What is the difference between “prevention” and “early detection” of cancer?

So-called “primary” prevention is based on healthy lifestyle behaviours (proper diet, physical activity, avoidance of cigarette smoking) that, according to scientific studies, protect against the onset of cancer. Early detection, on the other hand, consists of detecting malignant tumours as soon as possible through specific tests. Those recommended by the National Health Service are, for example, mammography for breast cancer, Pap test for cervical cancer and occult blood screening and colonoscopy for colorectal cancer. Whole-Body Diffusion does not replace these tests, but complements them, because it allows you to examine all the other organs not assessed by “official” screens, and to identify even very small tumours (3-4 millimetres in diameter).
