    develop into cancers. Unlike normal genes‚ which can be turned off after being turned on‚ oncogenes are altered in a way that keeps them stuck in a state of constant activity. That uninterrupted action helps drive the uncontrolled growth that underlies tumors. Oncogenes can be turned on by inherited changes - ones that are passed down from parent to child - or by cancer-promoting agents that damage DNA throughout an individual’s lifetime‚ such as UV light‚ hazardous chemicals and even viruses.

A single gene mutation is all that is necessary to drive the cancer cells to grow and divide uncontrollably. As this occurs the body cells go into apoptosis; if the patient does not take the necessary steps for immediate

    Considering the differences between a benign tumor and a malignant tumor‚ why might a benign tumor be easier to treat? benign tumors do not metastasize to other parts of the body but the malignant tumors do.
