📖About External Beam Radiotherapy
External beam radiotherapy delivers precisely focused high-energy X-ray beams from outside the body to destroy cancer cells while minimising damage to surrounding healthy tissue. It is one of the most widely used cancer treatments, given either alone or combined with surgery and chemotherapy depending on tumour type and stage. Modern linear accelerators use imaging guidance to target tumours with millimetre precision. Treatment is typically delivered in fractionated daily doses over several weeks to allow healthy cells time to recover between sessions.
