What is photodynamic therapy?

Hello,

Welcome to icliniq.com.

I understand your concern.

Photodynamic therapy is a light-sensitive treatment used for various skin and other cancer tumors. This approach works by destroying tumors through free radicals generated during the process. The therapy involves three key steps: first, a light-sensitive drug is applied; second, there is an incubation period; and third, light of a specific wavelength is applied. This method effectively targets and destroys tumor cells while minimizing damage to DNA (deoxyribonucleic acid) material.

Side effects of photodynamic therapy include:

1. The eyes and skin may become light-sensitive for up to 6 weeks after treatment due to the drug.
2. Other side effects may include pain, swelling, and scarring.

Advantages of photodynamic therapy include:

1. Less invasive compared to surgery.
2. No long-term side effects.
3. Does not cause scars that do not heal.
4. Targets only specific cells.
5. Requires fewer repeat treatments.
6. Less expensive than other cancer therapies.

Feel free to follow up with any questions.

Thanks for using icliniq, and have a nice day.
