Photodynamic therapy

Light-activated drug that selectively destroys cancer cells.

What it is

Photodynamic therapy (PDT) is a treatment that uses light to kill cancer cells. It works by using a light-sensitive medication that is activated by a specific wavelength of light, which then produces a form of oxygen that damages cancer cells.

What research shows

Studies suggest that PDT can be effective in treating various types of cancer, including skin, bladder, and gynecological tumors. Clinical trials have shown that PDT can lead to tumor response rates and improved local control, although more research is needed to fully understand its effects. Patient populations studied have included those with skin cancer, bladder cancer, and gynecological tumors.

Current status

PDT is a treatment option that is being explored for various types of cancer, but its use is still limited and more research is needed to fully understand its effects and optimal applications. Further studies are required to determine its efficacy and safety in different patient populations.
