Data from many sources (e.g. primary care records, clinical trials, observational studies, etc) are analysed to create medical statistics. These statistics are then collected and evaluated to ultimately improve medical practice.
Medical statistics are usually collected by gathering the relevant published articles which contain them. The main problem that can arise from this is that the articles may be selected in a particular way, for example only articles favouring a particular outcome may be selected, which would bias the evaluation of the evidence. Systematic reviews are designed to reduce the chance of this, however they may not eliminate it. Meta-analyses can be conducted to combine the statistics from several sources, but meta-analyses also have their problems.

Are Colon cancer survival statistics accurate?
Whether colon cancer statistics are accurate would depend on the statistics.

No accurate statistics are available for alternative treatments, because they are generally considered ineffective by organizations that keep statistics.
