Which type of skin growth is typically non-cancerous?

A steatoma, commonly known as a sebaceous cyst, is a type of skin growth that is typically non-cancerous. It arises from the sebaceous glands and usually appears as a small, painless lump under the skin. Steatomas occur when the gland's duct becomes blocked, leading to an accumulation of sebum (the oily substance produced by sebaceous glands).

Though they can vary in size and may occasionally become inflamed or infected, steatomata are generally benign, meaning they do not have the potential to develop into cancer. This makes them different from other skin growths that could be malignant or indicative of a more serious condition. Understanding the nature of these skin growths helps in identifying and managing skin health appropriately.

In contrast, tumors can be either benign or malignant, cysts can also occur as benign or harmful growths depending on their characteristics, and nodules can represent various conditions, including those that may be cancerous. Each of these growth types has distinct characteristics and implications for health, which is why recognizing the benign nature of a steatoma is important in esthetics and skincare practice.
