AI maps tumor cells that may seed later metastases

AI Summary

Researchers reveal that a cancerous tumor consists of diverse cell populations, some of which may later cause metastases or treatment resistance. Detecting these critical cell populations early remains highly challenging.

A cancerous tumor is not a single enemy. It is made up of many different cell populations that can behave in very different ways. Among them, even at the time of diagnosis, there may already be cells that months or years later could give rise to metastases or become resistant to treatment. The challenge is that these critical cell populations are extremely difficult to detect in time.
