My husband's sister died of lung cancer that metastisized to the brain, bones, etc in Dec. 07. She had been sick for about 15 months and was 47 years old at death. My husband, who is 41 years old, just had a spot show up on his right lower lung (less than centimeter). This showed up during an x-ray, then a cat scan with contrast. Dr. recommended waiting 3 months doing another scan to see if it changed. We don't feel comfortable waiting that long, especially after caring for his sisterl. He is not, and never has been, a smoker. The doctor said it is too small to biopsy, what options are available? We are very worried.
