Radiation therapy treatment
Radiation therapy uses high-energy radiation to target and destroy cancer cells. It’s used in the early stages of cancer treatment or after it has started to spread. The goal of radiation therapy is to deliver precise doses of radiation to the tumor while minimizing damage to healthy surrounding tissues.
Radiation therapy for cancer
At GenesisCare, we use the latest-generation machines to deliver highly targeted radiation beams. The accuracy of these treatments, together with the expertise of our teams, helps our patients achieve the best possible outcomes. The type of radiation treatment your physician recommends will depend on your diagnosis, if the cancer has spread to other parts of your body, your general health and personal preferences.
What to expect during radiation therapy
Accelerated Partial Breast Irradiation
An advanced radiation therapy technique used after breast conserving surgery for early breast cancers.
CyberKnife Robotic radiation therapy
CyberKnife is a highly advanced radiation therapy system which uses an intelligent robot to deliver radiation beams from over 200 carefully selected angles to ensure your tumor is precisely targeted and important normal structures and tissues protected. The intelligent part of the robot can track movement as it happens in the body and make the necessary adjustments for even greater precision. CyberKnife is available at key locations across the GenesisCare network. You should discuss the role of CyberKnife with your Oncologist. Access and support can be arranged if required.
Electronic brachytherapy is a type of radiation therapy that delivers localized radiation treatment using a machine that generates low-energy X-rays. It is an alternative to traditional brachytherapy, which involves the insertion of radioactive sources directly into or near the tumor.
External beam radiation therapy
EBRT is delivered from outside of the body and aims an accurate x-ray beam from multiple angles directly toward the treatment site. It is typically performed on an outpatient basis, so there’s no hospital stay required, usually once a day over the course of a few weeks.
Gamma Knife is a type of stereotactic radiosurgery (SRS) and uses tiny beams of gamma radiation to treat tumors, vascular malformations and other abnormalities of the brain with sub-millimeter precision to avoid damage to healthy brain tissue. It is often used to control secondary brain cancer – where cancer has spread to the brain from a primary cancer – and for tumors that can’t easily be reached with surgery. Gamma Knife is delivered in an outpatient setting and no anesthesia or overnight hospital stay is needed. Most treatments are delivered in around 45 minutes and only require one to three sessions.
High-dose rate (HDR) brachytherapy
HDR brachytherapy is a type of radiation therapy that involves the delivery of a highly concentrated dose of radiation to the tumor in a short period of time. This is achieved by temporarily inserting a high-activity radioactive source into or near the tumor, allowing for precise and intense radiation treatment while minimizing the duration of exposure.
Intensity-modulated radiation therapy (IMRT)
IMRT is an advanced external beam radiation therapy technique where the beams of radiation are precisely shaped to exactly match your tumor, which limits radiation exposure to adjacent healthy tissue.
Image-guided radiation therapy (IGRT)
IGRT is a radiation therapy technique that involves the use of imaging technology to guide and adjust the delivery of radiation treatment. IGRT allows for real-time imaging of the tumor and surrounding structures, helping to ensure accurate targeting of the radiation beams and accounting for any changes in your anatomy or tumor position during treatment.
Keloid are scars in which the scar-forming tissue has overgrown. They are benign (non-cancerous), and are typically lumpy and raised. They are often painless but may be tender or itchy. While the cause is not fully understood, they are often associated with a skin injury, such as surgical incision, piercing, burn, scratch, cut, injection or bug bite. Keloids do not turn into cancers and are not contagious.
Low-dose rate brachytherapy
LDR brachytherapy is a type of radiation therapy that involves the placement of radioactive sources near or within the tumor for an extended period of time, typically several days. The radiation is delivered at a continuous, low-dose rate, allowing for gradual and targeted treatment of the tumor while minimizing exposure to surrounding healthy tissues.
MRI-guided radiation therapy (MRIgRT)
MRIgRT is an advanced technique that combines magnetic resonance imaging (MRI) and radiation therapy in a single system. MRIgRT allows for real-time imaging of the tumor and surrounding tissues during radiation therapy, enabling precise targeting and adaptation of the treatment to changes in the your anatomy or tumor position.
The MRIdian®'s smart technology combines high-resolution magnetic resonance imaging (MRI) techniques with extremely precise radiation beams that can treat tumors more accurately than conventional radiation therapy. This can mean fewer treatment sessions, reduced side effects and a greater chance of an improved outcome.
MRIdian® is suitable for:
PET CT Imaging
A PET/CT scan is a precise diagnostic imaging technique that combines a PET scan and a CT scan to create detailed 3D images of the inside of your body to help identify the location of your cancer. We use PET/CT scans for many types of cancer and during different parts of your cancer journey. It is more accurate in diagnosing cancer than a PET scan or CT scan alone.
Prostate specific membrane antigen (PSMA PET)
Electronic brachytherapy is a skin cancer treatment that delivers a targeted dose of X-ray radiation to the cancer site through a probe on your skin. Benefits of this procedure included excellent cosmetic outcomes and minimal side effects, making it a great alternative to surgery.
Stereotactic body radiation therapy (SBRT)
SBRT is a type of radiation therapy that delivers highly focused and precise radiation to tumors located in various parts of the body, including the lungs, liver, spine and prostate. SBRT utilizes advanced imaging techniques, such as CT scans and MRI, to precisely target the tumor while minimizing radiation exposure to surrounding healthy tissues and typically involves delivering larger doses over radiation over a shorter period of time compared to conventional radiation treatments.
Stereotactic radiosurgery (SRS)
SRS is an advanced radiation therapy technique that provides non-surgical treatment that delivers a high dose of radiation precisely to a targeted area within the brain or other parts of the body. Despite its name, SRS is not a surgical procedure but rather a highly focused and precise form of radiation therapy that can effectively treat small tumors or lesions while minimizing damage to surrounding healthy tissues.
Surface-guided radiation therapy (SGRT)
Surface-guided radiation therapy (SGRT) including deep inspiration breath hold (DIBH)
SGRT is a non-invasive technique that uses real-time imaging technology to track and monitor the position of your skin surface during radiation therapy, ensuring accurate and precise delivery of radiation to the treatment area.
Tomotherapy is a type of intensity-modulated radiation therapy (IMRT). It combines the technologies of a CT scanner and a linear accelerator machine to provide three dimensional (3D) images that help to accurately target a tumor.
Volumetric modulated arc therapy (VMAT)
VMAT is an advanced radiation therapy technique that works by delivering a continuous arc of radiation around your body, rather than individual beams typically used by other forms of radiation. As the machine (called a LINAC) moves, it automatically changes the beam shape and treatment dose.
