Does seperate few nodules of tumor away from the cancer means was thru bloodstream?

Does seperate few nodules of tumor away from the cancer means was thru bloodstream?

If your tumor marker is greater than 0 but less than 40 (around 20-26) does it mean you still have cancer and chemo didn't get it all?

If your tumor marker is greater than 0 but less than 40 (around 20-26) does it mean you still have cancer and chemo didn't get it all?

No..: It depends on what tumor marker you are referring to. In most cancers, tumor markers are never 0 even in healthy individuals that never had cancer. What is more important than the number is the trend in the values. So if within the last 6 months the number are 20, 60, 130, 220, then it is reason to be concerned. Otherwise, it should be followed serially. ...Read more

I was recently diagnosed with a 5cm borderline malignant ovarian tumor. Is borderline malignant mean it's not cancer?

I was recently diagnosed with a 5cm borderline malignant ovarian tumor. Is borderline malignant mean it's not cancer?

It's cancer: However, it's unlikely to harm you. Different physicians may sugar-coat or say "barely cancer" or "not really cancer" but the bottom line is that I'm glad it's out or there's a fair chance it would have killed you. Read online about the statistics but if you were assured, "no spread", you've got 95%+ of it not killing you. ...Read more
