Scientists have found how cancer cells move around, by tracking them in the body. They found that if a protein EPHA2 is inactive, cancer cells can spread.
If the receptor protein is active, the cancer cells cannot leave the blood stream
The research, published in the Science Signaling journal, went on to look specifically at breast cancer.
According to Dr. Claus Jorgensen the next step is is find out how EPHA2 is kept active. "The tumor cells can’t leave the blood vessels - stopping breast cancer spreading and making the disease easier to treat successfully," he said.
