I am Dr. Vikas Goswami, oncologist, practicing in Noida, Ghaziabad and Delhi. Today I will talk about lung cancer. What are symptoms, when should you suspect, what are the investigation that should be done and how do we treat it. Its symptoms are chronic cough, weight loss, blood in sputum. Sometimes there may be a change in voice or pain in back. We can diagnose it with CT scan. One we find out the problem, the next step is biopsy. We put the camera through the airways or we check from the outside of the body. With this diagnosis, we get to know what kind of cancer are we dealing with. So, there are various types of sub-cancer. The benefit of biopsy that genetic testing can be done. We get to know what mutation needs to be followed and treatment can be planned accordingly.
The next investigation is pet scan. Lungs have stage 4 disease. We do the genetic testing and we try to find out what is its sub-type. We give few tablets to the patient which have amazing results. We give drugs for immunotherapy. For other treatment we have chemotherapy. We also give oral medicines. If the patient's disease is non-metastatic that means it is limited to the lungs. The treatment modality is surgery if it is very early than stage 1 or 2 or we do radiotherapy if it is at an advanced stage. Surgery is the choice for early cancer. So, we believe in teamwork not only about medicines, surgeon, radiotherapist but also of the pathologist and newer modality that is coming. If you have any symptoms, contact your doctor and know about these symptoms.
