Cancer has the brutal capacity of remote metastasis which usually kills the patient. Without remote metastasis, it won't fatally harm the patient in most cases. Surgery could be curative to them.
Any medication or therapy to suppress or eradicate remote metastasis has been desired. This news might be a breakthrough for metastasis suppression. Atrial natriuretic peptide;ANP, an antihypertensive hormone produced at heart, seems to be a hopeful medication for this purpose. There are a few reports that ANP has anti tumor activity in animal model.
I have a friend who suffers from breast cancer and is waiting for curative surgery after chemo protocol. There must be millions of people in the same situation. I really hope this will promise them as a powerful medication for complete remission.
