Fight against cancer

In the past, we only had a radiation treatment for cancer. This treatment is based on X-rays. It's not very good, speacially for children, because it can hurt other parts of the body.

 

Seventy years ago, Robert Wilson had the idea of using the proton therapy. Now this charged-particle therapy is very famous, because it mainly damages the tumor. It's used in Unites States in fourteen centers and in other countries such as Germany, Italy, China or Japan.
