Cancer is an abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize (spread).
Cancer is not a disease. This is a group of more than 100 different and distinctive diseases.
Cancer can affect any tissue in the body and have many different forms in each body part. Most cancers are named for the type of cell or organ in the beginning. If the cancer spreads (metastasizes), the new tumor has the same name as the original (primary) tumor.
The frequency of a particular cancer may depend on gender. Although skin cancer is the most common malignancy in men and women, the second most common type in men is prostate cancer and in women, breast cancer.
Cancer frequency does not equate to cancer mortality. Skin cancers are often curable. Lung cancer is the leading cause of cancer death in men and women in the world today.
Benign tumors are not cancerous, malignant tumors are cancer. Cancer is not contagious.
Cancer is the Latin word for crab. The ancients used the word in the sense of a malignancy, doubtless because of the tenacity of crabs, like a malignant tumor sometimes seems to show in grasping the tissues it invades. Cancer can also be called malignant, a malignant tumor or neoplasm (literally, a new growth).
ORIGIN OF CANCER
All cancers begin in cells, the body's basic unit of life. To understand cancer, it helps to know what happens when normal cells become cancer cells.
The body is composed of many cell types. These cells grow and divide in a controlled manner to produce more cells as needed to keep the body healthy. When cells become old or damaged, they die and are replaced by new cells.
But sometimes this orderly process goes wrong. The genetic material (DNA) of a cell can be altered or changed, producing mutations that affect normal cell growth and division. When this happens, cells do not die when they should, and new cells form when the body does not need. The extra cells can form a mass of tissue called a tumor.

CAUSES OF CANCER
some of the causes of cancer such as smoking, can be controlled. Others, such as a person's age or family history can not be changed.
Causes
Scientists have found many factors that make a person more prone to hepatocellular cancer.
1.Gender
Men are more likely to develop liver cancer than women. This could be due to the following conduct, such as smoking and alcohol abuse.
There are also some inherited liver diseases that increase the risk of liver cancer.
2. Cirrhosis
Cirrhosis (suh-row-sis) is a disease in which liver cells are damaged and replaced by scar tissue. This can often lead to cancer. In this country, the main causes of liver cirrhosis are alcohol abuse and hepatitis B and C. Another cause is a disease that causes too much iron in the liver.
3. Diabetes
Diabetes can increase the risk of liver cancer. This is more common in diabetics who have other risk factors such as alcohol abuse or viral hepatitis.
4. Obesity
Obesity can increase the risk of liver cancer.
5. Aflatoxins
These cancer-causing substances are made by a fungus that can contaminate peanuts, wheat, soybeans, peanuts, corn and rice. The long-term exposure to aflatoxins may increase the risk of liver cancer. In the United States and Europe, these foods are tested for aflatoxins.
6. Vinyl chloride and thorium dioxide (Thorotrast)
These chemicals are risk factors for various types of liver cancer. They have become much less important as Thorotrast is no longer used and vinyl chloride exposure is strictly controlled.
7. Anabolic steroids
These male hormones are used by some athletes to increase strength. The long-term use of these may slightly increase the risk of liver cancer.
8. Arsenic
In some parts of the world, drinking water contaminated with arsenic increases the risk of liver cancer. This is a concern in some areas of the United States.
Less Certain risk factors for liver cancer
Birth Control Pills
Birth control pills may slightly increase the risk of liver cancer. Most studies linking birth control pills and cancer involving the types of pills that are no longer used. Birth control pills are made differently, and it is unclear whether increasing the risk of liver cancer.
Snuff
Some studies have found an association between smoking and cancer of the liver, but the magnitude of this is not known.

HOW TO PREVENT CANCER
Food: Eat organic produce, especially fruits whose peels are eaten, and avoiding red meat. Eat low on the food chain, choosing fresh produce and grains and less meat.
Cleaning products: Look under the kitchen sink, and avoid the use of all that has a skull and crossbones. Buy baking soda and vinegar instead - they are so good.
Cell: Limit calls as much as possible, to reduce the penetration of microwaves directly into your brain.
Nonstick cookware and stain repellents: Discard any old, cracked nonstick pans, because the chemical, PFOA, used to make the nonstick coating has been linked to cancer. It is also presernt in stain-resistant clothing, and waterproof fabrics. Rain gear-testing is good, but not next to the skin.
Personal care items: Avoid anything that contains parabens - butylparaben, methylparaben - some studies have shown estrogenic activity and have also been found in human breast tumors.
