Can keloid become cancerous? I have a keloid on my chest, which is red and connected together. It won't fester and has a slight itching.

The incidence of scar canceration is very low, so patients need not worry too much about it, but they should pay attention to prevention and early detection. Chronic stimulation, such as long-lasting wounds and unstable scars, is of great significance in the occurrence of scar canceration, so patients usually try to reduce the mechanical, chemical and thermal stimulation to the affected area, and it is best to wear pure cotton underwear to avoid repeated pulling, rubbing, bursting and infection.

Scar canceration has a long incubation period, and its malignant transformation almost always goes through the chronic ulcer stage of repeated ulcer and prolonged healing time. If the scar is allergic and itchy, repeated ulceration will last for a long time, and the ulcer secretion is much and smelly, and it is easy to bleed when touched. It looks like a volcano or a plant pattern, accompanied by obvious necrosis and infection. And pathological examination should be done in time (but it should be distinguished from ulcer infection).

Keloid is a kind of hard and raised scar, which occurs in patients with scar constitution. It is usually caused by minor trauma, especially in the chest and back, which can gradually expand and usually feel itchy or painful. Such patients should pay attention to avoid trauma, scratches and surgery. If you still don't understand, you can click on my name at the bottom right and I'll help you answer it.
