What is the procedure of radiotherapy?

During external beam radiation therapy, you’re positioned on a table and a large machine moves around you sending beams of radiation into precise points in your body. External beam radiation therapy is usually conducted using a linear accelerator — a machine that directs high-energy beams of radiation into your body.

What type of radiation is used in radiotherapy?

Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells.

Does radiotherapy for breast cancer have any side effects?

Conclusion • Radiotherapy remains a key tool in the treatment of breast cancer and in reducing the incidence of recurrence. • Whilst side effects of nausea, vomiting and skin erythema are common, new techniques are reducing toxicity.
