Radiation Therapy (Radiation Oncology) in Udaipur

Understanding the Disease & Treatment Mechanics

Radiation therapy can be delivered as primary curative treatment, neoadjuvant therapy (before surgery to shrink bulky tumors), adjuvant therapy (after surgery to eliminate microscopic residual disease), or palliative therapy to alleviate tumor pressure and pain. Every treatment plan is meticulously calculated using 3D Conformal Radiotherapy (3D-CRT) or Intensity-Modulated Radiation Therapy (IMRT) techniques. This spatial precision ensures high therapeutic doses are delivered to the target volume while sparing critical surrounding structures such as the optic nerve, spinal cord, salivary glands, heart, and lungs.

Treatment Approach & Clinical Protocols

The treatment journey begins with a comprehensive consultation and review of all diagnostic PET-CT, MRI, and biopsy reports. Next, the patient undergoes a CT Simulation scan in the radiation oncology department. Custom immobilization devices—such as thermoplastic head-and-neck masks or vacuum cushions—are crafted to guarantee sub-millimeter positional reproducibility during daily treatments. Radiation oncologists and medical physicists then delineate target contours and organ-at-risk boundaries on treatment planning software. Daily sessions last approximately 15 to 20 minutes, during which the patient lies comfortably on the treatment couch while the machine rotates around them without causing physical pain.

Common Indications & Applications

• Head and neck carcinomas (oral cavity, larynx, pharynx)
• Breast cancer radiotherapy (post-mastectomy and breast-conserving surgery)
• Gynecological cancers (cervical, uterine, vaginal)
• Gastrointestinal & thoracic tumors (esophagus, lung, rectum)
• Central nervous system & brain tumors
• Palliative radiation for bone metastases and painful nerve compression

What Patients Should Expect

Initial consultation includes physical exam, imaging verification, and simulation scheduling. Daily treatment fractions are delivered 5 days a week over a 2 to 7 week period, depending on whether the intent is curative or palliative.

Recovery, Side Effect Management & Hygiene

Radiation side effects are localized strictly to the body region being treated. Common transient acute effects include mild skin erythema (similar to sunburn), localized fatigue, and mild swelling. For head and neck radiation, patients may experience mucositis or dry mouth (xerostomia); for pelvic radiation, transient bowel or bladder frequency may occur. Dr. Narendra Rathore provides structured supportive protocols including specialized skin barrier gels, oral lubricating rinses, dietary modifications, and hydration targets to minimize side effects and ensure smooth treatment completion.
