What are the characteristics of a malignant ovarian cyst?

Malignant ovarian tumors tend to have papillary excrescences, irregular walls, and/or thick septations. The tumor can contain echogenic material arising from mucin or protein debris. The more solid the areas are, the greater the likelihood that a tumor is present.

How long can cancer grow undetected?
