I'm 13 and the career I want is being a Cancer Treatment Doctor, but I want to know which kind of cancer to be treated on someone makes it mandatory for me to see their blood because I'm really squeamish (I have a phobia of seeing lots of blood), and if that cancer to be treated makes it mandatory for me seeing a lot of blood, then I'd like to know which is a cancer to be treated that does not make it mandatory to see a lot of blood (just some in one of those glass plates doctors and scientists put under a microscope). Thanks!
