Prevent Cancer Using Photodynamic Therapy Having cancer will likely be the most terrifying time of your life. Thankfully, there are increasingly medical advances in the fight against cancer emerging all of the time. This means that there will hopefully be a treatment available that will effectively fight your cancer & send you in to remission. One treatment used in the fight against cancer is called Photodynamic Therapy. This treatment is matchless because it combines the use of light & a specific drug to target cancer cells. The drug that is used in this treatment is called a photosensitize, which when combined with a specific wavelength of light, will produce a kind of oxygen that actually kills cells. Your doctor can give you all of the specifics on how the treatment works. As with any cancer treatment, there are both risks & benefits of using Photodynamic Therapy in London.
