I have always been worried about Astrocytoma being hereditary! Simply because, when I was 12 years old I was diagnosed with an Astrocytoma brain tumor in the third ventricle. They way they found it was that I was having headaches and double vision. I went to the eye Dr thinking I needed glasses, and when the Dr looked in my eye he could see something but couldn't tell what it was. So my mom took me to my pediatrician and they could see it too. Then they sent me to Children’s Hospital in Cincinnati were they did a MRI. Later that day is when they told me they thought I had an assist. And they told me that I needed to have surgery ASAP. I was very lucky to have the Dr I had, his name is Dr. Kerry Crone AKA the Miracle Doctor (look him up) Then about a year later the tumor came back and he had to take it out again. My grandfather died of the same tumor I had because his was in the cerebellum (in the back of the brain) One day he was driving down the road and blacked out and got in an accident and left the scene to go home. Later that day the police showed up and asked him if he was in a accident and of course said "No" so they looked in the garage and sure enough he was. So they took him to the hospital and that’s where they found it. They gave him 6-12 months to live and he lived seven years. I am now 30 years old with 4 wonderful kids and it’s been 17 years since my last surgery and I am very thankfull for everything and especially for Dr. Kerry Crone MD. I have done some research on Astrocytoma and have not found any evidence of it being hereditary.
Astrocytoma is common type of glioma which occur in astrocytes cells of the brain and occasionally in spinal cord. This tumor can be benign or malignant. Exact etiology of the astrocytomas is not known but factors like heredity, occupation, viruses and environmental factors can play their role. So, it is not necessary that your son or grandson should have this type of brain tumor. You should look for the symptoms like headache, nausea, vomiting, sezieres, changes in vision, walking problems and problems with memory. If you find any these symptoms in your sons and grandsons then go for MRI or CT scan to conform the diagnosis.
