Immunotherapy treatment

I’ve been diagnosed with Stage 4 stomach metastatic cancer since January 2017. I’ve been on 4 treatments already and have had some progress until the chemo has stopped responding recently. My recent CT scan showed that my cancer has grown again and one of the lymph nodes has grown in size. Immunotherapy is probably my last hope for a cure however this isn’t funded by the government. This will initially cost me $12,000 AUD for 3 treatments $4000 per dose. This is money I don’t have and now am asking for your help in order to have a chance of staying alive. If you can contribute I will greatly appreciate it. I’m yet to see my dream as a music artist come true yet and I’m so close to seeing this a reality. It is one reason why I want to stay alive.
