Is Glioblastoma Hereditary
Glioblastoma is the unnatural, uninhibited overgrowth of certain supportive cells in the brain (not the nerve cells themselves). Like other cancers, this can destroy good cells, often by pressure within the space of the skull. Unfortunately, it weaves its way between good brain cells and the limits of the growth usually cannot be known with certainty. That's why surgery alone ...Read more

Mom died of glioblastoma after lifetime of good health. Can it be hereditary? Her surgeon and neuro-onc said it is very rare and happens at random.
I agree: We are not aware why some folks get these nasty brain tumors, and why they transform as they do. Very rare to have familial genetics that cause this, and agree that there is no reason to worry, as this is most likely a matter of chance, and rather remote odds. ...Read moreSee 1 more doctor answer

Why are glioblastomas so common and is there anything a person can do to reduce the chance of getting one ?
Uncommon cancer: You have misunderstood something you read. Glioblastomas are relatively uncommon cancers, with about 12,000 new cases each year in the entire US. Not exactly rare, but that's 20 times and 15 times less common than breast cancer and prostate cancer, respectively. Most other cancers also are more common than glio. There is no known prevention against glioblastoma, so good thing it's pretty rare! ...Read more
Tumor grading: Grading of tumors is a way of "standardizing" the type of cancer, and thereby improving consistency of treatment between treating doctors/institutions. In gliomas as in other sites, a higher grade also implies a more aggressive tumor and potentially a poorer prognosis. However, some high grade tumors can be curable, whereas low grade tumors tend to linger but not respond to treatments. ...Read moreSee 2 more doctor answers
Depends: This is difficult to answer. Glioblastoma is a very malignant tumor and very difficult to treat. The smaller the tumor the better the chances of "success " in treating the tumor with radiotherapy. Surgery also an option if again it is a small lesion. Unfortunately often times diagnosed at a late stage. ...Read more
