In my mother's case, IRESSA worked wonder on her. My mother is nsclc, had reoccurance(?) one year after she did the surgery, there were spots all over her both lungs again. The doctor only gave her six months. After she had several round of chemos, she started taking IRESSA. Three months later, the CT scan showed the there were fewer and smaller spots, and another three months later, all the spots were gone! She has been taking it for one and half year now, tumor free and felt great. The only side effect is minor diahrea.
