I lost my brother this past April to lung cancer. He never smoked a day in his life. But when he was diagnosed he was already in stage IV and it had spread everywhere. Sad thing is there really weren't any over obvious signs. He was asthmatic and always had a cough. It wasn't until he passed out from coughing so hard did he go to the hospital and that's when it all started. Diagnosed in February and taken from us in April. Miss him every day! I hope they find a cure soon for this horrible disease.
