South Wales could become the home of the UK's first proton beam therapy treatment centre which helps treat the most complex and hard-to-reach cancers.
The centre, due to open at Celtic Springs Business Park, Newport, by 2016, will see Wales leading the way in the treatment.
There are currently only 40 therapy centres around the world.
The potential centre has been described as a 'significant inward investment to Wales' that will 'save lives on Welsh soil'.
Proton beam therapy provides a highly targeted radio therapy and has been described as a so-called 'miracle' treatment. It's estimated that by 2017 the NHS demand for proton beam therapy will reach 1,500 patients.
Currently people have to go abroad for the treatment, including two-year-old Freya Bevan, from Swansea, who suffers with a rare brain tumour.
Proton therapy also helped saved the life of Ashya King who was recently declared cancer-free after proton beam therapy in Prague.
This is an exciting and important development of the UK provision of cancer treatment. As things stand, patients who can benefit from this treatment have to go abroad, often at a great expense to the NHS.
The creation of these centres will go a long way to ensuring the very best of treatment is available in the UK.

A Welsh cancer charity is warning people to take extra care as they prepare for a Sunday in the sun.
Recent figures from Tenovus show malignant melanoma is now one of the most common cancers in people aged 15-35 and cases have almost quadrupled in the last 30 years.
The charity is touring beaches, schools and parks in an ice cream van to raise awareness of the risks of sitting out in the sun.
A new way of measuring waiting times for cancer treatment is being trialled across Wales in a bid to improve patient care.
Doctors say the current targets - where patients need to be treated within 62 or 31 days, depending on how they are referred - is too 'blunt' an instrument.
But the Conservatives say the Welsh Government is simply scrapping targets it has failed to meet since 2008.
Health advisors say the drug would have cost more than £90,000 per patient, but some have likened the decision to 'putting a price on life'.Read the full story ›
Every week here in Wales 50 people are diagnosed with breast cancer alone, making it the most common type of cancer for women. The so-called celeb effect has made us more aware than ever before.
