'protecting healthy tissues'

Primary liver cancer is a condition that happens when normal cells in the liver become abnormal in appearance and behavior. The cancer cells can then become destructive to adjacent normal tissues, and can spread both to other areas of the liver and to organs Malignant or cancerous cells that develop in the normal cells of the liver (hepatocytes) are called hepatocellular carcinoma. A cancer that arises in the ducts of the liver is called cholangiocarcinoma. Liver cancer begins in the tissues of the liver, an organ that sits in the upper right portion of the abdomen, beneath the diaphragm and above the stomach. The liver has many functions. It helps store nutrients from food, aids with digestion and clears toxins from the body. You cannot live without your liver. It has several important functions:- 1. It breaks down and stores many of the nutrients absorbed from the intestine that your body needs to function. Some nutrients must be changed (metabolized) in the liver before they can be used for energy or to build and repair body tissues. 2. It makes most of the clotting factors that keep you from bleeding too much when you are cut or injured. 3. It secretes bile into the intestines to help absorb nutrients (especially fats). 4. It breaks down alcohol, drugs, and toxic wastes in the blood, which then pass from the body through urine and stool

Tumors of soft tissue are more common than bone tumors. They can occur almost anywhere: within and between muscles, ligaments, nerves and blood vessels. These tumors vary widely in how they look and behave. Some can be quite aggressive. The more the tumor has invaded nearby tissues, the harder it is to completely remove. This, in turn, increases the chances that the tumor will come back. A sarcoma is a type of cancer that develops from certain tissues, like bone or muscle. Bone and soft tissue sarcomas are the main types of sarcoma. Soft tissue sarcomas can develop from soft tissues like fat, muscle, nerves, fibrous tissues, blood vessels, or deep skin tissues. They can be found in any part of the body. Most of them develop in the arms or legs. They can also be found in the trunk, head and neck area, internal organs, and the area in back of the abdominal cavity (known as the retroperitoneum). Symptoms Signs of a benign soft tissue tumor vary widely. If they are close to the surface of the body, they may appear as a lump. Some cause pain; others don't. They vary widely in how they look as well. If you have pain or if the tumor grows, you should see a doctor. 1. Lipomas, benign tumors composed of fatty tissue 2. Angiolipoma 3. Benign fibrous histiocytoma 4. Neurofibroma 5. Schwannomas 6. Hemangiomas, noncancerous tumors that are formed by a mass of blood cells. The tumor rarely become malignant, and can be successfully excised. They often result from trauma to the affected part. 7. Benign fibrous histiocytoma Smoking: Smoking tobacco is an important risk factor for kidney cancer. People who smoke have a higher risk than nonsmokers. The risk is higher for those who smoke more cigarettes or for a long time. High blood pressure: Having high blood pressure may increase the risk of kidney cancer.
