Cancer risk & early-detection questions
Cancer screening works best when established screening is matched to age and risk. New multi-cancer blood tests are promising research tools, but they do not replace proven screening programmes.
MMS plain-English explanation
Understand the concern without losing the medical meaning.
A blood test that looks for cancer signals is not the same as diagnosing cancer. A positive result needs proper follow-up, and a negative result cannot guarantee that cancer is absent.
✓Age- and sex-appropriate established screening
✓Family history and inherited-risk assessment
✓Smoking and other major risk factors
Established screening
Use recognised screening programmes according to age, sex, history and local guidance.
