Morning all! My dad was recently diagnosed with stage IV small cell lung cancer with metastasis to the brain. They were able to remove most of a very large brain tumor and want to follow up with radiation to his brain before starting chemo for his lungs and lymph nodes. He is on board and willing to fight, but he is struggling with the idea of whole brain radiation. Due to the aggressive nature of small cell, it's imperative that all cells in his brain are targeted. He feels like this method could 'fry' his brain and he won't be able function. My siblings and I have tried to research specific quantitative data surrounding side effects of this treatment, but there are so many variables that it's hard to really get an idea of what he should expect. I thought I would reach out to see if anyone here has experience with whole brain radiation and could speak to personal experiences with the long term effects, like short term memory loss?
