I have a brain tumour and I'd like an opinion on...?

I was wondering if surgery would be the best way to get it out? I've been with chemotherapy for a while - small amount of shrinking was the result. They've suggested I go with surgery to remove what's left because it has shrunk it slightly. It hasn't spread - and I'm not sure if it even can. It's malignant. Would radiotherapy be another better option? If I were to get surgery to remove it, would anyone know what they'd do ? I'm not so sure about the surgery option - a bit worried. Sorry if I make no sense D: I'd like some good opinions please
