Scientists may have discovered a cure for cancer. By accident.

Although it is too early to tell for certain, scientists say the newly discovered immune cell could potentially treat all cancers. 

A team of researchers at Cardiff University were looking at potential bacterial infection treatments when they accidentally made the discovery. 

The newly discovered immune cell possesses a never-before-seen  mechanism that acts like a grappling hook, latching on to most human cancers. 

This is a massive step towards developing a cure for cancer and a huge victory for science and medicine.
