I think Felix means that if you do nothing with malignant neoplasm, you can only survive a few years at best. However, if you get best treatment, the thing may be different. And it also depends on the size, type and the stage of your tumor. I got malignant neoplasm in my right breast on May 2019. It's stage 2. The tumor is smaller than 2cm. And the doctor said it didn't mean I should give up hopes. In fact the survival rate in this stage is still as high as about 93%. I took chemo and radiation therapies. And now I've almost recovered from this, though still need to go back to do some tests. So don't give up hopes. You still have a great chance to survive if it's not metastatic.
