A question about brain cancer?

It's quite obvious someone is lying. I had brain cancer so I know a thing or twelve. If someone has brain cancer, you can pretty much bet they would be in hospital for about a week and come out with a Frankenstein cut on their head, with the hair shaved gone where the incision was. After a month of healing, 2 weeks after sutures are removed, the person would begin chemo and radiation and would have big bald patches where the radiation pes thru the head. The pain shortly after getting out of the hospital would be bad enough to warrant dr giving you dilaudid for pain, wicked stuff. Mri is used when checking on progress of treatments and for regrowth afterward. And anyone with any sense would know no cancer shows up and disappears and shows up at random. Don't even get me started on the chemo brain, the numbness in your hands and feet, the twitches in your face, all after treatment.
