Sure. Right now, at stage 0 or stage 1, if it's found that early, as it often is in screening, you have about a 99% survival rate. By the time it gets to stage 4, we're talking about a 31% survival rate. Although that number is getting better with research and the medicine that we have now, and people with metastatic breast cancer are living longer, they cannot be cured. If you are at an early stage, you can be cured with the medicine that we have today.
That's the difference between going in, getting screened and finding out you're at stages 0, 1 or 2, versus it being too late when you're at stage 3 and it's in the lymph nodes, or you're at stage 4, when it's in your liver, bones or lungs. The timing is the difference.
