The radiation given off by this source damages the DNA of nearby cancer cells. Brachytherapy
Brachytherapy is a form of radiotherapy where a sealed radiation source is placed inside or next to the area requiring treatment. Brachytherapy is commonly used as an effective treatment for cervical, prostate, breast, esophageal and skin cancer and can also be used to treat tumours in …
Brachytherapy to Treat Cancer. Brachytherapy is a type of internal radiation therapy that is often used to treat cancers of the head and neck, breast, cervix, prostate, and eye.
It is safe for people to be near you-even young children and pregnant women. For a week or two, you may need to limit activities that take a lot of effort. Ask your doctor what kinds of activities are safe for you and which ones you should avoid. With brachytherapy, the radiation source in your body will give off radiation for a while.
For many patients who undergo breast conservation, partial breast brachytherapy may be the optimal choice, allowing for excellent clinical outcomes, potentially reduced toxicities, and improved cosmesis.
The differences relate to the position of the radiation source; external is outside the body, brachytherapy uses sealed radioactive sources placed precisely in the area under treatment, and systemic radioisotopes are given by infusion or oral ingestion. Brachytherapy can use temporary or permanent placement of radioactive sources.

Your doctor will place the catheter or applicator into your body before you begin treatment. Techniques for placing brachytherapy include: Interstitial brachytherapy, in which the radiation source is placed within the tumor. This technique is used for prostate cancer, for instance. Intracavity brachytherapy, in which the radiation source is placed ...
For example, radiation can be placed in the vagina to treat cervical or endometrial cancer. Episcleral brachytherapy, in which the radiation source is attached to the eye. This technique is used to treat melanoma of the eye. Once the catheter or applicator is in place, the radiation source is placed inside it.
Most brachytherapy is put in place through a catheter, which is a small, stretchy tube. Sometimes, brachytherapy is put in place through a larger device called an applicator. The way the brachytherapy is put in place depends on your type of cancer. Your doctor will place the catheter or applicator into your body before you begin treatment.
There are three types of brachytherapy: Low-dose rate (LDR) implants: In this type of brachytherapy, the radiation source stays in place for 1 to 7 days. You are likely to be in the hospital during this time.
The radiation source may be kept in place for a few minutes, for many days, or for the rest of your life. How long it remains in place depends on the type of radiation source, your type of cancer, where the cancer is in your body, your health, and other cancer treatments you have had.
Dr. Williams: A small holder, usually a thin tube called a catheter, is placed into your body. Then the seeds, ribbons, or wires are put inside this small holder so that the radiation can reach and destroy cancer cells. Sona: Dr. Williams, Ravi and I have heard that there are 3 types of brachytherapy.
The source is removed after 10 to 20 minutes. This may be repeated twice a day over a few days, or once a day over the course of a few weeks.
Internal radiation therapy (brachytherapy) allows a higher dose of radiation in a smaller area than might be possible with external radiation treatment. It uses a radiation source that’s usually sealed in a small holder called an implant. Different types of implants may be called pellets, seeds, ribbons, wires, needles, capsules, balloons, or tubes.
Internal radiation is also called brachytherapy . A radioactive implant is put inside the body in or near the tumor. Getting the implant placed is usually a painless procedure. Depending on your type of cancer and treatment plan, you might get a temporary or a permanent implant.
The radioactive materials stop giving off radiation over time. It may take weeks or months. Talk to your cancer care team about how long it will take in your case. Once the radiation is gone, the implant (s) are no longer active. They usually stay in place and cause no harm, so there’s no need to take them out.
This way the radiation harms as few normal cells as possible. During intracavitary radiation, the radioactive source is placed in a body cavity (space) , such as the rectum or uterus. With interstitial radiation, the implants are placed in or near the tumor, but not in a body cavity.
The radioactive material is not left in your body. The applicator might be left in place between treatments, or it might be put in before each treatment. People getting HDR sometimes stay in the hospital if it involves multiple day treatments and if the applicator is left in place.
With internal radiation therapy, your body may give off a small amount of radiation for a short time. If you have a temporary implant, you’ll be asked to stay in the hospital and might have to limit visitors during treatment. You also may be asked to stay a certain distance away from them.
The subspecialty of oncology concerned with radiotherapy is called radiation oncologist . Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of cancerous tissue leading to cellular death.
Radiation oncology is the medical specialty concerned with prescribing radiation, and is distinct from radiology, the use of radiation in medical imaging and diagnosis. Radiation may be prescribed by a radiation oncologist with intent to cure ("curative") or for adjuvant therapy.
Total body irradiation (TBI) is a radiation therapy technique used to prepare the body to receive a bone marrow transplant.
The planning of radiation therapy treatment has been revolutionized by the ability to delineate tumors and adjacent normal structures in three dimensions using specialized CT and/or MRI scanners and planning software.
The amount of radiation used in photon radiation therapy is measured in grays (Gy), and varies depending on the type and stage of cancer being treated. For curative cases, the typical dose for a solid epithelial tumor ranges from 60 to 80 Gy, while lymphomas are treated with 20 to 40 Gy.
Radiation therapy works by damaging the DNA of cancerous cells. This DNA damage is caused by one of two types of energy, photon or charged particle. This damage is either direct or indirect ionization of the atoms which make up the DNA chain. Indirect ionization happens as a result of the ionization of water, forming free radicals, notably hydroxyl radicals, which then damage the DNA.
Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is a therapy using ionizing radiation, generally provided as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator.
In HDR brachytherapy, a high dose of radiation is delivered to the tumor in a short burst, lasting only a few minutes. Two randomized trials comparing HDR brachytherapy to whole breast radiation have found comparable outcomes and reduced toxicities as compared to whole breast irradiation.
RESTON, VA – October 18, 2018: Breast cancer represents the most common non-skin cancer among women in the United States with over 250,000 new cases each year 1. Most diagnoses represent DCIS (Ductal Carcinoma In Situ) or early stage cancers which can be safely treated with mastectomy or breast conservation. Following breast conservation, also known as lumpectomy or partial mastectomy, radiation therapy is associated with a significant reduction in the rate of recurrence in the breast, as well as the rate of dying of breast cancer 2.

It is important for women to recognize that there is no difference in survival or outcomes between mastectomy (removal of the breast) and breast conservation with multiple studies demonstrating this with long term follow up. As such, patients can preserve their breast without compromising their outcome in most cases.
The guidelines also review techniques with strong/moderate recommendations given for interstitial and applicator HDR brachytherapy. Breast HDR Brachytherapy represents a great option for appropriate patients with early stage breast cancer.
