My aunt is 62 and was diagnosed last november with stage IV metastatic melanoma. She had an operation to get a tumor removed and is undergoing an immunotherapy treatment that I believe is experimental. So far it's caused some severe complications (typhlitis) and doesn't seem like it is going to work.
My question is not so much medical but about doctors and medical departments. I'm not sure how to proceed, and un particular if it makes sense to search for opinions in other places besides the oncology department in the hospital in my city (Valencia) in Spain where she is being treated. Basically I don't know how and if doctors share and have access to ongoing clinical studies and new treatments. I don't know if looking for others opinions migh mean stumbling some promising possibility that doctors treating her right now might not be aware of.
