Radiation Therapy Advantages And Disadvantages

• Radiation therapy. Radiation therapy is the use of high-energy X-rays to kill cancer cells.

Radiation therapy is the use special machines to convey high-energy rays that damage cancer cells and stop them from growing. The radiation can be directed to a specific area of the body or the whole body. Some side effects that come from the therapy are fatigue, hair loss, nausea, or red, dry, itchy skin.

Radiation therapy is the ionization of atoms in tissues resulting in formation of highly reactive radicals in a well-defined, restricted volume (1). In other words, ionizing radiations are used to eradicate tumors and at the same time preserve structure and function of normal tissue. A limitation is prevented from being a problem. If bone marrow or neuronal cells are destroyed or injured, they do not regenerate. However, with radiation therapy, these cells are often saved from injury or destruction, unless the tumor is infecting bone marrow or neuronal cells. Today, radiation therapy is the most popular type of cancer therapy in use. It is used to treat one-half to two-thirds of all cancers, which translates to more than ten percent of the population

When treating cancer one of the treatments is surgical removal of tumors. Many surgical procedures carry risks of complication such as bleeding, tissue and organ damage, infections or even death. Radiation therapy involves the uses of radiation such as gamma rays or electron beams to kill cancer cells. Radiation therapy can increase the risk of developing addition cancers. Radiation therapy and chemotherapy can have patients experience pain, hair loss, nausea or even vomiting. Medical innovations beginning in the late 1950s have allowed patients to receive stem cells transplants to replace bone marrow damaged by cancer or cancer treatments.

Radiation therapy can be used anywhere in the body to treat any kind of cancer. Depending on what type of radiation therapy, it can have some side effects. The most common ones include fatigue, hair loss near the treated area, and skin darkening in the area exposed to a beam of radiation. ("Radiation Therapy for Cancer,” 1) There are also safety concerns that patients have when they are treated with radiation therapy. Many people that receive radiation therapy treatment, worry about exposing family and love ones to radiation, as well as the side effects. Radiation effects on the normal tissues are divided into acute and chronic effects (Schreiber). Acute effects occur during the course of therapy and during the post therapy period (approximately 2-3 weeks after the completion of a course of irradiation) (Schreiber).

It is the use of high-powered x-rays that destroy tumor cells. A radiation oncologist is the doctor who specializes in radiation therapy. There are two types of radiation therapy: 1.) external-beam radiation which is given from a machine outside the body and 2.) internal radiation which is given using implants. The external-beam radiation therapy is much more common than internal radiation. It can be directed at the tumor in many ways such as conventional radiation therapy, 3 dimensional conformal radiation therapy, intensity modulated radiation therapy, proton therapy, stereotactic radiosurgery, and fractionated stereotactic radiosurgery. Choosing one of these techniques depends on the size and location of the

Radiotherapy, also called radiation therapy, is the treatment of cancer and other diseases with radiation. Radiotherapy is used when the entire primary tumor cannot be surgically removed. Radiotherapy deposits energy

Radiation Therapy is often used to treat the the cancer (CML) if it has moved/spread outside of the bone marrow and into other parts of the body.

Therapeutic nuclear medicine is used in many different ways to help and treat patients when they are fighting cancer or other diseases. Doctors will take the steps to do whatever they can to make sure that the patient will survive or at least achieve improvement in their health to some degree. When a patient is undergoing surgery to remove the cancer cells, the doctors will often have them go through radiation beforehand to shrink the cancer or tumor down to a size that is easier to remove and to ensure they are not removing more than necessary. Often during surgery, the surgeons will again treat the patient with radiation while they are open so that the radiation is hitting the direct tumor or cancer cells being targeted. Another benefit is that it provides the radiation treatment without having to direct it through the skin again. This reduces the amount of radiation that the patient is getting to a certain degree. Once the surgery is over, the patient will often have to continue with more treatments to make sure that, if anything was missed, it will be attacked by the radiation and be prevented from spreading. Eliminating the cancerous cells can often take more than one type of medical therapy, and it can often take multiple treatments (Radiation

Each treatment session will take about 10-30 minutes and you won’t usually need to stay in hospital.

tumors are treated but if surgery is not a viable treatment radiation can also be used.

The process of radiation therapy uses small amounts of very high-energy radiation to destroy the cancerous cells, making them unable to reproduce. "About 60% of all patients with cancer receive radiation therapy for curative intent, tumor control, or palliation of

Radiation works by damaging the genes in cancer cells. DNA genes control how cancer cells grow and divide. When radiation damages the genes of the cells, they can not grow and divide any more. Over time, the cancer cells die. This means radiation therapy can be used to kill the cancer cells and shrink

Radiotherapy can be used with or without other treatment modalities like chemotherapy or surgery .

In 2007, it is predicted that almost 1.5 million people will be diagnosed with cancer in the United States (Pickle et al., 2007). More than half of these cancer patients will undergo the use of radiation as a means for treating cancer at some point during the course of their disease (Perez and Brady, 1998). Cancer, a disease caused by an uncontrollable growth of abnormal cells, affects millions of people around the world. Radiotherapy is one of the well known various methods used to treat cancer, where high powered rays are aimed directly at the tumor from the outside of the body as external radiation or an instrument is surgically placed inside the body producing a result of internal radiation. Radiation is delivered to the cancerous regions of the body to damage and destroy the cells in that area, terminating the rapid growth and division of the cells. Radiation therapy has been used by medicine as a treatment for cancer from the beginning of the twentieth century, with its earliest beginnings coming from the discovery of x-rays in 1895 by Wilhelm Röntgen. With the advancements in physics and computer programming, radiation had greatly evolved towards the end of the twentieth century and made the radiation treatment more effective. Radiation therapy is a curative treatment approach for cancer because it is successful in killing cancerous tumor cells and stop them from regenerating.
