I have the habit of smoking but not frequently is there any symptoms for lung cancer.

Question

More heavily a person smokes more risk he has for lung cancer. Also how many years one has smoked also increases the risk, on the other hand many non smokers also get lung cancer, that means there is definite risk of cancer with smoking, but it is not only the factor that may lead to lung cancer, there are other factors also that may cause lung cancer. Coming to symptoms you have asked, first thing to know is that most of the lung cancer patients get symptoms when their cancer has already reached an advanced stage. In other words, most of the patients have no symptoms when the lung cancer has just begin. The symptoms that may suggest the disease suspicion are; cough of some short duration, blood coughed out, chest pain, some times fever and loss of weight. Few patients may feel breathing difficulties. And lung cancer has cure only in early stage and not in advanced stage, so its anyone's guess that how risky it is, if someone gets symptoms of lung cancer, which occur usually at advance stage.
