Delay in the diagnosis of any kind of cancer can lead to several complications in the advanced stage. It is no different in the case of lung cancer, which is a leading cause of Cancer deaths in the Western world.
Even though cancers such as breast cancer, cervical cancer, prostate cancer etc., have improved mortality rates, in the current times, the survival rate of lung cancer remains the same as before, that is between 10 and 15%. This is due to the fact that the cancer is already advanced and has already disseminated in the body by the time patients presents it to doctors.
Nearly 80% of patients have an advanced stage cancer when they get it diagnosed, excluding them from curative resections.
