Lung cancer is a serious condition which is caused by the uncontrolled multiplication of the cells in the lungs. This can spread to other parts of the body in severe condition. The choice from different treatments available like surgery, chemotherapy, radiation therapy and so on will depend on the extent of spread and the health conditions of the patient.
While using radiation therapy, high energy beam will be focused on the area affected by cancer. This beam has the ability to damage the DNA of the cancer cells. This will disable the cells from multiplying further. The cells will get destroyed and the possibility of them spreading and affecting other parts of the body will get nullified. This treatment can be classified as external beam radiation and internal beam radiation.
In the former, a machine outside the body will deliver the high energy beam to be focused on the tumor. In the later, a thin tube made of plastic will be inserted in to the body which will act as a passage for the transfer of radioactive material to the tumor.
Radiation therapy will be administered to the patient for an average period of six weeks on a daily basis. This treatment is painless and lasts only for a few minutes in every sitting. Different types of radiation treatment are:
• Palliative radiation: This aims at curbing the growth of cancer cells and reducing the pain associated with lung cancer. This is usually administered in the terminal stage of lung cancer when the aim is to reduce the pain than to treat the cancer. Often, this treatment is recommended if the cancer spreads to the spine or brain and causes harm on a much higher scale compared to the side-effects due to radiation therapy.
Radiation is one of the methods that is used to treat prostate cancer. It is also referred to as X-ray therapy and involves using high radiation levels to destroy the cancer cells in the prostate or prevent them from dividing or growing farther. Prostate cancer radiation also aims at reducing any damage to the healthy cells in the prostate. This radiation is carried out in several ways. External radiation is done by directing radiation emitted from a machine on the prostrate. Internal radiation is done by inserting radiation producing materials using thin plastic tubes into the cancerous tumor in the prostate. The materials are temporarily removed from the tumor after reaching the right dose and put back during the next round of treatment.
External prostate cancer radiation treatment is one of the most used methods to treat prostate cancer at the early stages. It is also used in relieving bone pain, which results from the cancer spreading to the bone
External radiation therapy usually takes place at regular sessions, usually five days in a week for a span of eight to nine weeks. During the external prostate cancer radiation, the patient is placed on the table at the right position by the therapist. The therapist only starts the treatment after ensuring the patient is comfortable and relaxed. The patient is closely observed during the treatment session and the room is equipped with an intercom and camera for easier communication. The patient is expected to remain still and inform the therapist of any discomfort during treatment. The therapist will reposition the machine frequently and also help the patient in changing their position. There is no pain experienced during this process as the machine does not touch the patient. A port film is taken during the start of the treatment and every week thereafter to ensure that the treatment is being directed on the right place.
Before starting the radiation therapy, the therapist will make small marks on the patient’s skin to demarcate the treatment area. These marks resemble freckles and are semi-permanent. Patients are advised not to wash off these marks or redraw them if they fade. These marks help in outlining the precise treatment area so that radiation is directed there.
Brain cancer radiation therapy is the process in which a particular form of energy is used to destroy cancerous cells in the body. This treatment is also used to reduce the size of the tumors that are present within the body. This is made possible by the fact that the genetic information on the abnormal cells is eliminated.
Once this occurs, the cells are no longer able to go through their traditional characteristics of dividing and spreading through the body. The ultimate goal associated with this type of brain cancer treatment is to successfully eliminate the largest number of abnormal cells as possible while not damaging the cells that surround the abnormal ones that are considered to be healthy. Here, you will learn more information pertaining to brain cancer radiation therapy.
Individuals that require brain cancer radiation therapy may opt for the external therapy treatment. This type of radiation therapy is made possible by a machine in the external environment of the patient. The technologically advanced machine will emit a large amount of radiation towards the area that the cancer is present.
Those that choose this type of treatment may have it performed on an outpatient basis. While used in other types of cancer such as those that affect the bladder, the prostate and similar areas, this form of treatment has proven to be highly successful for those suffering from the uncomfortable symptoms associated with brain tumors. There are two subtypes of radiation treatment that is considered to be external. They are “Intraoperative Radiation Therapy” and “Prophylactic Cranial Irradiation”.
Internal therapy is another type of brain cancer radiation therapy that many doctors and patients agree is highly beneficial in killing cancerous cells and reducing the sizes of tumors within the body. Instead of using a machine that emits radiation, the radiation is typically contained within a container that is often identified as an implant.
