Risk of lung cancer and it's prevention!

Lung cancer is the one the leading causes of death among all malignancies. It is acknowledged that smoking is an important factor to develope this cancer. Usually, bronchogenic type lung cancer is common among smoking induced lung cancer, which can be diagnosed with conventional radiological examination (normal chest X-ray). However, it is suggested that lung cancer, located in the peripheral region is difficult to diagnose by normal chest x-ray. The another problematic issue is, sometime, this peripheral lung cancer is symptomless among patients. This type of lung cancer is diagnosed in the fatal stage. For early diagnosis, radiological examination, computed tomography (CT) is useful for the better treatment and prognosis.
