Talking about clinical trials, I'm wondering: does one, as a patient, have to go hunting & searching for these clinical trials yourself, or do doctors mention these when things start to look dire? Asking for a friend that got osteosarcoma earlier this year (in her lower left leg) that has metastasized. She already had retinoblastoma as a child due to a mutation of the RB1 gene, both are probably related. I don't want to be that friend that thinks they know better than the doctors, but I'm honestly curious.
