My husband had very few symptoms and no headaches but a CT scan showed a ring enhanced brain lesion that was biopsied and it was a glioblastoma multiforme (brain cancer) my advice is to get the biopsy and stop it early
I am still waiting myself....it doesn't seem so. You cant even ask the doctor here, everytime I go online a message says the quota has been reached. Looks like it's only a few times a month that a question can be posted.
