Radiation Therapy
IMRT
IGRT
Brachytherapy
Radiation Therapy is a cancer treatment that uses high-energy rays or particles to destroy cancer cells or shrink tumors. It targets specific areas while aiming to minimize damage to surrounding healthy tissue.
IMRT (Intensity-Modulated Radiation Therapy) is an advanced form of radiation therapy that uses computer-controlled beams to deliver precise doses of radiation to a tumor, while minimizing exposure to surrounding healthy tissues.
IGRT (Image-Guided Radiation Therapy) is an advanced type of radiation therapy that uses imaging techniques before and during treatment to accurately target tumors, ensuring precise radiation delivery while protecting nearby healthy tissues.
Brachytherapy is a type of internal radiation therapy where a radioactive source is placed directly inside or near the tumor, allowing high-dose radiation to target cancer cells while minimizing damage to surrounding healthy tissue.
Palliative Care
Palliative Care is specialized medical care focused on providing relief from the symptoms, pain, and stress of serious illnesses like cancer. Its goal is to improve the quality of life for patients and their families, alongside curative or life-prolonging treatments.
Stereotactic
Stereotactic Radiation Therapy is a highly precise form of radiation treatment that delivers focused, high-dose radiation to small, well-defined tumors, often in the brain or spine, with minimal impact on surrounding healthy tissue.
