Radiation Therapy is a special kind of energy carried by waves or a stream of particles which has the ability to affect the structure of the cells. It is one of the main methods to treat cancer, along with surgery and chemotherapy, and to also treat some non-cancerous conditions.
Localized fields of energy are used to stop the growth of cancerous cells. These fields are generated by a highly specialized machine called a linear accelerator. These energy fields are directed at the tumor site after intense planning and preparation so that the treatment will be very individualized to your condition.
The goal of treatment can be to cure, control or relieve symptoms. Each patient is monitored very closely to determine if the treatment is producing the desired effects.
Before you begin radiation treatments you will undergo testing to determine exactly where the tumor site is located. You will then go through a "simulation" process to plan exactly where your treatment will be focused. Your skin may be marked to aid the treatment team to make sure your treatments are given to a consistent location. These marks will not be permanent on your skin. Our nurses will spend time with you before your treatments begin to ensure that you understand what to expect from your therapy and that all your questions are answered.
After your treatments begin, you will be followed closely by the treatment team by informing them of any problems or concerns that you are having so that these can be addressed promptly before they have a chance to develop into a larger problem. Generally, patients do not have any restrictions from the radiation treatments and are encouraged to remain as active as possible. After your treatments are completed, you will be followed by your treatment physician and monitored as needed.
Q: Are the treatments painful?
For the most part, the treatments themselves are not painful and it is similar to having an X-ray. However, in 2-3 weeks your skin may become sensitive and irritated. Also, depending on what part of your body is being treated, other concerns may appear, such as discomfort in swallowing.
Q: Is the patient radioactive while on treatment, and can the patient be with family and children?
Any patient treated with external beam radiation is not radioactive and there are no special restrictions.
Q: Will the patient lose his/her hair?
Hair loss is only likely if the head and hair follicles are in the treatment field.
Q: What risks are associated with radiation therapy?
Skin reactions, fatigue, low blood counts and possible, but unlikely, nausea and vomiting. All of these potential risks will be managed by your physician and healthcare team.
Sometimes acute side effects may happen which generally resolve within 2-4 weeks after your treatment is completed. These side effects depend upon the area of your treatment. Your physician will explain all these potential concerns with you before you begin treatment.
