Gene therapy for 9/11 Responder

I am a 9/11 first responder recently diagnosed with cancer I worked radiation treatment of transporting patients from Bellevue to NYU for three years and out of the hundreds of patients I encountered the treatment only worked for one person... I don’t believe in chemo and radiation but I do believe that gene therapy is a viable treatment for cancer.. I am asking for help for this treatment for me and my family my wife and my kids... I don’t have enough for this treatment and I am getting no where with the resources that are out there.... I need your help so I can be here for many years to help my family... I am a proud person and would not ask if I didn’t need the help I am at my wits end... the treatment is 300k plus but I need 15k as a down payment thank you for reading my story and god bless you all...
