Red Flags in History
Warning signs that demand attention

Certain features in a patient's history should immediately raise concern and prompt further investigation or referral.
These include:
- Rapid changes in a lesion
- Bleeding or ulceration
- Persistent or non-healing areas
- Lack of a clear cause
Such features may indicate a more serious underlying condition, including malignancy. In these situations, aesthetic treatment should not be performed until a proper medical evaluation has been completed.
Recognising red flags early is essential for patient safety and is a key responsibility of any practitioner working with the skin.
Clinical Takeaway
When you encounter a red flag, document your findings thoroughly and refer promptly. Never attempt to diagnose or treat suspicious lesions.
