I'm sorry you had that horrible experience. I'm a patient myself. I don't know how to answer your question, but my heart goes out to you. My little brother died when he was 5 of cancer due mostly of Dr incompetence. It's hard, but the pain does soften over time. I hope you get the answers your seeking.
I am so surprised about this! You could call who is in charge at the clinic he was treated for or oncology. Talk to the oncologist in charge. I am truly sorry for you loss. I hope that you can find the answers to your questions.
Thanks! Your answer is awaiting moderation.
