    What happens to the cells (in the brain) as a cancerous tumor is formed? What are the stages - from stage 1 onwards- how cells go from being healthy and regular to being damaged (resulting in a tumor)? Keeping in mind that this is a tumor formed in the brain and not cancer spread from another part of the body.
    In addition - Are there any helpful medical sources which offer a clear explanation on this.

    Thank you.

    This mechanism is not known; there are no dysplastic pre-neoplastic stages known for primary brain tumors.

    however there are genetic associations which lead to brain tumors.

    EDIT: oops this is being discussed in biology anyway!
