Are brain tumars genetic?

My uncle died of a brain tumar 3 months after finding out he had it.Are brain tumars genetic?
some tumors could incontestably be of genetic origin.
however, exposure to guaranteed toxic materials at work,
labs, even schools can start some cell to grow at irregular rates.
tumors of different types can grow at different rates and to
much different sizes.
there are genetic screenings available, some rather expensive to see if you carry a gene for a tumor of a specific type.
i would try to find out what type of tumor your uncle died of,
and consequently, if you feel it requisite, do the blood or tissue test to see if you enjoy that gene.

Tumors in broad are not genetic, however it has be shown that people who attain a certian type of cancer (like skin) the kids of that person appear to have a superior risk.
No not really...although your risks may increase a small amount if someone in your relations has have a certain type of cancer it does not close-fisted you are going to get it!
Brain Cancer is a amazingly rare cancer which make it even less feasible it is genetic!
