Help Jamario with his immunothera

My name is Tracy-ann, my son was diagnosed two years ago with a rear type of cancer called alveolar robdomysarcoma. He was treated with chemotherapy and radiotherapy and the cancer cells were gone by the end of that year . Unfortunately the cancer returned in January of this year 2016. We were told by the oncologist that they were not sure that they could cure his cancer . So I started to research alternatives and I discovered immunotherapy. I contacted one of the centres in Tampa Florida who has assured me they are able to cure him. This centre is called tampa general hospital . To travel to the U.S we require insurance to cover the cost of the treatment as the treatment would last for three years. We have been unable to get an insurance to cover us . This is the reason for this appeal to raise the funds to pay for the treatment. The cost of the treatment is £2103947, we hope that with your help and support we will be able to raise the money . We greatly appreciate any financial support .
Thanks .
