FIRST TESTS TO PREDICT A PATIENT’S RADIOSENSITIVITY

NovaGray develops and commercializes the first radiotherapy tolerance tests for patients treated for breast or prostate cancer.

Performed before the start of radiotherapy with a simple blood draw, the tests assess the patients’ individual radiosensitivity and determine their risk of developing late complications after radiotherapy.

WHY DO A RADIOSENSITIVITY TEST?

Knowing a patient’s individual radiosensitivity is important information that can help:

  • Reassure the patient in preparation for radiotherapy
  • Guide physicians in choosing the most appropriate treatment plan
  • Adapt patient follow-up after radiotherapy
