Why does photodynamic therapy reduce the recurrence rate? Photodynamic treatment of acromegaly is a relatively new method, although the light source is a laser. The operation is to first apply a photosensitizer to the affected area and leave it for more than three hours. These photosensitizers will be fully absorbed by the growing tissues, after which the photosensitizers will undergo a photochemical reaction to selectively kill these tissue cells under a specific laser irradiation; while the physical laser treatment is often said to remove the warts directly with a high-energy laser. Compared to other physical treatments, speed is the disadvantage of photodynamic therapy – each treatment takes at least half a day, usually three times for a course of treatment; its biggest advantage is the low recurrence rate, physical therapy can only remove the “head” of the wart, that is In general, physical therapy has a higher recurrence rate, but photodynamic therapy, the recurrence rate is only about 10%. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. Can every patient undergo photodynamic therapy? What if I have other STDs at the same time? Photodynamic therapy can treat a wide range of areas, including the perianal area, genitalia and other exposed areas, as well as the deep oral mucosa and cervix. However, pregnant women should use it with caution. Although theoretically there is no effect, after all, photodynamic therapy will have some stinging and may affect pregnancy, and other effects cannot be ruled out, the data in this regard is not sufficient. If you are suffering from gonorrhea, as the treatment cycle of this disease is not long, you can control the disease first and then do photodynamic; if you are suffering from syphilis with hard chancre, you need to control it as soon as possible and then consider photodynamic afterwards; if you are suffering from second-stage syphilis, as the two diseases do not affect each other much, you can treat photodynamic and intramuscular benzathine penicillin at the same time or after the second-stage syphilis treatment. Does photodynamic therapy hurt? During photodynamic therapy, there will be a slight tingling at the irradiated area, and very few patients will have obvious pain, which is a normal reaction to the treatment, and this pain will gradually disappear in 1-2 days after the treatment, and pain medication can be given if necessary. After one or two days of photodynamic therapy, there may be flushing, edema and ulcers on the trauma and surrounding skin, which are normal.
