Radiation Therapy

Why Choose Florida Hospital?

A treatment used to kill or shrink cancerous cells, radiation therapy can be administered in different ways. The therapy uses x-rays, gamma rays and charged particles to attack cancer cells and tumors through external or internal application. This therapy works best at the early stage of cancer, since it is designed to kill targeted cells in one area of the body. Florida Hospital Cancer Institute offers patients the most advanced cancer treatment and radiation therapy available. Here, doctors draw on years of experience, specialized training and access to cutting-edge technology to provide effective diagnostic tests and treatments.

Radiation therapy is a treatment for cancer that uses x-rays, gamma rays and charged particles to target cancerous cells. These rays kill and shrink cancer cells while avoiding surrounding normal cells. Depending on the goals of treatment, radiation therapy can cure the cancer, relieve symptoms or control the disease.
 
There are two types of radiation therapy, both available at Florida Hospital. Depending on the type of cancer, the location and the patient’s health, different administration methods may be recommended to improve effectiveness of treatment.
 
These are the types of radiation therapy:
  • External radiation therapy: This cancer treatment uses high doses of radiation to kill cancer cells and shrink tumors. Similar in process to receiving an x-ray, the patient lies still while a machine directs radiation to the cancer site. Most patients receive treatment once a day for five consecutive days, and repeat this process for two to 10 weeks. 
  • Internal radiation therapy (or brachytherapy): This type of radiation is implanted into the body, and allows the radiation oncologist to direct the radiation to a smaller area in a shorter time span than with external radiation. The radiation material is sealed inside small implants and inserted into the body using a catheter. The three main types of implants are low-dose rate implants, high-dose rate implants and permanent implants. The lose-dose rate implants stay in the body for up to a week before being removed. The high-dose rate implants stay in place for a few minutes before removal. In both cases, after the implants are removed, the patient is no longer radioactive and can be around other people. Permanent implants, meanwhile, give off small doses of radiation for a few weeks or months and then taper off and stop. These patients should avoid close contact with children and pregnant women. In some other cases, especially for cancers of the thyroid and some types of lymphoma, the radiation can be orally ingested, and travels throughout the body seeking and killing cancer cells. 
 
Radiation therapy can be combined with a variety of other procedures for a complete and effective treatment plan.
