The exact cause of pyogenic granuloma is not fully clear, but it seems to be an exaggerated healing response of blood vessels, often after minor injury, irritation, or burns. Hormonal changes, some medicines, and pregnancy can also trigger or promote these growths.
Pyogenic granuloma itself is benign and does not turn into cancer, but it can bleed heavily or get infected if irritated. The main medical risk is confusing it with a skin cancer that can look similar, which is why a proper diagnosis is important.
Pyogenic granulomas are usually treated by removing them, most often with surgical excision, laser, cautery, or freezing, followed by histology to confirm the diagnosis. Because they are very vascular, careful control of bleeding during and after the procedure is important.
