For decades, liquid air, carbonic snow and iced saline solutions were used to destroy advance malignancies for palliative purposes [5]. Now, there is a significantly increasing demand for novel, minimally invasive treatments as the need for tumour detection rises. When surgery is not feasible, other therapeutic alternatives including chemotherapy, thermal ablation, systemic therapies and intra-arterial interventions are used [6]. Unfortunately, no systemic therapy has been proven effective. While chemotherapy and RFA have shown to relieve pain, decrease liver size and improve liver function tests, it also affects the normal liver as well as tumorous tissues, limiting their usefulness [5].

It has been shown that the blood vessels of tumour are more sensitive to heat than normal vasculature [8]. A study carried out by Zhao et al. demonstrated the heating effect of thermal significant blood vessels in CA [9]. Further research has been done on the effects of large blood vessels on the transient temperature field during CA for four different arrangements between tumour and blood vessel [10]. Wang et al. in their study coupled the heat transfer and fluid flow model established in a three-dimensional space consisting of tumour, normal tissue and vascular network [8] . This model was used to predict the effect of vascular network on IIF, tumour destruction and thermal history during treatment. The numerical approaches to the multidimensional freezing problem during CA may generally be divided to the finite difference method (FDM) and the finite element method (FEM). A comparison done showed that FEM is more suitable for irregular boundaries which is often the case for tumour tissues [9] . For example, Zhang et al. generated a three-dimensional model directly from the MRI images of a real prostate which was analysed using FEM to predict heat transfer in prostate cancer CA [11].

"Cancer of the pancreas is a genetic disease that is the fifth most common cause of death in both men and women. Pancreatic cancer affects approximately 28,000 Americans each year, or five out of 100,000 people" (Mayo Clinic, 1998). According to physicians at Johns Hopkins Medical Institute, "pancreatic cancer is the challenge of the twenty-first century." So, where exactly is the pancreas located in our bodies, and what does it do? The pancreas is a gland found behind the stomach that is shaped somewhat like a fish. The pancreas is about six inches long and less than two inches wide, and it extends across the abdomen. The pancreas consists of two separate glands inside the same organ, the exocrine gland and the
Stomach cancer, also known as gastric cancer, is a type of cancer that develops slowly over many years. Most frequently, stomach cancer starts in the lining of the stomach otherwise knows as the mucosa, and then develops into the other layers of the stomach. There are many ways in which stomach cancer spreads. In some cases it invades near by organs or it can also travel through the bloodstream to for cancer in other organs. There are many statistics and organizations of support for stomach cancer, as well as, symptoms, risk factors, screening and diagnosis’ and, treatments. Like all cancers, stomach cancer is a deathly disease and one of the major leading causes of cancer deaths in countries other than the U.S.
Your kidneys are two bean-shaped organs, each about the size of your fist. They're located behind your abdominal organs, one on each side of your spine. Like other major organs in the body, the kidneys can sometimes develop cancer. Your kidneys are part of the urinary system, which removes waste and excess fluid and electrolytes from your blood, controls the production of red blood cells, and regulates your blood pressure. Inside each kidney are more than a million small filtering units called nephrons. As blood circulates through your kidneys, the nephrons filter out waste products as well as unneeded minerals and water. This liquid waste — urine — flows through two narrow tubes (ureters) into your bladder, where it's

Cirrhosis is a serious disease of the liver where scar tissue replaces normal healthy tissue, and affects the function and structure of the liver. Liver, which is the largest organ in the body, has a vital roles which are important to keep the body functioning well. Liver makes proteins and enzymes that regulate blood clotting. It also regulates cholesterol and stores the energy. In addition, the liver removes poisons from the blood. 30% of cirrhosis's victims are diagnosed will remain alive for 5 years. Cirrhosis can be defined regarding its causes, symptoms, diagnosis, and treatment.
Cirrhosis is the eighth leading cause of death in the United States and the thirteenth leading cause of death worldwide.1 Cirrhosis is the irreversible fibrosis of the liver characterized by hepatic architectural distortion secondary to fibrous tissue and the formation of regenerative nodules.2 These anatomical changes cause hepatic vascular resistance and an increase in blood flow leading to portal hypertension. Porto-systemic collaterals develop in order to overcome the increased portal pressure gradient.3 Nitric oxide, an endogenous vasodilator is also released in effort to overcome portal pressure with the expense of causing systemic vasodilation and a decrease in blood pressure. As a result, a marked activation of neurohumoral vasoactive factors occurs in an effort to maintain an effective arterial blood pressure. Hypervolemia, increased cardiac index, decreased systemic vascular resistance, and systemic hypotension are manifestations of portal hypertension.3 Chronic hepatitis B virus (HBV), hepatitis C virus (HCV), alcoholism, nonalcoholic steatohepatitis (NASH), and non-alcoholic fatty liver disease (NAFLD) are all major causes of cirrhosis.
Malignant Hyperthermia is a life-threatening, genetic disorder that involves the skeletal muscles. It commonly occurs intraoperatively and postoperatively when inhalant agents such as halothane, enflurane, and isoflurane are used, as well as some muscle relaxants such as succinylcholine and curare.

There are over 100 types of cancer. One type is called colon cancer, a very common disease in the lower part of the digestive system. Colon cancer is luckily very treatable if caught early, but because it is so common it is the second leading cause of death from cancer. About 140,000 people in the U.S. are diagnosed with colon cancer every year.
There are different types of cancers. There is Leukemia, Breast cancer, Throat Cancer, and more. Then, theres the cancers that not a lot of people think about. Cancers that exist, but are unknown to most people. They are very rare and not a lot of people have it, but it’s still there affecting people in the same ways, even worse, that any known cancer affects people. One of the is Central Nervous System AT/RT Cancer.
Liver cancer is in the top ten for most alarming cancers. It is placed in the abdominal cavity. Also it is placed to the right of the stomach under the diaphragm. A average adult liver receives about two quarts of blood every minute and weighs around three pounds. The biggest glandular organ in the body is the liver and it keeps damaging substances and toxins out of the body. The liver is an critical organ in our body because it stocks vitamins, iron, and sugar glucose. It produces bile which is a substance to digest fats and it destroys old RBC. Also the liver detoxifies the blood to rid it of damaging substances such as drugs and alcohol and breaks down hemoglobin as well as insulin and other hormones. Lastly the liver alters ammonia to urea,
Cancer is a disease in which cells multiply out of control and gradually build a mass of tissue called a tumor. There has been a large amount of research dedicated to the treatment and cure of cancer. Several types of treatments have been developed. The following are just some of the major examples of cancer therapy: surgery, chemotherapy, radiation therapy, biologic therapy, biorhythms, unconventional treatments, and hyperthermia. Each type of treatment is discussed in detail below.
This report will discuss how liver cancer affects the liver. I will discuss the how liver cancer affects the normal operation of the liver, what causes liver cancer, how this cancer can be detected and how this cancer can be treated. I will conclude with a discussion of how common liver cancer is.
Hepatitis C has been referred to as a "Silent Epidemic," since it usually progresses slowly over many years. Most people who are infected with hepatitis C are not aware of any noticeable symptoms for as long as one to two decades after they are infected. In fact, by the time symptoms appear, the virus has probably already begun to damage the liver. If the liver is injured and stops functioning, death will always be the outcome (Lieber). Liver failure from chronic hepatitis C is one of the most common causes of liver transplants in the United States.

The Liver is the body's largest gland, weighing about three to four pounds. It is located beneath the diaphragm in the right upper quadrant (RUQ) of the abdominal cavity. Without the liver, our bodies would be poisoned and unfit for us to do anything at all. It is a metabolically active organ responsible for many vital life functions. The primary functions of the liver are: Bile productions and excretion. Excretion of bilirubin, cholesterol, hormones, and drugs. Metabolism of fats, proteins, and carbohydrates. Enzyme activation. Storage of glycogen, vitamins, and minerals. Synthesis of plasma proteins, such as albumin, and clotting factors. And blood detoxification and purification.
