Radiotherapy uses targeted radiation to kill cancer cells. It can be used at different stages of treatment.
Oncology Consultants offers the most advanced standard of radiation therapy. Using localized high-energy rays, we can combat cancer cells and eradicate visible tumors, preventing them from growing and dividing, while minimizing side effects.


The radiation is delivered by a sophisticated machine called, Linear Accelerator. The machine has with image guidance technologies and stereotactic capability. We utilize advanced Cone Beam CT (CBCT) image guidance and Intensity Modulated Radiation Technology (IMRT) combined with non-invasive Stereotactic Ablative Radiation Therapy. Treatment Planning simulation for radiation therapy is performed using GE CT Discovery RT Gen 3 equipped with respiratory gating which enables 4-D planning for superior radiation treatment targeting.




Radiation therapy, also known as radiotherapy, is a common medical treatment used to treat various conditions, including cancer. It involves the use of high-energy x-rays that travel in a linear fashion to target and destroy cancer cells or shrink tumors. Here's what you can generally expect when undergoing radiation therapy:


Consultation and Planning: Before starting radiation therapy, you'll meet with a radiation oncologist who will review your medical history, conduct physical exams, and possibly order imaging tests such as CT scans or MRI to precisely locate the tumor. A treatment plan will be developed based on the type, size, and location of the tumor. 


Simulation: During this step, you will undergo a simulation session where the treatment team will help you get into the exact position you'll be in during each radiation session. This helps ensure accurate targeting. The team will construct immobilization devices and place small marks (the size of a freckle) on your body to help algin your body in the same position for each treatment.


Treatment Schedule: Radiation therapy is usually given over a series of sessions, called fractions, which are spread out over several days or weeks. The number of sessions will depend on the type and stage of cancer, as well as the treatment goals. Most people receive radiation therapy as an outpatient procedure, meaning you can go home after each session.


Treatment Sessions: Each radiation therapy session is typically quick, usually lasting about 15 to 30 minutes. The actual radiation delivery takes only a few minutes, with most of the time spent ensuring precise positioning. You'll lie on a treatment table, and the machine delivering the radiation will be adjusted to target the tumor accurately. You will not be radioactive after treatment. 


Side Effects: Radiation therapy affects both cancerous and healthy cells in the treatment area. Side effects can vary widely based on the location of treatment, the dose, and your individual sensitivity. Common side effects include fatigue, skin changes (redness, itching, or peeling), hair loss in the treatment area, and changes in the blood count. Your radiation oncology team will closely monitor your progress and manage side effects.


Managing Side Effects: Your radiation oncology care team will provide guidance on managing side effects. They might recommend creams or ointments for skin irritation, suggest dietary changes to combat nausea, or provide pain management strategies if necessary.


Follow-Up: After your course of radiation therapy is completed, you'll have follow-up appointments with your radiation oncologist to monitor your progress and assess the treatment's effectiveness. Additional tests or imaging may be ordered to evaluate the tumor's response to treatment. 


It is important to have open communication with your radiation oncology team about any side effects or concerns you have during the treatment process. Everyone's experience with radiation therapy is unique, but the Oncology Consultants radiation oncology team is there to guide you and provide support throughout the treatment journey.
