| cyst | A cyst is simply a fluid filled structure. A "complex" cyst has internal structures or septations. A cyst with no internal structures (simple cyst) is extremely unlikely to be cancerous at any age. A complex cyst, especially if it contains many solid areas and is larger has a higher chance of being malignant. The chances of malignancy in a complex cyst are also related to age. If the age is greater than 50 and there are more than a few septations, the chances of malignancy approaches 50%. However, it is extremely important that the particulars of your situation and the actual ultrasound films are reviewed by an expert before treatment decision-making. |
