III. Explanation on how the various body systems are affected by the disease/condition

When a person suffers from lung cancer, he/she has some abnormal cells that tend to cluster together to create a tumor. Cancer cells have a tendency to grow without order or control, destroying the healthy lung tissue located around them. These types of tumors can be defined as malignant tumors. The various body systems are affected by lung cancer when a tumor is metastasizing to other organs. For example, a tumor may press on the esophagus. In this case, a person with lung cancer has problems with swallowing. Besides, lung cancer may cause shoulder pain, numbness in arms. These signs indicate on the availability of a tumor in the upper part of the lungs. In fact, cancer originated in lungs may be spread to any organ of human body. However, the most common organs are “the brain, liver and bones” (Walker, 2006, p. 29). For example, a person with brain metastases experiences severe headaches and even vomiting. The location of tumor affects the ability to move, vision, balance, speaking, as well as the ability to focus (Walker, 2006).

IV. Some medications/treatments that are available

Lung cancer is often hard to treat. There are different medications/treatments for different types of lung cancer are available. As a rule, physicians should decide on treatment for a particular type of lung cancer. In this case, he/she will take into consideration not only the type of cancer this or that patient has, but also the patient’s age and general state of health, the stage the lung cancer, and its spread to other organs of the body.

There are several types of treatments: surgery (when one of the lungs is removed), chemotherapy (pills, intravenous drip and injections), radiation therapy procedures (killing cancer cells by high-energy radiation), targeted therapies (Gefitinib (Iressa) and erlotinib (Tarceva)) and photodynamic therapy (Scott, 2012).
