Mets is simply short for metastasis, the development of secondary cancers at some distance from the primary source. As far as I know, this is different from a new, totally unrelated cancer occurring after the first, which of course can also happen. Some people already have metastasis when first diagnosed, unfortunately. This video is about the percentage of those diagnosed with a primary cancer, but whose cancer metastasises at a later date (sooner or later). Beyond the recommended treatment and as healthy a lifestyle as possible, I don't know how metastasis can be prevented and assume that if there are any sure fire precautions we would know! But I also don't know if I will be in a car accident next month, or if an embolism is forming! Like @melclarity, I will do everything I am asked and feel is sensible, but I still have a life to live. And as we know, from the many people on this site, there can be a life after a mets diagnosis too.
