Lung cancer is the uncontrolled growth of abnormal cells. A healthy body is determined by health of each cell by verifying and balancing the cell growth, so they are dividing as the body needs them. When this system is out of control it instigates a superfluous cell growth which cluster together and form a tumour. These clusters of abnormal cells can be benign or malignant. Malignant tumours are considered, cancer". Abnormal cells grow aggressively and metastasize quickly, which is difficult to cure. The most common causes of lung cancer are smoking (nicotine), COPD, family predisposition and atmospheric air pollution. It frequently arises from the epithelial cells, the lining cells of the larger and lower respiratory tract (bronchi and bronchioles), and that is the reason why the lung cancer is called the bronchial cancer. The main function of the lung is gas exchanging between the air we breathe and the blood. Through the lung carbon dioxide is removed from the blood and inhaled oxygen from the air is entering in the bloodstream. Lung cancer is predominantly a disease of the elderly, 70% of people diagnosed with lung cancer are older than 65 years. It is the leading cause of cancer in men and third in women which is a major public health problem. Treatment consists of surgical removal of cancer, chemotherapy, radiation or a combination of these treatments. Health care requires a holistic approach to the patient with lung cancer. A case of a lung cancer patient described in this paper shows that treatment of lung cancer patients requires complex approach and knowledge of professionals with a baccalaureate degree in nursing employed in hospitals, outpatient facilities or those engaged in home care.
