Husband age 53 diagnosed with Stage iv Lung Cancer on August 15, 2007. He jsut had his third chemo treatment, seven hours once every three weeks. It is unbelievable what he has endured the last two months. I try to be positive but it is so difficult. I want him so much to live but I hate the thought that he is going through so much and then he is going to die. Is there any hope for stage 4 lung cancer...... How long does he really have?
