Hi, Nothing is rare. I'm now 85, I was exposed to asbestos from 1955 to 1974, while aboard US Navy ships, I also smoked some of that period. After retiring in 1974 I stopped smoking. In 2000 I had my 1st chest X-ray ever followed by a CT scan; plural thickening, scarring, calcification, and many nodules, had a needle biopsy of the largest one, negative for cancer. My pulmonologist sent me for CT scans so often I refused for several years. They now use a low-dosage scan so I continued scans at least every 6 months, in 2018 a nodule in my upper left lobe became cancerous resulting in a lobectomy . Mesothelioma., cancer of the plural I believe is caused by asbestos only. My cancer was determined to be caused by asbestos more likely than by smoking.
