please help my son Dylan Tomlinson

Good afternoon. I want to take the time to introduce my son Dylan. He is an amazing young man. He's 16 years old getting ready to turn 17 next month. He is a very intelligent young man. He is a leader and follows his heart. When he makes his mind up that is it. He will help anyone he can and will go out of his way for you. He is an exceptional artist and loves anime. He's all about style and takes care of his appearance even when he's not feeling well. He gets good grades and teachers love him... About 2 years ago he started having nose bleeds a couple days a week. Then he sounded congested so we took him to his primary doctor and they said it was allergies. Put him on Claritin and nasal spray. He was constantly calling me at work telling me he doesn't feel good and has a severe headache. I thought he just didn't want to be at school. After multiple times seeing the doctor and getting told the same thing something just didn't seem right. Why is my son congested for so long? Well, his nose bleeds started happening about 3 times a day. He would be watching TV or cooking and it would just pour handful of blood. Scary it is. Until one night he sneezed and blood went everywhere. We couldn't stop the bleeding rushed to the ER. After having a nasal rocket put up his nasal cavity and being extremely uncomfortable. We saw an ENT doctor. They did a CT scan and come to find out my son has a tumor in his pharynx(nasopharyngeal tumor). The Dr did a surgical biopsy and said this type of tumor is very rare. His breathing is restricted by this tumor. His whole right nasal is blocked and his left nasal is 3/4 blocked. It sit directly on his soft palate and has grown into his cranial but has not reached his brain yet. THE INSURANCE WON'T COVER THE COMPLETE PROCEDURE..So we are asking for all the help we can get. Any donation is greatly appreciated. We would be very grateful. Thank you all for taking the time to read this and we love you all. May God bless you and your families. Thank you
