Cancer is the abnormal growth of cells, and it prevents other cells from obtaining nutrients. If a person is genetically predisposed to the disease, it can be difficult to avoid getting it. However, individuals could still minimize their risk by practicing certain behaviors. For instance, it is essential to adopt a physically active lifestyle, maintain proper nutrition, and avoid smoking. Additionally, it is advisable to always apply sunscreen regardless of whether a person is leaving the house or not. In case one develops cancer despite taking these preventative actions, there are various forms of treatment available. A patient may opt for one or a combination of the treatment options including surgery, chemotherapy, radiation, and immunotherapy (Liebman, 2019). Since people cannot always completely control their environment and lifestyles, understanding the causes, mechanism, and treatment of cancer is the first step towards combating the disease.
