Scientists have found a way to get treatment for a rare type of cancer into the back of the eye without damaging the nearby structures: by using a particle derived from pig semen.
The approach, which was tested in mice, targets a cancer called retinoblastoma and takes advantage of sperm's ability to penetrate barriers. If the new technique can be demonstrated as safe and effective in people, it could help retinoblastoma patients, who are mostly young children, receive chemotherapy without having to face painful and potentially eye-damaging injections.
