Ever heard of circular RNAs, or circRNAs? They're about as tiny as DNA, and they're making a big splash in cancer research. Scientists are diving deep into how these little guys might help fight cancers like colorectal, gastric, liver, and lung.

Researchers have been closely looking at these circRNAs, especially because they might be super helpful in detecting cancer early, and even in creating new treatments. There are tons of different circRNAs, with over 500 identified so far in these four main cancer types. For example, in colorectal cancer, they've found 124, and in gastric cancer, it's a whopping 177!

These circRNAs do interesting things. They can mess with gene expression, either by teaming up with microRNAs or by snagging onto RNA-binding proteins. Some circRNAs can make cancer worse, but others can actually stop cancer from growing.

You might be wondering, why not just use these in medicine already? Well, it's more complicated than that. Scientists are trying to figure out how to target these circRNAs just right. They want to stop the bad ones and boost the good ones, but it's a tricky task.

Future looks promising, though. With more research, circRNAs could be super useful for diagnosing and treating cancer. It's all about finding the right way to use them.
