Rectal Cancer, not Colon, that spread to lungs

Hi, my husband was diagnosed with Rectal Cancer it'll be 3 yrs ago this March. Shortly after the diagnosis, treatments, surgery on rectum, he was diagnosed with lung cancer. His onc said it was from the rectal cancer. A few days ago we went for ct scan and the tumors had grown considerably since last scan. Biggest tumor is 2 inches.  Onc.. said there was to many tumors to count in both lungs... Hehas decided(my hsband)  not to do any treatments this time. Chemo just about got him the first time. My question is, has anyone used any homeopathic treatments that have actually worked?
