Most people who discover that they have breast cysts usually do not require any treatment or follow-up. Many cysts go away naturally.
However, if the cyst is large and causing discomfort, or does not go away on its own, your doctor may draw out the fluids using a fine needle. Once the fluid has been drained, the cyst usually disappears. You may feel some discomfort as the fluid is being drawn, and the area may feel bruised and tender for some days after. If so, painkillers such as paracetamol can be taken.
The fluid drawn from the cyst can vary in appearance, from clear to a dark colour. Usually, it is only sent to a laboratory for testing if it is blood-stained, as this may indicate breast cancer.
Cvsts can grow back or you may develop new cysts. If you think a cyst has returned or a new cyst has formed, please have it examined by a doctor.
In a minority of cases, the cyst may be cancerous, especially if there are sinister factors seen on ultrasound. In such cases, the doctor will advise you on the appropriate treatment.
