Radiation therapy uses high energy radiation to shrink tumors and kill cancer cells. Radiation therapy kills cancer cells by damaging their DNA directly or creates charged particles within the cells that can in turn damage the DNA. Radiation therapy can damage normal cells as well as cancer cells. Therefore, treatment must be carefully planned to minimize side effects. In our hospital some patients receive radiation therapy alone, and some receive radiation therapy in combination with chemotherapy.
Radiation therapy may also be given with palliative intent. Palliative treatments are not intended to cure. Instead, they relieve symptoms and reduce the suffering caused by cancer. Our radiation oncologists develop a patient’s treatment plan through a process called treatment planning, which begins with simulation. During simulation, detailed imaging scans show the location of a patient’s tumor and the normal areas around it. These scans include Computed tomography (CT) scans, Magnetic resonance imaging (MRI), Ultrasound scans, Positron emission tomography (PET). After simulation, the radiation oncologist then determines the exact area that will be treated, the total radiation dose that will be delivered to the tumor, how much dose will be allowed for the normal tissues around the tumor, and the safest angles (paths) for radiation delivery. The area selected for treatment usually includes the whole tumor plus a small amount of normal tissue surrounding the tumor.
The type of radiation therapy prescribed by a radiation oncologist depends on many factors, including:
- The type of cancer.
- The size of the cancer.
- The cancer’s location in the body.
- How close the cancer is to normal tissues that are sensitive to radiation.
- How far into the body the radiation needs to travel.
- The patient’s general health and medical history.
- Whether the patient will have other types of cancer treatment.
- Other factors, such as the patient’s age and other medical conditions.
We are also providing external-beam radiation therapy treatments like 3-dimensional conformal radiation therapy (3D- CRT), tomotherapy etc. These are done using very sophisticated computer software and advanced treatment machines to deliver radiation to very precisely shaped target areas. Patients can discuss these different methods of radiation therapy with their doctors to see if any is appropriate for their type of cancer and if it is available. Other methods are internal radiation therapy or brachytherapy in which radiation is delivered from radiation sources (radioactive materials) placed inside or on the body. Several brachytherapy techniques are used in our hospital for cancer treatment. Brachytherapy may be able to deliver higher doses of radiation to some cancers than external-beam radiation therapy while causing less damage to normal tissue.
Systemic radiation therapy is another method of radiation treatment that we are offering in which a patient swallows or receives an injection of a radioactive substance, such as radioactive iodine or a radioactive substance bound to a monoclonal antibody. In systemic radiation therapy for some types of cancer, a monoclonal antibody helps target the radioactive substance to the right place. The antibody joined to the radioactive substance travels through the blood, locating and killing tumor cells
A patient may receive radiation therapy before, during, or after surgery. Some patients may receive radiation therapy alone, without surgery or other treatments. Some patients may receive radiation therapy and chemotherapy at the same time. The timing of radiation therapy depends on the type of cancer being treated and the goal of treatment. At Guru Multispecialty hospital our doctor or nurse will provide more information to the patient and family members and caretakers if any of the special precautions are needed during the radiation treatment.
Our multimodelihed and individualized approach to radiation therapy offers the best results. We use Elekta Synergy system, a high-end linear accelerator that is fast and precise. Multiple imaging options and advanced registration tools make the treatment highly effective.
