Radiotherapy is one of the most commonly used cancer treatments. It requires a great deal of precision and must be carefully adapted to each patient.

When a cancer patient is identified as requiring radiotherapy, a treatment plan is drawn up by an oncological radiotherapist during the first radiotherapy consultation. This determines the best treatment strategy, the most appropriate radiotherapy equipment, the expected number of sessions, and the treatment duration.

Every radiation treatment requires a period of preparation, during which specialists make a precise calculation of the volumes to be irradiated, by means of different imaging tests. These images are also used to locate the healthy organs adjacent to the treated area and to draw up a personalized treatment plan for each patient.

Quality controls are essential to ensuring that the treatment is delivered precisely and under the best possible conditions, so that it can work effectively. The estimated dosage is prepared by dosimetrists and validated by oncological radiotherapists, while the treatment plan parameters are checked by a medical physicist.

The positioning of the patient on the treatment table is carefully checked every day. The dose actually received is systematically measured and compared to the planned dose. The treatment parameters and follow-up tests are monitored and checked. Weekly medical consultations take place throughout the treatment so the patient can be monitored by a physician.
