Photodynamic therapy causes Cancer cells to self destruct.

Scientists just discovered that zapping cancerous cells with light after injecting them with a particular chemical causes them to commit “cell suicide”.

This technique called Photodynamic therapy kills cancer cells in 2hours, the chemical compound injected is Nitrobenzaldehyde which makes the cell to acidic to survive and the light is what activates the reaction. Clinical trials with laboratory mice has already yielded a 95% success rate.

There are many different types of cancers. The only thing they have in common is their susceptibility to this induced cell suicide. We are thinking outside the box and finding a way to do what for many is simply impossible.

Professor Matthew Gdovin

From experiments, it’s been seen that a single treatment doubled the chances of survival in the mice, it is also showing positive results against the aggressive triple negative breast cancer.

The study by a group of individuals in the University of Texas at San Antonio, could help towards developing treatment for humans, who knows, the non-invasive nature of this technique could make it just what is needed to treat hard-to-reach cancers like cancer of the spine or brain stem.


Photodynamic therapy (PDT) is a treatment that uses a drug, called a photosensitizer or photosensitizing agent, and a particular type of light. When photosensitizers are exposed to a specific wavelength of light, they produce a form of oxygen that kills nearby cells (1–3).
