What is Radiation Therapy?
Radiation therapy is a cornerstone treatment for cancer that uses high-energy rays (X-rays, gamma rays, or protons) to destroy cancer cells by damaging their DNA, thus preventing their ability to multiply. It is employed either as a primary therapy, adjuvant to surgery or chemotherapy, or palliative care to relieve symptoms in advanced cases.
Depending on the location, size, and type of cancer, various techniques may be used:
- External Beam Radiation Therapy (EBRT) – targets tumours using machines like linear accelerators; includes advanced forms like IMRT, IGRT, and proton therapy for precision.
- Internal Radiation (Brachytherapy) – involves implanting radioactive material inside or near the tumour.
- Stereotactic and Robotic Systems (e.g., CyberKnife) – offer highly focused treatment with fewer sessions and minimal tissue damage.
While effective, radiation therapy may cause side effects such as fatigue, skin irritation, nausea, and site-specific symptoms like urinary discomfort, mouth ulcers, sore throat, or fertility issues. However, modern techniques now significantly minimize these side effects by sparing healthy tissue.
Why Choose India for Radiation Therapy?
India—particularly Delhi’s Tier 1 private hospitals like Apollo Hospitals, Fortis Healthcare, Max Super Speciality Hospital, and BLK-Max Hospital—is a top destination for cancer care due to its:
Globally trained oncologists and multidisciplinary cancer teams experienced in both standard and advanced radiation techniques
- State-of-the-art equipment including proton therapy, IMRT, IGRT, and CyberKnife systems
- Integrated cancer care with support services like nutritional therapy, counseling, and palliative care
- Robust support for international patients: medical visas, language interpreters, airport pickup, and personalized treatment coordinators
Most notably, India provides radiation therapy at one-fifth to one-seventh the cost of the US or UK without compromising safety or outcomes.
