Department mission

The radiotherapy department treats using X-rays, which enables cancerous cells to be progressively destroyed. Healthy cells are also affected, but their resistance and capacity for recovery means they repair themselves between each session. This is why the prescribed dose is administered over several sessions. Their number is adapted based on each patient’s specific case. Each treatment is personalised.

Treatment by radiotherapy comprises several phases and involves different professionals at the centre (radiation oncologists, medical interns, medical physicists, dosimetrists, medical radiation technicians, nursing auxiliaries, paediatric coordinator, healthcare executive, dietician, medical secretaries, biomedical technicians, hospital housekeepers).

Healthcare offer and expertise

The radiotherapy department’s activity includes radiation treatment for adults and children. Treatment modalities include:
