Several challenges can undermine the credibility of cancer research:
Publication Bias: Positive results are more likely to be published than negative or inconclusive findings, leading to a skewed understanding of treatment efficacy. Conflicts of Interest: Researchers or institutions with financial interests in the study outcomes may introduce bias, intentionally or unintentionally. Data Fabrication: While rare, instances of data fabrication or manipulation can severely undermine research credibility and lead to false conclusions. Lack of Transparency: Studies that do not disclose methodologies, conflicts of interest, or funding sources are less credible.
