Radiation therapy is an important practice in a lot of hospital and clinics many people are not aware of. It is also known as Radiation Oncology, and it is for the treatment of cancer by using beams of high-energy waves called radiation as the UI Cancer Information Services defined it. Radiation therapy plays important role in helping cure cancer. Radiation therapy is given to cancer patients in order to kill the cancer cells or it may slower the growth of cancer cells (UI Cancer Information Services, 2011). Therapy can be used to reduce pain or pressure by shrinking tumor, in cases where cure is not possible.
Radiation is also used for the treatment of diseases within different anatomic structures, such as cancer. What is medical imaging? Medical imaging is techniques that are used to view anatomical structures and monitor diseases. Medical imaging can be used to diagnose, treat and potentially cure patients without harming them in anyway. Medical physicists are... ... middle of paper ... ...ple would have permanent disabilities, because of the internal damages that has occurred to them and cannot be detected, but through the use of radiation specialists can diagnose the damage that has occurred internally so as to give a chance for professionals such as doctors to give specific treatment for the damage.
Radiation is most commonly used to treat localized cancers as opposed to cancer that has spread throughout the body. The goal of radiation therapy is to kill cancer cells or at least limit their ability to grow and divide by damaging their genetic material. Like chemotherapy, radiation therapy is not perfectly precise in its targeting of cancer cells, and some normal, healthy cells can also become damaged. There is also surgery which the surgeons who specialize in tumor
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.
CANCER DRUG RESISTANCE Introduction: • Treatment of cancer varies person to person depending on the variety in individual factors because every cancer has specific pathological and molecular characteristics such as location, health and extent of disease. • The main part is to destroy the cancerous cells by least harming the normal tissue. Tumors can be present in the parts of the body where drug cannot easily penetrate or could be protected by the local environments due to increase tissue hydrostatic pressure or altered tumor vasculature. Chemotherapy: • There are several treatments to combat cancers which can work well alone or in combination with sequentially or simultaneously. Of those treatments the most important one is the use of drugs and is called chemotherapy.
These treatments are radiation therapy (which uses radiation to kill cancer cells); chemotherapy (which uses strong medications to kill cancer cells); and biological therapy. In some cases, at least a part of tumour can be taken out through surgery. But this is not the end of treatment. After surgery, sick people may need radiotherapy or chemotherapy to keep the tumour from growing again. One big problem of treating cancer is that most things that kill cancer cells are also kills normal and healthy cells.
In addition, cancerous cell also creates their own blood vessels for oxygen and nutrients which is essential for the growth of the cell and is also known as angiogenesis. There are various ways of treating this, one is through localised treatment; surgery where you work on the cancerous areas of the organ. Another localised treatment is radiotherapy which beams gamma rays or x-rays used for the cancer treatment (1). Chemotherapy is also a conventional treatment of cancer; this is a systemic type of treatment this means that it goes all around the body, and has certain drugs which stop the process of cancer cells from developing. For example the cyclophosphamide drug binds the DNA during replication of the DNA.
Everyday doctors all around the world are using their skill of reading cells through microscopes to figure out a way to treat and cure cancer. Chemotherapy and radiation seem like the main source of treatment but some people choose to take a more natural route that is not so hard on their body. But which one is best? It is said that most people decide on chemotherapy or radiation to help shrink their cancer because these two options can eliminate cancer. Radiation starts out by the cancer patient receiving an x-ray of the area of the body where the cancer is located for they can verify the area that the radiation needs to be admitted to.
Those who are pregnant, have systemic lupus, or scleroderma are not candidates for radiation, due to the hazardous health situation and the failure to recover correctly. While radiation is unsafe for an unborn baby, it is... ... middle of paper ... ...tion therapist throughout the course of treatment, but not necessarily every visit shall they see the radiation therapist. Radiologist oversee both the technicians and the therapist, the patient will interact with the radiologist when reviewing the progress the patient has made in their radiation treatments. At this time the radiologist may change the treatment path to better suit the cancer patient. The patient will have the same radiologist throughout the treatments.
Some feel that the radiation treatment of invasive breast cancer is too complex and harmful, so they will avoid it and go through chemotherapy. Others believe that combining radiation therapy with chemotherapy is necessary as their doctor’s instruct.
