pre-malignant neoplasm
Let an agent explain pre-malignant neoplasms in general terms, relay grading, examples, screening and management approaches from pathology and cancer prevention sources, describe the named lesions and flag the contradictory registry parent, and distinguish precancers from cancer in situ as defined by staging systems, invasive cancer, benign tumours and risk factors, without diagnosing or interpreting individual results.

What it is Filled
An abnormal growth of cells that is not cancer but has an increased risk of becoming cancer, also called a precancerous lesion, often graded by dysplasia or intraepithelial neoplasia, with examples the registry aliases name such as squamous intraepithelial lesions of the cervix, prostatic intraepithelial neoplasia, glandular and transitional cell intraepithelial neoplasms, conjunctival intraepithelial neoplasia and precancerous lesions of the eyelid skin; others include actinic keratosis, Barrett oesophagus and colorectal adenomas. The registry parent neoplastic malignancy contradicts the concept, since these lesions are by definition not malignant. Screening programmes detect many precancers so they can be monitored or treated, and people should follow screening guidance and discuss results with clinicians.
Why it exists Filled
Let an agent explain pre-malignant neoplasms in general terms, relay grading, examples, screening and management approaches from pathology and cancer prevention sources, describe the named lesions and flag the contradictory registry parent, and distinguish precancers from cancer in situ as defined by staging systems, invasive cancer, benign tumours and risk factors, without diagnosing or interpreting individual results.
Distinguishing features Filled
- Increased cancer risk
- Graded dysplasia
- Found by screening
- Often treatable
What robots and AI may and may not do Filled
Must not
- Tell a person their lesion is harmless or certainly cancer.
- Advise skipping, delaying or replacing recommended follow-up or treatment.
- Recommend unproven remedies as a way to reverse a precancerous lesion.
- Disclose a person's screening or biopsy results without consent.
Only with a human decision
- Any decision to treat, remove or watch a particular lesion.
- Delivering an abnormal result to a patient.
May
- Explain in general terms what a precancerous lesion is and why follow-up matters.
- Remind people with abnormal screening results to keep their follow-up appointments.
- Summarise screening guidance from named health authorities with dates.
Moral aspects Filled
- Missed follow-up lets preventable cancers develop, while overtreatment causes avoidable harm.
- Abnormal results cause anxiety, and some lesions carry stigma, such as those linked to infections.
Who is affected
- Patients with abnormal results
- Their families
- Screening programmes
