Brother in law had a non cancerous brain tumor (vestibular schwannoma) removed last year. The sucker had been growing for an estimated 10 years and was too large to treat with anything other than surgery. While the surgery was considered successful, they had to leave more of it in there than planned. They monitored it for a while as there was the possibility that it might stop growing, but no luck there. On the up side, it was now small enough for radiation. He just completed 4 weeks of it and feels like death, most food tastes awful, severe fatigue.
He had an appointment with the ENT who was part of the surgery team a few days after the radiation, goes over the radiation treatment notes and loses his shit. It turns out that they gave him too high a dose and did too many sessions. They had also told him that because he had already had brain surgery, treating the tumor with more precise radiosurgery was off the table, which he had never head before. He's going to get in touch with his neurosurgeon and plans to raise hell with the office that did the radiation. While I'm glad about that, where the fuck does that leave the patient? While he's glad to still be alive, his life has been pretty fucking miserable the last few weeks because of this.
