Blood test to detect colorectal and breast cancer early

Researchers are studying whether a protein called FGF19 found in blood can be used as a simple test to detect colorectal cancer and breast cancer. This research aims to develop a blood-based screening tool that could catch cancer earlier and be easier and more convenient than current screening methods like colonoscopies and mammograms.

Many people avoid standard cancer screening tests because they are uncomfortable or inconvenient, which means cancers are often found at later stages when they are harder to treat. This study exists to create an easier alternative — a simple blood test — that could help more people get screened and catch cancer earlier, ultimately saving lives.
