Cancer is a disease that attacks the nearby biological tissue where the cells have lost normal control mechanisms, so that. cell cycle that grows out of control (cell division beyond the normal limit). Due to migrate to other body tissues through the bloodstream or lymphatic system, called metastasis. So why the disease is called malignant neoplasm or malignant disease.

There are various types of cancer that attacks the human body. Cancer is one of the leading causes of death in the world. In general, cancers are cited according to the organ or cell type of the place. For example, cancer that begins in the colon is called colon cancer, while cancer that occurs in the basal cells of skin is called basal cell carcinoma. Cancer classification is then performed on the more general category.

- Prostate cancer
Prostate cancer is cancer that develops in the prostate, a gland in the male reproductive system. This occurs when prostate cells mutate and begin to grow out of control.

Causes of cancer
Many studies are conducted to find the cause of this frightening disease.

• Heredity
If one family member had cancer, most likely the offspring will get the cancer cells. But if she lived a healthy lifestyle, the cancer cells will not grow and he can avoid the disease.

• Chemicals
Now many manufacturers of chemicals around the world who produce drugs, plastics, fertilizers, pesticides, and others. These chemicals become one of the biggest causes of cancer. Also the smoking habit can also cause cancer.

• Radiation
In the early 20th century found that people who work in places that are often affected by exposure to radiation, can be affected by cancer, ranging from skin cancer to blood cancer leukemia.

• Viral and bacterial infections
In 1910, discovered the virus that causes cancer in chickens. The first virus found to cause cancer in humans known as HTLV1. In addition the HIV virus is also widely found in humans undergoing free sek. Hepatitis B causes liver infection.
After knowing the definition of cancer and its causes you can control the causes of cancer so as to avoid this dangerous disease.
