Team of Drs. Fortýn, Horák, et al tests Devitalization of Tumors on mammals in the 32nd year




    My basic information

    My brief definition of Devitalization of Tumors

    My phone directory
Dr. Fortýn, inventor of devitalization of tumors, practiced it for 44 years on humans, and also for 30 years on animals.

By creating this website, I want to contribute to better informedness on the devitalization of tumors.  
I am grateful for all materials.   You may copy and pass on to others everything that you find here, if you will only quote its source and authors.  I genuinely welcome any information, comments, and suggestions you may have on this issue, as, I sincerely believe that all the evidence indicates the technique´s potential to save lives.
