What is cancer?

The body cells grow, divide to create new cells, and die in an orderly manner. But cancer cells are different. Instead of dying, cancer cells continue to grow into new abnormal cells with no function. These cells proliferate out of control of the body and invade nearby tissues.

On the other hand, cancer cells often go to other parts of the body - where they can develop and form new tumors - through blood or lymph. This process is called metastasis. People with cancer die because tumors thrive and paralyze organs and affect neighboring organs, the body is exhausted, painful, helpless against other diseases.

- Excessive alcohol use causes liver and gastrointestinal cancer.

- Most skin cancers are the result of direct exposure to UV rays in sunlight

- Radiation includes x-rays, gamma rays, ultraviolet rays . agents that cause thyroid and bone marrow cancer.

- Virus and bacteria: Viruses HPV and cervical cancer, hepatitis B and C virus can cause liver cancer, Epstein-Barr virus causes lymphoma, Helicobacter pylori (Hpylori) increases cancer risk stomach.
