SCIENTISTS have created a “breast cancer diagnosis pill”.
Researchers have developed a tablet that lights up cancerous tumours in a mouse’s breast tissue under near-infrared light.
Current screening methods often identify lumps but cannot always pinpoint which ones are cancerous.
In a bid to resolve this uncertainty, researchers from the University of Michigan in the United States created a pill so that only cancerous tumours light up.
The oral tablet contains an imaging agent that selectively binds to cancer cells or blood vessels that are unique to tumours, scientists said.
Once the agent has bound to the cancerous cells, the dye fluoresces under near-infrared light, the researchers added.
When testing the imaging technique in mice, the research team found that fluorescent tumours can be detected 1cm to 2cm deep.
They found that the imaging agent binds specifically to cancer cells with “little” background noise in the image.
The team now plan to formulate the pill for humans. If successful, the new technique could benefit women with “dense” breast tissue whose mammograms are typically more difficult to read, they said.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
