In a discovery that feels almost too good to be true, scientists at KAIST have uncovered a way to reprogram cancer cells—transforming them back into healthy tissue. Instead of killing cancer, this breakthrough flips a “genetic switch” that resets the cell’s identity. No chemo. No radiation. Just cellular reversion. It’s not science fiction—it’s a bold new direction in regenerative medicine that could revolutionize how we treat cancer and understand cellular memory. If further validated, this could change the future of healthcare as dramatically as CRISPR or stem cell therapy once did.
