Cancer cells are more easily damaged by radiation than normal cells because they are:
Cancer cells are more easily damaged by radiation than normal cells because they are:
starved of mutation
undergoing rapid division
different in structure
non-dividing.
Solution
Cancer cells multiply faster than normal cells in the body. Because radiation is most harmful to quickly growing cells, radiation therapy damages cancer cells more than normal cells. This prevents the cancer cells from growing and dividing, and leads to cell death.

Characteristics of cancer cells
- Uncontrolled potential to divide and do not response to programmed cell death, or apoptosis.
- Show Metastasis i.e., they can migrate and spread to other organs and tissues by travelling through the bloodstream.
- Angiogenesis is the formation of new blood vessels from existing blood vessels to meet their high oxygen demand.
- shows chromosomal abnormalities
