We not only diagnose but also treat patients using least invasive techniques. The treatments offered at Gleneagles Global Hospitals minimize the patient risk and help them recover soon and lead a healthy life.
Some of the interventional radiology procedures include:
The radiation therapy plays an important role in killing the cancer cells and preventing the further growth of the cancer cells. We at Gleneagles Global Hospitals take care of this and provide you with the best treatment for you to live a healthy and a happy life.
Highlights of Radiation Oncology:
The high-energy ionizing radiation used in this type treatment for cancer kills the malignant cells by destroying their DNA; thereby preventing their further growth.
Radiation therapy may bring few temporary side effects such as dry skin, itching, blisters. The instant effects may be nausea, vomiting etc. There could also be long term side effects of this treatment.
There are various machines for giving radiation therapy for cancer. The more advanced machines such as TrueBeam STx can destroy the cancer cells with ultrafine (sub millimeter) precision.
We measure our progress by the number of people in whom we restore the hope of a healthy tomorrow. Our doctors are highly knowledgeable, skilled, compassionate and will be there for you when you need them the most.
Streamlined processes, advanced technologies, state-of-the-art infrastructures, specialised & interdisciplinary care and an unparalleled simplicity for meeting every patient's health needs. We are committed to your well-being.
Providing global access to advanced healthcare. We embrace high precision technologies for giving you a world class healthcare experience. Our exceptional medical expertise is matched by our commitment to personalised care.
Brachytherapy is also called as internal radiation therapy. It is the treatment of the prostate cancer. Brachytherapy places the radioactive particles inside the patient on a temporary or a permanent basis to damage the DNA of the cancer cells and also to destroy their ability to divide and grow. The dose of radiation used to treat a particular area of the body varies from person to person. It allows the doctor (radiologist) to use a higher total dose of radiation to treat a smaller area in less time. There are two types of brachytherapy, they are permanent brachytherapy and temporary brachytherpy.
In permanent brachytherapy, needles are pre-filled with radioactive seeds and are inserted into the tumor. In temporary brachytherapy, a delivery device, such as a catheter, needle, or applicator, is placed into the tumor using imaging techniques such as fluoroscopy, ultrasound, MRI or CT to help position the radiation sources. The delivery device is inserted into the vagina or uterus (intracavitary brachytherapy). Treatments may be delivered at a high dose-rate over 10 to 20 minutes per session or a low dose-rate (LDR) over 20 to 50 hours. Treatment may also be delivered in periodic pulses.
External Beam Radiation Therapy (EBT) is a radiation therapy for delivering high-energy x-ray beams to a patient’s tumor. EBT may also be used to relieve symptoms in patients with advanced cancer or cancer that has metastasized. In external beam radiation no radioactive sources are placed inside the patient's body.
The patient will be asked to change into the hospital gown. A few of the imaging techniques are used prior to the treatment to verify the accuracy. The therapist turns on the machine and the beams from one or more directions may be used for the treatment. The part to be studied is exposed to the beam for as long as several minutes for each field. The duration of a patient's treatment depends on the method of treatment delivery and the dose given. The length of each treatment will usually be the same from day to day.
Systemic Radiation Therapy is a type of radiation therapy in which radioactive materials are inserted which travel through the bloodstream to the targeted cells in the body. Systemic radiation is used to treat certain types of cancer (e.g. thyroid cancer) to relieve pain when cancer spreads to the bone. The radiation sources are in the form of a liquid which are made up of a radioactive substance, sometimes bound to a special antibody that attaches to the cancer cells.
The radioactive materials (iodine I-131) may be delivered in different ways such as oral administration, intravenous injection or instillation. The dose of systemic radiation treatment is different for each person. It will depend on the type of cancer being treated.
