Clinical tools
Free UK-guideline-aligned calculators for everyday skin cancer practice. Each output cites the underlying guideline. Pure browser-side — no data leaves your device. Educational use, not a medical device.
Tools support guideline lookup and documentation. They do not replace MDT decision-making, histopathology review or clinician judgement. Local Cancer Alliance and trust pathways take precedence; urgent clinical concern overrides tool output.
