a yellow colour. This is known as jaundice.
Gallbladder cancer is rare in the UK – just under 800 people were diagnosed with it in 2011. It's more common in countries such as Chile, Japan and India than in European countries.
Gallbladder cancer mostly affects people over 65 but younger people can get it too. It’s more common in women – seven in every 10 people diagnosed with gallbladder cancer are women.
For the majority of people who develop gallbladder cancer, it starts in the cells in the lining of the gallbladder wall. This is called adenocarcinoma. The cancer may spread through the wall of your gallbladder.
You may not have any symptoms during the early stages of gallbladder cancer. Some early-stage gallbladder cancers are found by chance – for example, if a doctor examines your gallbladder after it has been removed to treat gallstones.
Later symptoms of gallbladder cancer can include the following.
These symptoms aren’t always caused by gallbladder cancer but if you have them, see your GP.
The exact reasons why you may develop gallbladder cancer aren't fully understood at present. However, there are some things that may increase your risk of developing it, which are explained here.
Your GP will ask you about your symptoms and examine you. He or she may also ask you about your medical history. Your GP may do a blood test to check your general health and how well your liver is working. He or she may then refer you to another doctor depending on the results and your symptoms. This may be to a gastroenterologist, a doctor who specialises in identifying and treating conditions that affect the digestive system. Alternatively you may be referred to a surgeon.
You may then be offered further tests to find out whether your symptoms are caused by gallbladder cancer or something else. Some of these are explained below.
If you're found to have cancer, other, more specific tests may be recommended to you to find out how advanced the cancer is. This process, known as staging, takes into account whether the cancer has spread and how big it is. You’re likely to be offered a CT scan to do this. This uses X-rays to produce three-dimensional pictures of the inside of your body. The test is painless and only takes a few minutes.
The treatment you’re offered for gallbladder cancer will depend on how advanced your cancer is and your general health. Your doctor will discuss your treatment options with you.
This is the main type of treatment for gallbladder cancer. If your cancer hasn't spread beyond the wall of your gallbladder, you may only need to have your gallbladder removed. This operation is called a cholecystectomy. However, if your cancer has spread to tissues beyond your gallbladder, you will be advised to have these removed with a bigger operation. Other parts of your body that may need to be removed include:
It’s possible that your cancer may have already spread too far to surrounding tissues for it to be possible to remove it with surgery. Instead, your surgeon will aim to relieve your symptoms and prevent jaundice. This is called palliative therapy.
Your surgeon may recommend having a stent (a small, hollow tube) inserted to help bile drain properly into your bowel. Your surgeon may insert the stent through an endoscope or through your skin, passing through your liver.
Alternatively, you may be offered a bypass operation to prevent your bile duct from becoming blocked. In this operation, your surgeon will cut your gallbladder or bile duct above where it’s blocked and reconnect it to your small bowel. This will allow bile to go around and bypass the cancer.
Chemotherapy uses medicines to try to destroy cancer cells. If your surgeon can’t completely remove your cancer, you may be offered chemotherapy to try to shrink it and so reduce your symptoms. This is known as palliative care.
A clinical trial is currently being carried out to test the effectiveness of using chemotherapy after surgery to prevent the cancer coming back. It’s hoped that this may increase the chance of curing gallbladder cancer.
Radiotherapy uses radiation to destroy cancer cells. A beam of radiation is targeted on the cancerous cells, which shrinks the tumour. However, it’s rarely used to treat gallbladder cancer except to try to reduce symptoms if your condition is advanced. You may be offered it in combination with chemotherapy.
Photodynamic therapy is a new treatment that is currently being tested. It involves using a light-sensitive medicine and a laser to destroy cancer cells. However, at the moment there isn’t enough evidence to say whether or not it’s effective at treating gallbladder cancer so it’s very rarely used.
As well as the possible new treatments for gallbladder cancer that are mentioned here, many more are being tested in clinical trials. You may be able to take part in a clinical trial – ask your doctor for more information.
Being diagnosed with cancer can be distressing for you and your family. An important part of cancer treatment is having support to deal with the emotional aspects as well as the physical symptoms. Specialist cancer doctors and nurses are experts in providing the care and support you need, and may also visit you at home. If you have more advanced cancer, further care is available to you in hospices or at home.
