Is brain tumor genetically inherited? Or does it start at sometime later in your life due to whatever reason?

Hi there someone I know had her grandmother pass away because of brain tumor and always complains about sharp headaches and sharp pains in the head and has expressed concern about whether she could have it too because of her grandmother. Could she?

    Normally, brain tumor is not an inherited condition. It is more of a random event.

    Some brain tumors are inherited and some are not. The exact cause of most brain tumors is not known.

    For example, neurofibromatosis is associated with brain tumors that are usually benign.

    Li Fraumeni syndrome is a genetic condition that predisposes people to a number of cancers, including brain tumors.

    There is currently a study going on that is studying familial predisposition to gliomas, a type of brain tumor, I enrolled our family in it.

    I have an interest in this topic as my niece passed away from a malignant brain tumor at age 4. 7 years later my son was diagnosed with a malignant brain tumor, a different type, at age 9. My husband's paternal grandfather passed away from a brain tumor in his 40's. In our case, we suspect a genetic connection but we don't know what it is.

    Most people over the age of 60 who are diagnosed with a brain tumor have glioblastoma, these are not generally considered to be inherited, so this could be the case with your friend's grandmother.

    But any sharp pains and/or headaches should be investigated. It could be migraine, or something as serious as an aneurysm.
