Evidence in cancer research is collected through various methods:
Laboratory Experiments: These are conducted in controlled environments to study cancer cells, genes, and molecules. Animal Studies: These involve studying cancer in animal models to understand its progression and test potential treatments before they are tried in humans. Clinical Trials: These are research studies that involve patients and are conducted in phases to test new treatments' safety and efficacy. Observational Studies: These include cohort and case-control studies that observe and analyze cancer outcomes in different groups of people. Meta-Analyses: These combine data from multiple studies to provide more robust conclusions about treatment effects and disease characteristics.
