Lung Cancer Surgery Market Dynamics, Segments and Supply Demand 2015-2025

Uncontrolled growth of abnormal cancerous cells in either of the lungs confirms presence of lung cancer. These abnormal cells undergo rapid division and form tumors andeventually begin affecting the lung’s ability to provide oxygen to the bloodstream. Cancer that originates in the lungs is known as primary lung cancer whereas secondary lung cancer initiates in other parts of the body, metastasizes and reaches the lungs. The mode of treatment of these two types of cancer differs from one another. Lung cancer is number one leading cause of deaths in the U.S. and worldwide. According to National Cancer Institute, in the year 2012, the number of deaths due to lung cancer accounted to around 160,340 cases and there were around 220,160 new lung cancer diagnosis cases. Also, as per World Health Organization (WHO), cancer accounts for around 13% of the global deaths and lung cancer alone results in around 1,370,000 deaths annually.

Non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) are the two major types of lung cancer classified on the basis of microscopic observation. NSLC accounts for around 80% of the lung cancers whereas SLC accounts for the remaining 20% of the lung cancer cases worldwide. NSLC is further categorized into four types namely, adenocarcinoma, bronchioalveolar, squamous cell carcinoma and large-cell undifferentiated carcinoma. The two major causes of lung cancer are inhalation of carcinogenic substances and genetic predisposition inherited from family members. Tobacco, arsenic, radiations such as X-rays and UV rays and asbestos are some of the examples of carcinogens. Around 87% of lung cancers are associated with inhalation of carcinogens and smoking. On the other hand genetic predisposition either directly causes cancer or increases the chances of developing lung cancer due to exposure to certain environmental factors.
