Most cysts are actually benign. Malignant cysts refer to cysts that harbour cancer or those with a potential to develop into cancer.
In determining whether or not they are malignant, the cysts are monitored for changes in size and consistency with regular ultrasounds. In some cases, you might also need to get an MRI.
The surgeon would choose the necessary treatment based on symptoms such as:
- Pain
- Enlargement of the cyst size
- Presence of solid tissue within the cyst
Treatment does not necesarry mean removal. Depending on your condition, doctors might also recommend aspiration of the cyst fluid for testing.
