Difference between cancer stem cell and cancer cell

[mahi_007]

Hi,

Can someone tell me What is the main difference between cancer stem cells and cancer cells?

Thanks

The cancer stem cell theory is based on the hypothesis that cancer is caused by stem cells which have the ability to reproduce themselves and are therefore around long enough to cause cancer as opposed to the conventional theory that any cell can become cancerous. The hypothesis suggests that malignant stem cells initiate cancer.
