I am a 40 year old non smoker. A chest xray revealed a small nodule at the base of my left lung and today after a CT scan the doctor says it is calcified and not to worry; however, they did find another small nodule on the right side that is not calcified. She said to wait 12 months to repeat the scan and I felt worried in waiting that long so we decided to do the repeat in 9 months. My father, a very heavy smoker died at 42 of lung cancer . Do you think that this along with being exposed to second hand smoke my whole life warrants doing another scan sooner than 9 months? Trying to not worry about it will be difficult.
