Hi.  My husband fighting Stage 4 prostate cancer metastased into spine area.  Apalutamide and Enzalutamide failed due to adverse side effects.  Chemotherapy pulled after 5 sessions despite good tolerance as cancer continuing to spread.  Now on Radium 223 and tolerating well after 2 sessions.  He also takes tablets for heart, cholesterol, diabetes, thyroid and blood pressure as well as pain killers.  He is still fit and before very overweight has lost nearly 3 stone. He was keen to try and support any healing also bought soursop and apricot seeds however we have now been warned these could have adverse affect.  How can I find out?  I’ve tried research on internet but confused.  Does anyone have experience of this please.  Thank you
