All the women were treated sometime between and , before the ASTRO brachytherapy guidelines were released in Before preparing the treatment plan a careful evaluation of tumor size and location should be made clinical examination, mammography, ultrasonography [US], sometimes magnetic resonance imaging [MRI] , also the stage of disease should be determined according to TNM and detailed histopathological examination should be performed. With interstitial brachytherapy , several catheters are placed so that radioactive pellets can be readily inserted and removed. Average age of breast cancer patients ranges between 45 and 65, in recent years there has been a noticeable trend to lower the average age of incidence [ 1 ]. Similar conclusions were reached by Njeh et al.

Breast conserving surgery BCS with following external beam radiation therapy EBRT of the conserved breast has become widely accepted in the last decades for the treatment of early invasive breast cancer. An additional dose is given to treated volume as a boost to a portion of the breast. In the early stage of breast cancer, research has shown that the area requiring radiation treatment to prevent the cancer from local recurrence is the breast tissue that surrounds the area where the initial cancer was removed. Accelerated partial breast irradiation APBI is an approach that treats only the lumpectomy bed plus a cm margin rather than the whole breast and as a result allows accelerated delivery of the radiation dose in four to five days. There has been a growing interest for APBI and various approaches have been developed under phase I-III clinical studies; these include multicatheter interstitial brachytherapy, balloon catheter brachytherapy, conformal external beam radiation therapy 3D-EBRT and intra-operative radiation therapy IORT.
Invasive breast cancer or ductal carcinoma in situ (DCIS) 3 cm or less in size.
Radiation therapy commonly is used after lumpectomy to treat early-stage breast cancer and reduce the risk of the cancer coming back recurrence. Brachytherapy is a newer form of radiation therapy and an alternative to traditional whole-breast external beam radiation therapy. Brachytherapy delivers a higher dose of radiation to a smaller area of the breast over a shorter period of time compared to traditional external beam radiation therapy. Doctors sometimes refer to brachytherapy as accelerated partial breast irradiation APBI. In the United States, brachytherapy use has been increasing steadily since it was first approved by the U.
Brachytherapy , also referred to as internal radiation therapy, is a form of cancer treatment in which a sealed radioactive source is placed in or near a tumor to kill it. It is used to treat many different types of cancer, but is specifically used in breast cancer to clear cancer cells following a lumpectomy. Brachytherapy may also be used to reduce the size of a tumor prior to breast cancer surgery or as palliative treatment to reduce pain or bleeding in advanced or inoperable disease. Breast brachytherapy is used to treat early-stage cancers that have not spread metastasized to other parts of the body. The treatment can be delivered in different ways and is often combined with conventional external beam radiation therapy EBRT. Despite strict selection criteria, an estimated 71, American women would benefit breast brachytherapy each year, according to a review of studies in the Journal of Contemporary Brachytherapy.
