The liver is the largest organ in the body, and the main heat-producing organ. It is surrounded by a fibrous capsule and is divided into sections called lobes. It is in the upper part of the abdomen on the right-hand side of the body and is surrounded and protected from injury by the lower ribs.
The liver is an extremely important organ that has many functions. This includes producing proteins that circulate in the blood. Some of these help the blood to clot and prevent excessive bleeding, while others are essential for maintaining the balance of fluid in the body.
Radiofrequency ablation procedure, electric current in the radiofrequency range is used to destroy malignant cells. Using an ultrasound or CT scan as a guide, your surgeon inserts several thin needles into small incisions in your abdomen. When the needles reach the tumor, they're heated with an electric current, destroying the malignant cells. Radiofrequency ablation is an option for people with small, unresectable hepatocellular tumors and for some types of metastatic liver cancers. Although the procedure has a somewhat higher risk of serious complications than alcohol injection does, it appears to provide better outcomes.
On the day of treatment, the patient is given a mild sedative and pain medication. The radiologist makes a tiny incision in the groin—no larger than the tip of a pencil—to gain access to the femoral artery. Using moving X-ray images (fluoroscopy) as a visual guide, the physician directs a thin, flexible tube (catheter) through the artery and into the main blood vessel feeding the liver tumor. The radioactive beads are injected and carried in the bloodstream up to the tumor, where they embed and slowly kill the cancerous cells.
Surgery is increasingly being used for patients with secondary liver cancer. This can sometimes involve removing a segment of liver. Alternatively, keyhole techniques can be used to apply extreme cold or heat to localized areas of the liver.
The presence of secondary cancer within the liver implies that the primary tumor has spread via the bloodstream and as a result other organs may be at risk.
Hepatocellular cancer is more likely to develop in people with chronic cirrhosis. Your specialist may suggest a liver transplant if you have cirrhosis of the liver because of previous liver disease, infection with a hepatitis virus or from drinking alcohol. You will only benefit from a liver transplant if you have a single liver tumour that is less than 5cm across, or up to 3 tumours all less than 3cm across. There is an added difficulty of having to wait for a suitable donor. This can take months. During this delay, the cancer will continue to grow and you have other treatment to try to control it.
Radiation Exposure can lead to liver sarcomas, sometimes as long as 5 decades after the exposure. The common thread to liver cancer risk factors is chronic irritation, which causes the liver cells to divide more quickly than they ordinarily would to repair perceived damage. The more often cells divide, the more the chance for a genetically abnormal one to arise, with the gene changes leading to its becoming cancerous.
