Help for chemotherapy

Hello, my name is Carlos, I am Colombian. In July of this year I applied for the renewal of my visa and I am currently on a bridge visa. On August 17th I had some medical tests and unfortunately they detected a cancerous tumor in my body. I had surgery for this tumor on August 27th and since it was detected in time, the vast majority of this cancer was eliminated. However, the specialist has told me that I have to undergo chemotherapy to eliminate all these cells from my body. Given the situation with my visa and that my health insurance does not cover these processes, tests or medications, I decided to ask for your help to get the money I need to undergo these chemotherapy sessions. I appreciate your help and donation.
