Following radiation treatment, tumors can recur in the same spot as before. But retreating these tumors with conventional photon therapy can expose nearby organs to yet more radiation—which is a big problem, since bodily organs can only tolerate so much radiation over their lifetime.
In contrast, proton therapy deposits very little radiation into nearby organs. So it’s ideal for treating a tumor that has recurred.
The clinical staff at the New York Proton Center includes Dr. Charles B. Simone, one of the world’s foremost experts in treating cancer recurrence.
