British scientists have described trial results for a new breast cancer treatment as "staggering".
The treatment has dramatically reduced tumours, and in some cases removed the need for chemotherapy.

The study focused on patients with the HER2 positive strain of breast cancer, and some women saw their tumours dramatically shrink or disappear in just 11 days.
