WHAT CAUSES CANCER
- Cancer starts when cells in a part of the body start to grow out of control.
- Smoking is the most preventable cause of tumor.
- Cancer cell growth is different from normal cell growth.
- Instead of dying, cancer cells continue to grow and form new, abnormal cells.
- Cancer cells can also invade (grow into) other tissues, something that normal cells cannot do.
- Growing out of control and invading other tissues are what makes a cell a cancer cell.
- Cells become cancer cells because of damage to DNA.
- the damaged DNA is not repaired, but the cell doesn’t die like it should.
- Instead, this cell goes on making new cells that the body does not need. These new cells will all have the same damaged DNA as the first cell does.

- ...theoretically the risk for a smoker to get cancer is 23 times higher than for a non-smoker
- ...that scientists found a note from 1600 B.C. that seemed to deal with cancer without using this word though
