alternative natural supplements instead of chemo

Hi all,

I am a 24 year old diagnosed with stage 4 bone cancer (paro osteosarcoma). 

i am soon to undergo chemotherapy this week to treat my bone cancer which is stage 4 and has spread to the lungs. I have been told that bone cancer is chemo resistant so there is a very low chance of the chemo working, around 20%. 
 

In an ideal world i really do not want to go ahead with the chemo for several diff reasons (coronavirus and the long term side effects). I am currently taking some herbal supplements, along with a immune system booster called Biobran which has numerous testimonies in helping reduce cancer tumours without needing chemo. 

I was wondering if anyone here has refused chemo and tried alternative natural medicines to treat their cancer? if so, has it worked for you? 

I am due to start chemo this week and am really doubting if i should go ahead with it. Part of me wants to continue with my current medication and get a scan done in 4 weeks to see if they are working. Any help/advice would be great xx
