Last October my husband of 49 years was diagnosed with stage 3b lung cancer. He did six rounds of two chemo drugs simultaneously with radiation (35 treatments). He handled both very well. Finished treatment end of January and is now on an immunotherapy drug for a year. He is stable, no progression or spread outside of lung but no shrinkage either. It is a devastating disease. You live from scan to scan. I feel for Rush and his wife. There are a couple of 10 year+ LC survivors in our LC support group. One woman has a specific mutation for which there are targeted drugs. She had been kept alive by clinical trials for the past 13 years. Stage IV.
Prayers for your husband and you. Glad he has handled treatment well. It is always encouraging to hear that there are survivors of this disease. Praying for new treatments on the horizon.
