Of course, this also shows the fundamental difference to conventional therapies. First, during an operation is the tumor removed from the body and thus also important information for the immune system. Second, this is a major trauma that provokes inflammation and the release of growth hormones that encourages still present cancer cells to grow. With the, through the urethra guided, heat treatment dies the tumor within the organ and the surrounding healthy tissue is not damaged and remains fully functional. The body's own immune system is stimulated to recognize and battle the tumor. The usual side effects of surgery and radiation do not occur in hyperthermia. Even for these reasons alone, hyperthermia is a real alternative to „watchful waiting“. In other words, for the qualified patient it is still better to conduct an effective method with few side effects than to wait and see if the tumor is growing, even when for this approach studies with larger numbers are still pending. The patient's quality of life is improved by it, especially while potency problems and urinary incontinence do not occur with hyperthermia. Given the fact that so far none of the conventional therapies offer significant survival advantage for prostate cancer patients, it may be difficult to impose a specific invasive procedure with irreversible damage on a patient. Rather, the patient should have a say in what he wants, especially when you take into consideration the possibility of a dramatic impairment life quality.
