Scientists have developed tumour paint which could help the surgeons remove cancer more accurately and so help prevent the disease returning. This paint developed from a molecule called chemotoxin, which comes from scorpions, lights up cancer cells but not normal cells, so it could show surgeons exactly where tumours are. This tumour paint makes sure they do not hurt healthy tissues or leave cancerous cells behind during surgery, which could mean the tumours return. The paint molecule emits light near the infra red spectrum, and this illumination helps surgeons identify cancerous cells. This would be helpful because surgeons presently have to depend on colour, texture and blood supply to tell which cells are cancerous, and these features can be subtle.

Acccording to experts the tumour paint will fundamentally improve cancer therapy.
