Many patients feel anxious before their first session. Understanding the process and possible effects can help you feel more prepared and confident.<\/p><h2><span style=\"font-size: 24px;\"><b>Does radiotherapy hurt? Is it dangerous?<\/b><\/span><\/h2><p class=\"translation-block\">Radiotherapy is painless. During treatment, you simply lie still on the treatment table while the machine moves around you. The actual radiation delivery usually takes 5\u201315 minutes.<\/p><p class=\"translation-block\">It is a localized treatment planned carefully to minimize effects on surrounding healthy tissue. Importantly, radiotherapy does not leave radiation in your body, and it is safe to be around others.<\/p><h2><span style=\"font-size: 24px;\"><b>Will you feel anything on the first day?<\/b><\/span><\/h2><p class=\"translation-block\">Most patients do not feel immediate side effects on the first day.
