I am a 45 year old smoker (27 years) and during a chest X-Ray, a 10mm nodule on my upper lung was found. I had a follow-up CT scan and they found that the nodule was 30mm. My family doctor is recommending I wait a year and have a follow-up CT scan. Question: Should I get a second opinion? I feel like my risk factors are high and that fact that the size was 10mm on the X-Ray and 30mm on the CT scan that further investigation is probably warranted. I'm disappointed with myself for not quitting long ago but time just seems to slip away you know? Now I have scariness and I don't like it…….
