Introduction
An average of 7.9 million people dies annually across the globe because of cancer. This translates to about 13% of the overall mortality rate in the world. Cancer is a class of diseases exhibited by growth of uncontrolled cell growth in the body. There are over one hundred (100) different types of cancers. However, each type is classified according to the tissue or fluid where it originates. One particular type of cancer identified through that manner is the lung cancer. Lung cancer has the highest mortality rate than any other type of cancer as studies record. This paper critically explores the approach to care of cancer, thus different sections are included in the discussion in order to shed light on the subject accordingly.
Pathophysiology of Cancer
Different statistics justify that the lung cancer is the most common type of cancer in the US. Therefore, this paper will mostly refer to this type of cancer. Cancer originates from a certain tissue in the body and the spreads from that point. For example, lungs cancer originates from the lungs then spread to other surrounding organs in the body. Lung cancer is believed to originate from the bronchi lining (main lung’s airways), although it can also start from other areas including the alveoli, trachea or bronchioles which are in the respiratory system (Nader, 2014). Lung cancer occurs when the cells based in the lungs grow at an out-of-control rate. Medical Researchers believes that this type of cancer develops over an extended period, usually several years.
Almost all cancers particularly lung cancer, which is the focus for this study are carcinomas, an implication that they begin from the organs lining tissues or the cover part of an organ. The cancerous tumour cells grow and spread differently according to each type of cancer. If the tumour stays in one place and demonstrates little growth, it is said to be benign (Nader, 2014). However, if the cancerous cell moves throughout the body using the blood system or lymph systems, it destroys other body’s healthy tissue. This takes place through a process called invasion and such tumours are more dangerous and referred as malignant tumours.
Notably through studies, it is true tumour cells grow and spread differently depending on the type of cancer. In that sense, this calls for different methods of cancer treatment for the different types. The different methods taken for the treatment ensure that each type of cancer is handled in the right way, and using the appropriate treatment measures. With reference to the American Cancer Society (2014), it is recorded that about 85 % to 90 % of all lung cancers belong non-small cell lung cancer. Non-small cell lung cancer form in the tissue found in the lung, mostly in the cells that lining the air passages. It is worth noting that they damage tissue surrounding it and then interferes with normal lung functioning. This ty...
