Sorry to read about your loss and experiences. FWIW, doctors knew in 400 BC to not cut into tumors because it led to death. Tumors are best left alone, and the body built back up to dissolve them naturally.
Hospitals and doctors are an outrage, especially since there are so many known cures for cancers out there. They are nothing less than torture chambers disguised as nice places. May God bless your kind heart.
