In which situation is a cyst aspiration typically performed?

Cyst aspiration is typically performed to relieve pressure from cysts. A cyst is a fluid-filled sac that can develop in various tissues and can lead to discomfort or pain if it becomes too large. By aspirating the cyst, the fluid is removed, which can alleviate any pressure symptoms and provide relief to the patient.

Additionally, cyst aspiration can also aid in diagnosis when the cyst includes cellular content that can be evaluated. However, the main intent of the procedure is often therapeutic, aimed primarily at relieving symptoms associated with the cyst's size or pressure on surrounding tissues.

Other procedures and approaches are generally utilized for solid tumors, drainage of infected tissues, or diagnostic assessments that focus on lymph nodes, which do not typically involve the aspiration of cysts directly. Thus, in the context of this question, the choice that accurately describes the purpose of cyst aspiration is centered on the relief of pressure caused by the cyst itself.
