Lung cancer can be broadly classified into two categories such as non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Non-small cell lung cancer can be further classified into adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Squamous non-small cancer develops from the cells lining the airways and is found near the center of the lungs in one of the main airways. Non-small cell lung cancer globally accounts for 85% to 90% of lung cancer, in which adenocarcinoma and squamous cell cancers are responsible for approximately 40% and 30%, respectively. Prominent symptoms of squamous non-small cell lung cancer include excessive coughing, wheezing and shortness of breath, chest pain, and occurrence of blood in sputum. Many physicians misunderstood this disease with collapsed lungs or pneumonia. The disease usually takes longer time to develop from confined tumors to invasive cancer. Primary diagnostic technique comprises sputum test, bronchoscopy, MRI scan, needle biopsy, and CT scan among others. In Australia, squamous non-small cell lung cancer is a common type of lung cancer accounting for 29% of total cases of lung cancer.
