There's a reason knowledgeable people don't talk about 'curing' cancer. Cancer is what happens when cells fail (specifically, when they don't self-terminate when they should), so it can't be vaccinated against in the same way as a disease (much as you can't catch it in conventional terms). It can be treated, the success rate of which is increasing all the time, but people will always be diagnosed with cancer if they are unlucky. For that reason, even if treatment becomes 99.99% successful with little to no side effects, it will never be eliminated in the same way diseases such as smallpox or plague were.
