A CANCER expert has hit on a way to kill tumours in two hours — using light.
The technique involves a single jab with a chemical then a flash of ultraviolet.
The technique called ‘photodynamic therapy’ kills cancer cells in mice in under two hours using a chemical combination and ultraviolet.
Professor Matthew Gdovin revealed the cells — which he injected with the chemical compound nitrobenzaldehyde — turned too acidic to survive.
His lab tests showed amazing results against triple negative breast cancer — one of the most aggressive forms.
Just one treatment stopped tumours growing, doubling chances of survival.
Prof Gdovin, of the University of Texas at San Antonio, said that because the treatment is non-invasive it is ideal for hard to reach cancers such as in the spine or heart.

Good to see you back.
Thanks for the thread info, I will have to research it a little more.
Porfimer sodium, sold as Photofrin, is a photosensitizer used in photodynamic therapy and radiation therapy and for palliative treatment of obstructing endobronchial non-small cell lung carcinoma and obstructing esophageal cancer.
Porfimer is a mixture of oligomers formed by ether and ester linkages of up to eight porphyrin units. In practice, a red light source emitting at 630 nm is used to excite the Porfimer oligomers.
Porfimer is Haematoporphyrin Derivative (HpD) (See PDT).
Approvals and indications
It was approved in Canada in 1993 for the treatment of bladder cancer. It was approved in Japan in 1994 (for early stage lung cancer?). It was approved by the U.S. FDA in December 1995 for esophageal cancer, and in 1998, it was approved for the treatment of early non-small cell lung cancer.
In August 2003 the FDA approved its use for Barrett's esophagus.
