'affected areas'

Cancers that are known collectively as head and neck cancers usually begin in the squamous cells that line the moist, mucosal surfaces inside the head and neck (for example, inside the mouth, the nose, and the throat). These squamous cell cancers are often referred to as squamous cell carcinomas of the head and neck. Head and neck cancers can also begin in the salivary glands, but salivary gland cancers are relatively uncommon. Salivary glands contain many different types of cells that can become cancerous, so there are many different types of salivary gland cancer. Cancers of the head and neck are further categorized by the area of the head or neck in which they begin. These areas are described below:- 1. Oral Cavity: Includes the lips, the front two-thirds of the tongue, the gums, the lining inside the cheeks and lips, the floor (bottom) of the mouth under the tongue, the hard palate (bony top of the mouth), and the small area of the gum behind the wisdom teeth. 2. Pharynx: The pharynx (throat) is a hollow tube about 5 inches long that starts behind the nose and leads to the esophagus. It has three parts: the nasopharynx (the upper part of the pharynx, behind the nose); the oropharynx (the middle part of the pharynx, including the soft palate [the back of the mouth], the base of the tongue, and the tonsils); the hypopharynx (the lower part of the pharynx). 3. Larynx: The larynx, also called the voicebox, is a short passageway formed by cartilage just below the pharynx in the neck. The larynx contains the vocal cords. It also has a small piece of tissue, called the epiglottis, which moves to cover the larynx to prevent food from entering the air passages. 4. Paranasal sinuses and nasal cavity: The paranasal sinuses are small hollow spaces in the bones of the head surrounding the nose. The nasal cavity is the hollow space inside the nose. 5. Salivary glands: The major salivary glands are in the floor of the mouth and near the jawbone. The salivary glands produce saliva.

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.

Prostate cancer is the most common type of cancer found in men and usually begins without symptoms. The chances of surviving prostate cancer are greatly improved with early detection and treatment. At UCLA we offer the entire spectrum of treatment options including, but not limited to, nerve-sparing radical prostatectomy, robotically-assisted laparoscopic prostatectomy, laparoscopic prostatectomy, brachytherapy, cryotherapy and active surveillance, as well as offering Targeted Prostate Biopsy using MR-Ultrasound Fusion to diagnose prostate cancer. Almost all prostate cancers are adenocarcinomas. These cancers develop from the gland cells (the cells that make the prostate fluid that is added to the semen). 1. Sarcomas 2. Small cell carcinomas 3. Neuroendocrine tumors (other than small cell carcinomas) 4. Transitional cell carcinomas These other types of prostate cancer are rare. If you have prostate cancer it is almost certain to be an adenocarcinoma. Some prostate cancers can grow and spread quickly, but most grow slowly. In fact, autopsy studies show that many older men (and even some younger men) who died of other causes also had prostate cancer that never affected them during their lives. In many cases neither they nor their doctors even knew they had it.
