The human respiratory system is an vital organ system that carries out life-sustaining processes. Like other organ systems, it is prone to a plethora of diseases, both systematic and non-systematic. The objective of this research article is to compare and contrast two lethal respiratory diseases: lung cancer and tuberculosis. This article discusses the scientific nature, the diagnosis, the treatment, and the social and ethical impacts of the two diseases. In particular, this article dissects and presents ethical issues pertaining to tuberculosis, a disease that has been dubbed a social disease, and lung cancer. This article provides an insight into health sciences and its relationship with the greater society.
Matrix metalloproteinases (MMPs) are enzymes that are highly expressed in tumours and are thought to have an important role in the advancement of cancer. Of particular interest is their contribution to metastasis – the spread of cancer around the body. As a result, they are currently being researched with the endeavour to develop new anticancer agents, with inhibitors of MMPs considered to be a viable option for future use in chemotherapy. Furthermore, these enzymes could be used to improve the way in which the body metabolises anti-cancer drugs, a method in which the drugs are only activated in the presence of MMPs in the tumour, and so reducing the potential for harmful side effects.
