Cancer Cancer is a broad category of the disease characterized by undefined outgrowth of cells that divide uncontrollably to form nasty tumors within an individual. The cancerous cells causing the tumors grow and divide creating new blood vessels to feed themselves in a process called angiogenesis (Veeratterapillay, 2012). The tumors often spread to other parts of the body swiftly due to the unregulated growth and dividing of the cells through the bloodstream or the lymphatic systems in the body (National Cancer Institute, 2014). These tumors grow relatively, destroy the health tissues in the body, and create interferences creating interferences that alter with normal body functions such as such as the digestive and the nervous system. The most vulnerable parts in the body that can easily beget the tumors include the breasts, lungs, cervices, colon, and rectum.
Today’s scientific research and advancement in both knowledge, understanding, and battling of cancer, patients now have a better chance at successful treatment of their diagnosis, and living a longer, happier life in the face of cancer.
What treatments are the most effective to curing cancer? Cancer has become a very common illness which has affected more that 12 million people over the world since the 1970’s (Ahmedin, 2011). The diagnosis of cancers has been on the increase and many new kinds are being discovered. There are over 200 different kinds of cancers, most of which many people are unfamiliar with. Each type of cancer has different symptoms and many are diagnosed differently.
Introduction The body is composed of cells. Normally, these cells divide at a composed and calculated manner. If cells die or are destroyed, the body creates more cells through the division of existing cells. However, occasionally, problems with some cells in the body may occur.
These cells (that have cancer in them) are able to go into other muscles or part of body by growing into them. They can also get into other tissue by putting themselves into faraway places in the body by “Metastasis”. Metastasis is a process that when cancer cells move through the blood stream or lymphatic system. When this happens, a person’s cancer can be spread inside his/her body.
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.

A new innovative cancer treatment called Radioimmunotherapy or RIT joins conventional radiation therapy with immunotherapy. RIT uses monoclonal antibodies to target specific cancer cells and minimize damage to surrounding cells and tissue. Monoclonal antibodies (MAbs) are laboratory made immune proteins engineered to attach to antigens of specific cells. These antibodies mimic antibodies naturally produced as part of the immune system. Originally MAbs were made completely from mice cells and when these were introduced into the human body, the immune system would react against them. This decreased the success rate of the treatment and many times the immune system would destroy the MAbs even before treatment could be provided. As studies progressed, researchers were able to replace mouse MAbs with a mixture of human and mouse cells called chimeric antibodies. Continued studies have now led to humanized antibodies. Humanized antibodies consist of fragments of human antibodies instead of whole ones. Researchers also found that by using smaller fragments that there was a greater chance for the antibodies to reach the targeted cells. Once the engineered MAbs have been made, radioisotopes are attached through a process called labeling.
Cancer Chemotherapy and Personalized Medicine Cancer is a leading cause of mortality worldwide. It is known to promote the harboring of accumulated genetic alterations in normal host cells, which then promote cancerous growth. Cancer chemotherapy attempts to eradicate or functionally disable tumor cells by the use of synthetic and/or natural compounds while preserving normal cells. Chemotherapeutic agents can eliminate tumor cells by direct cytotoxicity, activating host immune response, inhibiting the proliferation processes of tumor cells and inducing apoptosis.
Surgery is an option to remove all the cancerous masses or tumors. Radiation therapy is also an option where radioactive substances kill cancer cells and can shrink tumors. Chemotherapy uses chemicals to destroy cancer cells. Immunotherapy causes a humans immune system to wake up and recognize the cancer and destroy it. All of these treatments save many lives by killing the cancer cells or slowing their growth.
Cancer Immunotherapy can be described as a form of treatment that uses different parts of ones immune system to fight against cancer. There are many forms of cancer immunotherapy, with some of the most common forms being different forms of Monoclonal Antibodies (mAbs). Naked mAbs, Conjugated mAbs, and Bispecific mAbs. While immunotherapy can sometimes cause serious issues, doctors have seen deadly tumors disappear because of the genetically modified
