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 diseases and distinct.
Cancer may involve the tissue in the body and has a wide range of each region of the body. Most cancers are named after the cell or an organism where to start. 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 cancer in men and women, the second most common type among men is prostate cancer and breast cancer in women.
The frequency of cancer does not mean that cancer mortality. Skin cancer is often curable. Lung cancer is the leading cause of cancer death for 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 to indicate a malignant tumor, no doubt due to the crab's tenacity a malignant tumor sometimes seems to appear to understand the tissue it penetrates. Cancer can also be called malignancy, a malignant tumor or neoplasm (literally, the new growth).
ORIGIN OF CANCER
All cancers begin 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 process goes wrong axis. The genetic material (DNA) in a cell may be damaged 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 them. The extra cells can form a mass of tissue called a tumor.

The causes of cancer
Some causes of cancer, such as smoking, can be controlled. Others, like the story of an aged person or family, can not be changed.
Cause
Researchers have found many factors that make a person more susceptible to hepatocellular liver cancer.
1. Gender
Men are more likely to have liver cancer than women. This may be because of the acts listed below, such as smoking and alcoholism.
There are also some hereditary diseases of the liver, which increases the risk of liver cancer.
2. Cirrhosis
Cirrhosis of the liver (Suh-row SIS) is a disease in which cells are damaged liver and replaced by scar tissue. This can often lead to cancer. In this country, the main causes of cirrhosis are alcohol abuse and hepatitis B and C. The second reason 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 risk factors such as alcohol abuse or viral hepatitis.
4. Obesity
Obesity may increase the risk of developing liver cancer.
5. Aflatoxins
These carcinogens are made from a fungus that can contaminate peanuts, wheat, soybeans, peanuts, corn and rice. Long-term exposure to aflatoxins may increase the risk of liver cancer. In the United States and Europe, these foods are tested for aflatoxin.
6. Vinyl chloride and thorium dioxide (Thorotrast)
These chemicals are risk factors for different types of liver cancer. They have become much less important since Thorotrast is no longer in use and exposure to vinyl chloride is tightly controlled.
7. Anabolic steroids
These male hormones are used by some athletes to increase strength. Prolonged 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 involve types of pills that are no longer used. Birth control pills are made differently, and do not know if they increase the risk of liver cancer.
Tobacco
Some studies have shown the connection of smoking and liver cancer, but the extent is unknown.
NOTE SYSTOMS CANCER
Local symptoms, Unusual lumps, Swelling, Bleeding / hemorrhage, Pain, Ulcers, Jaundice, Systoms systemic, Weight Loss, Lack of appetite, Fatigue, Cachexia (weight loss, muscle atrophy, fatigue, weakness and significant loss of appetite), Excessive sweating, Night sweats, Anemia, Thrombosis, Hormonal changes
How to prevent cancer
Power: Eat organic food, especially fruits whose peels are eaten, and avoid red meat. Eat down the food chain, choosing more fresh produce and grains and less meat.
Cleaning products: Look under the kitchen sink, and avoid using anything with a skull and crossbones. Buy baking soda and vinegar instead - they are just as good.
Cell Phones: Limit your calls as much as possible to reduce the penetration of microwaves directly into your brain.
Non-stick cookware and stain repellents: Delete all the old, broken-stick frying pans, such as chemical, PFOA, used for non-stick coating is linked to cancer. And 'presernt also stain clothing and waterproof fabrics. Waterproof gear is OK, but not against the skin.
Personal care items: Avoid anything that contains parabens - butylparaben, methylparaben - some studies have shown that the estrogenic activity, which is also found in human breast tumors.
