Is Brain Cancer the same as a Brain tumor?

No, but a brain tumor is cancerous, just not quite the same. I hope you don't mind, but I have a story to tell you. My mom had a brain tumor, it was the size of an orange. I don't remember it because I was maybe 4. The operation to remove it took maybe 4 hours, and she is fine now, but has lost a little bit of memory, like math and science. Anyways, a brain tumor is abnormal development of tissue that squishes your brain and can kill you easily. Brain cancer is when cells in your brain begin to grow out of control because those cells have DNA damage and when they make another through asexual reproduction, the new cell has DNA damage. The roundup: My mom had a brain tumor when I was around four; A brain tumor and brain cancer are both cancerous but different because a brain tumor is excessive growth of tissue; brain cancer is when a damaged cell in your brain reproduces asexually and keeps reproducing until there are too many damaged brain cells.
Hope I helped! :)
