Advanced radiotherapy for rectal cancer – Alexander Valdman's team

We conduct clinical research focused on advanced radiotherapy for rectal cancer, with a particular emphasis on organ-preserving treatment for early-stage disease. By developing and evaluating local, individualised radiotherapy techniques, including contact brachytherapy as well as photon and proton therapy, we aim to reduce side effects and improve treatment outcomes. The goal is to enable more patients to be cured without surgery, while maintaining quality of life.
