Thanks for responding, Dee. The doctors did not explain anything except by saying repeatedly that "we are sorry, that is the way the cancerous cells develop. Do you need more pain killer?" I try to find out more about wound caring, and find the description about ulcerating malignant skin lesion with nodular growth matching what's happening with mom. There is no sign of healing, the nodules keep growing, now behind her ears and extend to lips, and then burst with yellowish powdery substance and then a new cavity is formed. Mom is also complaining about sore throat recently, and her left eye keeps swelling. In Frank's case, did his face heal? I just want to know what to expect next.
