What does a fungating tumor typically invade?

  1. Internal organs

  2. Surface tissues

  3. Bone structures

  4. Nerves only

The correct answer is: Surface tissues

A fungating tumor typically invades surface tissues, which is a hallmark characteristic of this type of tumor. Unlike other types of tumors that may grow inward or deeper into internal structures, fungating tumors are known for their outward growth, often projecting above the skin surface. This can create irregular, fungiform shapes and often results in ulceration or necrosis of the nearby tissues. Fungating tumors are often associated with advanced cancers and can lead to significant complications, including infection or impaired wound healing. Their invasive nature primarily affects the epidermal and dermal layers of the skin rather than internal organs or deeper structures, which is why surface tissues is the correct answer.
