Optimization of the applicators position is very important for uniform dose distribution in the case of lip cancer treated using brachytherapy methods. Depending on the patient's anatomical data there are several possible positions of the applicators at different distances. The criterion of the choice of the best positions can be based on the tumour control probability concept that naturally takes into account both physical dose distribution and radiobiological effects. In this work, we present

According to our investigations the optimal distances amounted 9 and 10 mm between implants.
