Proton Beam Therapy group to raise £20m

A company whose focus on a specialised form of cancer treatment sprang to prominence last year during the case of five-year-old Ashya King will disclose today that it is in talks to raise tens of millions of pounds from investors. Sky News understands that Advanced Oncotherapy, which is listed on London’s junior AIM stock market, will issue a statement in the wake of a recent surge in its share price.
