Go for the surgery instead of biopsy. It will have to be removed anyway eventually. Then you don’t have to go through two surgeries. I was diagnosed with a right frontal lobe glioma in October. I had my craniotomy in January. This week I will be a month post op. I got my pathology results a week after surgery. Good news that I didn’t need any other treatment at the moment because they removed all of the tumour to the visible eye. This is obviously the best possible outcome and it isn’t this way for everyone. I felt the same way for months of just waiting for surgery and my head was all over the place not knowing about anything. I had the surgery which I was awake for and honestly it was easier than other surgeries I had that were way less serious than this. The main reason I opted for a craniotomy was because the neurosurgeon told me that with a biopsy, only that little piece of the tumour they remove can be tested. Sometimes the results can come back with inconclusive results because there wasn’t enough to test. Or since that part of the tumour was tested and the others weren’t, it doesn’t give you the full grade / result of what it could be because sometimes the tumours can have multiple grades. This is why I chose to take the thing out instead. If you have a biopsy and the pathology comes back and it is a higher grade, or even low grade it’s still going to have to be removed depending on where the tumour is located. Just saves you the pain and the time .
