If we just look at the case of breast cancer for example, we find that those who are diagnosed and treated at stage one have a five-year survival rate of nearly 100 percent -- odds that decrease to just 22 percent if treated at stage four.
Se analisarmos, por exemplo, o câncer de mama, vemos que as pessoas diagnosticadas e tratadas no estágio 1 têm quase 100% de chance de viver mais cinco anos. Essa taxa cai para apenas 22% se o paciente for tratado no estágio 4.
