What procedure can be utilized for both diagnosis and treatment of breast cysts?

Fine needle aspiration is a procedure that involves using a thin, hollow needle to extract fluid from a cyst in the breast. This technique serves dual purposes: it can confirm the diagnosis of a breast cyst by evaluating the obtained fluid for characteristics consistent with a simple cyst or other abnormalities, and it can also provide immediate therapeutic relief by allowing the cyst to be drained if it is symptomatic or causing discomfort.

The ability to both diagnose and treat with a single procedure makes fine needle aspiration particularly beneficial in clinical practice, as it can alleviate patient anxiety and discomfort without the need for more invasive surgery if the cyst is benign.

In contrast, surgical biopsy is primarily a diagnostic tool that removes a larger tissue sample for examination, but it does not address the cyst directly during the same procedure. Mammography is an imaging technique used for screening or evaluating breast tissue but does not provide a method for fluid collection or treatment. Ultrasound is primarily utilized for imaging and guiding procedures but does not directly treat the cyst itself.
