The advantage of this method is that the radiation works directly within the malignant tissue. Due to the proximity of the area to be treated to the radiation source, the fall-off of the radiation dose in the surrounding tissue is much higher than with teletherapy. That’s why a higher radiation dose can be applied in a very short amount of time with brachytherapy. The entire duration of the treatment is generally reduced from six weeks to approximately one week.
A further advantage is the significantly lower radiation exposure for the patient compared with other radiotherapies. Even with an advanced tumour or with the recurrence of a tumour following normal radiotherapy, brachytherapy on its own or in connection with normal radiotherapy and/or chemotherapy has considerable advantages.
