What should you know about keratoacanthoma stages?

A lesion may start as a firm, skin-coloured or red bump. It can enlarge and develop a central build-up of hard keratin, producing a volcano-like or cratered appearance. Some lesions later flatten, crust, or appear to heal, but that pattern does not prove that the growth is harmless. Squamous cell carcinoma can have overlapping features, and sun exposure is a relevant background factor; see Sun-Damaged Skin.

Do not track a suspicious growth for weeks without arranging care, and do not pick off its centre. Photographing it beside a ruler can help show change to the clinician, while a short written timeline records growth, pain, crusting, or bleeding. A dermatologist may recommend sampling or removal. Curettage And Cautery and Surgical Excision are possible approaches, selected according to the lesion and its position.

Arrange prompt assessment when a bump grows noticeably, forms a keratin plug, bleeds, becomes painful, or changes after seeming to settle. Seek earlier care for a lesion on the eyelid, nose, lip, ear, or hand, or when redness spreads beyond the growth. Persistent bleeding, marked tenderness, or signs of infection warrant timely medical attention rather than home treatment.

Ask which features concern you, whether a biopsy is needed, whether removal is recommended now, and how the area will be monitored after treatment.
