Breast cancer cells could be stopped from spreading by being turned into harmless fat cells, scientists have shown.
Cancer cells are able to adapt and spread using a certain pathway, but scientists in Switzerland have been able to exploit it in a mice study.
The combination therapy uses a diabetes drug and a cancer drug which work together to convert the cells into fat and stop them from reverting back to cancer.
It still needs to be clinically tested, but the team at the University of Basel hope the process will be quicker because both drugs are already approved by the FDA.
Breast cancer is the most common cancer in the US and UK, with around 150 people diagnosed a day in the UK, according to Cancer Research.

The team, led by biochemist Professor Gerhard Christofori, targeted the cancer cells during a process called epithelial-mesenchymal transition (EMT).
EMT is used by the body, usually associated with the development of organs and wound healing.
For example, when you cut your finger, some of the cells become 'fluid', changing into a type of stem cell which can then grow into whatever kind of cell the body needs – bone, skin or blood.
Cancer cells use EMT to alter their molecular properties and change into a different type of cell, enabling them to spread around the body.
During EMT, they are in an highly changeable state, which is when researchers see them as vulnerable to target in a 'window of opportunity'.
The researchers treated mice implanted with an aggressive form of human breast cancer.
They were given both a diabetic drug called rosiglitazone and a cancer treatment called trametinib.
The cancer cells, which had broken free from the primary site to spread, were changed into fat cells – a process called adipogenesis.
It didn't work with every cell, but in the successful cases they showed no signs of transitioning back, growing into a tumour, or spreading to surrounding tissue.
One of the authors, Professor Christofori said: 'The breast cancer cells that underwent an EMT not only differentiated into fat cells, but also completely stopped proliferating.
'As far as we can tell from long-term culture experiments, the cancer cells-turned-fat cells remain fat cells and do not revert back to breast cancer cells.
'Since we have used FDA-approved drugs to study the preclinical effect of the treatment, a clinical translation may be possible.'
In the meantime, the team are looking into the prospect of using the therapy in combination with chemotherapy.
Professor Christofori said: 'In future, this innovative therapeutic approach could be used in combination with conventional chemotherapy to suppress both primary tumour growth and the formation of deadly metastases.'

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.
Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
