Liver Cancer Treatment at World Class Cancer Hospitals in India
The Liver continuously filters blood that circulates through the body, converting nutrients and drugs absorbed from digestive tract into ready-to-use chemicals. The liver performs many other important functions, such as removing toxins and other chemical waste products from the blood and readying them for excretion. Because all the blood in the body must pass through it, the liver is unusually accessible to cancer cells travelling in the bloodstream.
When cancer develops in the liver, the cells change and grow in an abnormal way. As the cancer grows it forms a group of cells called a tumor. This tumor can cause a blockage and result in symptoms like pain and jaundice. When cancer starts in the liver, it is called primary liver cancer. But when cancer starts somewhere else in the body and spreads to the liver, it is called secondary liver cancer.
Two Major Types of Liver Cancers are:
Primary liver cancer begins in the liver itself. Although it’s less commonly seen than secondary liver cancer, primary liver cancer rates are on the rise in the United States.
Primary liver cancer is most commonly caused by Hepatitis B and C, diseases that affect the blood and, in turn, cells called hepatocytes, which are the main type of liver cell. These diseases can be contracted from a variety of sources, including sexual or blood-borne contact. This form of cancer is called hepatocellular carcinoma. It is the most common type of liver cancer throughout the developing world.
Secondary (metastatic) liver cancer is a type of cancer that has spread to the liver from another area in the body. In the United States, this type of cancer is more common than primary liver cancer.
About 50 percent of all metastatic liver cancer spreads from the colon to the liver. (Fortunately, sometimes surgery can be offered when the cancer has only spread to the liver.) Cancer also can spread to the liver from cancer of the breast, ovaries, pancreas, lungs, and other places.
The liver is particularly susceptible to the spread (metastasis) of cancer because of the liver’s role as the body’s filter. All blood in the body passes through the liver at some point. To accomplish this, two major blood supply vessels go to the liver, the hepatic artery and the portal vein. Because of the rich supply of blood and constant circulation, the liver has an increased chance that diseased cells will pass through it and take hold.
Diagnosis of Liver Cancer
- Blood Tests.
- Computed Tomography (CT) Scan.
- Magnetic Resonance Imaging (MRI).
- Liver Biopsy.
- Needle Biopsy.
- Large Core Needle Biopsy.
Treatment Options available for Liver Cancer Treatment at World Class Hospitals in India
Surgery to Remove the Tumor.In certain situations, your doctor may recommend an operation to remove the liver cancer and a small portion of healthy liver tissue that surrounds it if your tumor is small and your liver function is good.
Whether this is an option for you also depends on the location of your cancer within the liver, how well your liver functions and your overall health.
Liver Transplant Surgery. During liver transplant surgery, your diseased liver is removed and replaced with a healthy liver from a donor. Liver transplant surgery is only an option for a small percentage of people with early-stage liver cancer.
1. Chemotherapy may be used before surgery to destroy cancer cells. It also allows your oncologist to determine the effects of a particular liver cancer treatment regimen on the tumor.
2. Chemotherapy is used after surgery or radiation to target cancer cells that were not removed during liver cancer surgery, and helps prevent the cancer from spreading to other parts of your body.
3. Systemic chemotherapy, meaning the circulation of chemotherapy drugs through the bloodstream to cancer cells through the body, plays an important role in the treatment of locally advanced or metastatic primary liver cancer.
Another option for tumors that cannot be surgically removed is treatment with high-energy rays or radiation therapy. Radiation can be given externally from special equipment that positions the patient and delivers doses of radiation from the outside of the body to very precisely target internal cancer cells. The primary goal of this treatment is the relief of symptoms.
Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist.
