But what about the part that goes into the tumor?

And look at how the tumor sizes plummeted in between.

In cancer, cells rapidly divide and lead to uncontrolled tumor growth.

And then the second group received only Tumor Treating Field therapy.

They're attached to the skin in the area of the tumor.

And now, boom, the tumor labels itself and it gets fluorescent.

That cloudy white mass that you see is the recurrence of the tumor.

In the lab, we've observed tremendous synergies between chemotherapy and Tumor Treating Fields.
