Metastasis is, theoretically, when circulating cells embed in new areas. If you already have a secondary metastasis, it’s too late. This could potentially be a way to better determine if a cancerous tumor is still isolated to one location, or if it’s starting to shed cells that will eventually become detectably large and embedded metastatic secondary tumors.
