11. Optimizing cervical cancer prevention through screening and HPV vaccination
Abstract : Effective primary and secondary prevention tools exist for cervical cancer in the form of human papillomavirus (HPV) vaccines and cervical screening. In order to maximize the impact of prevention strategies in Sweden and European countries, this thesis sought to investigate the long-term effectiveness of different screening strategies and the long-term risk associated with HPV infections, the organization and quality of existing screening programs, and the effectiveness of alternative vaccination strategies.

12. Development of Experimental Brachytherapy Dosimetry Using Monte Carlo Simulations for Detector Characterization
Abstract : Brachytherapy (BT) is a type of interventional radiotherapy that is advantageous due to high absorbed dose conformity and possibility to deliver high dose in few fractions. It is often used for prostate and gynecological tumors as monotherapy or a boost alongside external beam radiotherapy (EBRT). READ MORE

14. Helical tomotherapy for total marrow and total skin irradiation : Optimisation, verification, and clinical results
Abstract : In modern cancer therapy, radiotherapy (RT) is a vital part of most treatments. Most RT treatments in Sweden are performed using intensity-modulated radiotherapy (IMRT) with fixed or dynamic arc delivery. The dose gradients outside the target are steep, the margins are small, and the treatment delivery is complicated. READ MORE
