Como uma única vacina está virando o jogo contra o câncer

Cancer is a scary illness. But one vaccine is helping a lot. It fights a virus called HPV. This virus causes most cervical cancer. The vaccine stops the virus first. So the cancer does not start. In England, the news is very good. There are far fewer cases now. Young women are not dying from it. Doctors are very happy. Now they have a new idea. The same plan can fight other cancers. One vaccine helps with skin cancer. Another helps very sick patients live longer. The work is not finished. But there is real hope. A big problem can have an answer.
