Eyedrops made from pig semen help kill cancer in mice: Study

Researchers have developed eyedrops using pig semen which can deliver cancer drugs to the back of eye. An experiment on mice showed the eyedrops killed cancer cells, slowed tumour growth and ultimately saved the retinas. Scientists aim to use this approach to treat retinoblastoma in children, which is typically treated using injections that can damage non-cancerous parts of the eye.
