The new technique could help tackle hard-to-reach tumours
Injecting cancerous tumours with a chemical then zapping them with a flash of light can cause them to commit "cell suicide", scientists have found.
A new technique can kill the cells in under two hours, and clinical trials with laboratory mice have a 95% success rate.
The technique is called "photodynamic therapy" and has been shown to cause cancer cells to effectively self-destruct in fewer than 120 minutes.
The "cell suicide" happens because they became too acidic to survive after being injected with chemical compound nitrobenzaldehyde.
The flash of light kick-starts the chemical reaction.
