1. Minimally invasive: With the intervention of optical fiber, endoscope and other technologies, the laser is guided to the deep part of the body for treatment, avoiding the trauma and pain caused by thoracotomy and laparotomy. 2. Selectivity of treatment area: The main target of photodynamic therapy is the diseased tissue in the light area, which has no damage to the normal tissue at the bottom and surrounding of the lesion. This selective killing behavior cannot be achieved by other conventional means. Because the photosensitizer is only absorbed and retained by diseased cells, there is no systemic toxicity, and the action light wave is not absorbed by normal tissues, so the treatment is only aimed at diseased tissues, which ensures that normal tissues are not damaged. 3. Validity: vascular injury caused by photodynamic action and local ischemia and hypoxia of diseased tissues,
Finally, the lesion was killed. And because of the strong drug localization in the treatment process. It can be automatically generated in various parts of virus warts and herpes, and at the same time, it can enhance the body's own immune mechanism, prevent recurrence or metastasis, and has good treatment effect and low recurrence rate.
4. No drug resistance, toxic and side effects: As the preparation itself is non-toxic, it will be metabolized quickly after entering the human body, and it will not generate accumulation in the body, and the body will not produce drug resistance to photosensitive preparations. Therefore, photodynamic therapy can be used repeatedly.
5. Flexibility: Photodynamic therapy is not limited by other therapies, and can be used alone or in combination with other therapies.
6. Non-invasive: the epithelial structure and collagen scaffold of the diseased organ are less damaged, so that the appearance and functional integrity of the organ can be maintained after the wound is healed. The treatment does not require surgery, hospitalization, short treatment time, no trauma and no pain. (official website: Demei Clinic)
