Onco Radiation Treatment in Dhakuria

Our Radiation Oncology department offers a variety of cutting-edge Radiation Therapies tailored to each cancer patient's specific needs. In order to provide exact care and achieve the finest treatment outcomes while safeguarding healthy tissues, we employ cutting-edge technologies.

One of our treatments is External Beam Radiation Therapy (EBRT), which uses high-energy X-rays to target tumours. Techniques like 3D Conformal Radiotherapy (3D CRT) and Intensity-Modulated Radiation Therapy (IMRT) ensure the radiation is shaped and adjusted to the tumour, sparing surrounding tissues.

We offer Stereotactic Body Radiation Therapy (SBRT) for smaller, well-defined tumours, which provides high doses of radiation in fewer sessions, and Stereotactic Radiosurgery (SRS) for brain tumours, which offers targeted precision in a few treatments.

We also offer Brachytherapy, an internal radiation technique where radioactive material is placed near the tumour, particularly effective for prostate, cervix, and breast cancers.

Our team is dedicated to creating personalised treatment plans that focus on both effectiveness and patient comfort.

FAQ's

The main types of Radiation Therapy used in oncology include:

  • External Beam Radiation Therapy (EBRT): Targets tumours externally with high-energy X-rays or protons.

  • Intensity-Modulated Radiation Therapy (IMRT) and Volumetric Modulated Arc Therapy (VMAT): Vary the intensity of radiation to improve accuracy and reduce damage to healthy tissues.

  • Stereotactic Body Radiotherapy (SBRT) and Stereotactic Radiosurgery (SRS): Deliver high doses of radiation to small, well-defined tumours in fewer sessions.

  • Proton Beam Therapy: Uses protons to target tumours precisely, minimising harm to surrounding tissues.

  • Brachytherapy: Places radioactive sources inside or near tumours for localised treatment.

  • Total Body Irradiation (TBI): Prepares the body for transplants by delivering radiation to the entire body.

  • Intraoperative Radiation Therapy (IORT): Administers radiation during surgery directly to the tumour site.

High-energy X-rays or proton beams are used in External Beam Radiation Therapy (EBRT) to treat tumours. A linear accelerator (LINAC) or proton machine is used to administer radiation after careful planning using imaging scans (CT, MRI, PET). Multiple sessions of treatment are required to allow for the healing of healthy tissue. Treatment for malignancies of the breast, prostate, head & neck, lung, brain, rectal, and anal regions is a common use. EBRT provides a precise, non-invasive therapy method that targets tumours efficiently while protecting surrounding healthy tissues.

By varying the intensity of the radiation beam and utilising a variety of angles, Intensity-Modulated Radiation Therapy (IMRT) accurately targets tumours while minimising harm to adjacent tissues. Its sophisticated dosage distribution optimises the preservation of healthy tissues throughout therapy. Although IMRT requires more time and complexity than traditional therapy, it provides better accuracy and fewer side effects. Since this method improves treatment results, many cancer patients undergoing Radiation Therapy find it preferable.

With continuous arc supply, dynamic modulation, and shorter treatment periods than Intensity-Modulated Radiation Therapy (IMRT), Volumetric Modulated Arc Therapy (VMAT) improves treatment precision. Treatment duration is shortened while dose distribution is improved because of VMAT's capacity to dynamically modify radiation beam parameters and consider organ motion. Because of its exceptional accuracy and efficiency, VMAT is a favoured choice for many cancer patients seeking Radiation Therapy since it provides highly customised treatment regimens that are suited to each patient's needs.

Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiotherapy (SBRT) provide precise, non-invasive treatment for small tumours, with minimal recovery time. They offer high precision, short treatment duration, and effectiveness for small tumours in various body areas. However, they carry risks of side effects, have limited applicability for larger tumours or those near critical structures, require motion management for some cases, and may be costly and less available in certain areas. Despite limitations, they remain valuable options for targeted tumour treatment.

Unlike X-ray therapy, Proton Beam Therapy uses charged particles to deliver radiation, depositing energy at a specific depth into the body. It provides more accurate treatment of paediatric or sensitive regions, improved tissue sparing, and a lower risk of subsequent malignancy. Higher tumour dosages are made possible by proton therapy, which also reduces exposure to healthy tissue and may enhance treatment results. It could also call for fewer therapy sessions, which would result in shorter treatment durations overall. All things considered, Proton Beam Therapy offers accurate tumour targeting with fewer side effects, particularly in difficult instances.

Radiation Therapy, known as Brachytherapy delivers a high dosage of radiation to the tumour while limiting exposure to nearby healthy tissues by positioning radioactive sources inside or next to it. In cases of cancer of the prostate, cervix, breast, head and neck, skin, and gynaecological system, it is frequently employed. Compared to External Beam Radiation Therapy, Brachytherapy's localised method enables efficient tumour treatment with fewer side effects, making it a desirable choice for a variety of cancer types.

Intraoperative Radiation Therapy (IORT) uses a specialised device that is positioned inside the surgical field to provide a high dosage of radiation directly to the tumour bed during surgery. It is recommended for accurate radiation targeting, which lowers the danger of local recurrence. Sarcomas, gastrointestinal, gynaecological, and breast malignancies are among the common uses. Immediate Radiation Therapy following tumour removal is made possible by IORT, which improves tumour management while reducing exposure to healthy tissues. This method provides a customised strategy that may enhance treatment results and minimise negative effects.

In order to prepare patients for Haematopoietic Stem Cell Transplantation (HSCT), Total Body Radiation (TBI) is required prior to bone marrow or stem cell transplants. Immune suppression, removing damaged bone marrow, facilitating engraftment, possible anti-cancer effects, and improving transplant outcomes are among the main functions of TBI. It's essential to conditioning protocols since it promotes effective engraftment and enhances post-transplant results. TBI is critical to the preparation of HSCT because of its capacity to alter the recipient's immune system and eliminate any remaining cancer cells.
