Technion team discovers new process for attacking cancer cells

When treating cancer, researchers are always searching for ways to remove cancer cells while minimizing damage to the rest of the body. One possible approach is to find processes unique to cancer cells, and which would allow specific targeting. If such a process can be disrupted, only those cells would be affected.
