How does radiation kill breast cancer cells?

Susan McCloskey, MD
Radiation Oncology
Radiation therapy consistently decreases the risk for breast cancer recurrence by about 50% to 70%. This does not only affect local recurrence but also has a breast cancer-specific survival benefit. Radiation therapy works by damaging the DNA of cancer cells, which is the genetic material that cancer itself uses to grow and divide. Cancer cells can’t repair that damage, so they die. Radiation therapy takes about 10 minutes a day, and a typical course of radiation is about six and a half weeks on average.
