Cancer has become a very common illness world wide for any age but mostly affecting adults. One can get cancer from different places in the body that is why there are so many people with cancer, because of all the different types. Cancer can affect any gender, female or male, and any age. It varies from ovarian cancer to prostate cancer, skin cancer to lukemia. Cancer has been a problem for many years yet we have not found a cure to treat and prevent cancer. If one is affected by cancer there are treatments to help take away this illness affecting their body. This essay is about a specific type of treatment for cancer, radiation therapy. There are different types of forms of particles for radiation, for example, protons and waves like x-rays and visible light. These types of radiations are grouped on how much energy they contain because it can cause different affects. A low type of energy radiation can be radio waves and heat, also known as non-ionizing radiation. Ionizing radiation has enough energy to break chemical bonds and knock electrons out of atoms, some examples of these are x-rays and ultraviolet light rays from the sun. That is why radiation is a way to treat cancer because of the strong energy it has to destroy a cancer cell, actually any cell in the body. That’s the issue with radiation therapy, is it worth the damage? It can damage any cell, wether it is healthy or cancerous, which can cause a major affect in the body later on. Although it sounds scary there are other types of treatments such as chemotherapy, targeted therapy, immunotherapy, photodynamic therapy, etc. So if radiation therapy does not sound like the best there are always other options but they do not develop the same results for radiation therapy.

Radiation is a connection to physics, which was a very important important discovery in science because it has cured many patients who have been affected by cancer when before they were left to die. Radiation therapy, like any other way exposed to radiation, can be a risk. The importance of undergoing this treatment is to see the positive side of it, not just think of the bad things that can come out of the radiation therapy. There is a risk of second cancers but isn’t it worth it? This treatment gives patients the chance to live a longer and normal life, this wasn’t an option before, so it’s important to be thankful for being born in this time period. Radiation might not be seen as a good thing in many occasions but it is now used for the good of the people affected by cancer, it’s a second chance for life.

Surgery allows doctors to effectively remove tumors from a clear plane. Chemotherapy uses drugs to treat the tumor; but often the drugs affect other healthy cells in the process. Using radiation as a treatment can be either precise or vague. Many health stigmas can come from the vague forms of radiation or conventional radiation therapy. Conventional radiation treats both the unhealthy and healthy cells, therefore exposing healthy cells to harmful radiation (Radiation Oncology, 2011, p.6). When healthy cells are exposed to gamma radiation they are also exposed to ionizing radiation. The ionization can cause “breakage of chemical bonds or oxidization (addition of oxygen atoms)” in a cell; the main impact of this is on a cell’s DNA, if two strands of DNA break it can result in “mutations, chromosome aberrations, ...

Main focus of radiotherapy is to cure cancer, to control the growth of the cancer and to relieve symptoms, such as pain. Radiation therapy works by damaging the DNA within cancer cells and destroying the ability of the cancer cells to reproduce [2]. When these damaged cancer cells die, the body naturally eliminates them. The radiation will affect the normal cells will also affected by radiation, however they are able to repair themselves from the radiation in a way that cancer cells cannot [6].
