I have a brother who was diagnosed with a tumor in his brain a few weeks ago. I want to tell my parents, but I promised him not to tell my parents. He wanted to do it himself. However, he said he won't tell my parents any time soon. If you were in my shoes, what will you do? I will be in medical school, but not yet. So I don't really know much about how serious the situation is. I know early treatment is always the best course of action, but a promise is a promise. Please help, thanks.
