I did smoke for 30yrs and quite 15 yrs ago [/INST] Hi, dairy have gone through your question. I can understand your concern. You are smoking since many years.  So you have high chance of cancer.  COPD per se not increasing the risk, but it is also caused by smoking, so it increased the risk of cancer. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
