Not all patients with a breast lump will need diagnostic tests like ultrasound or mammography. Some may just need a needle aspiration like what happen in the abovementioned patient. The result is dramatic if the mass turns out to be a macrocyst, which are relatively common. Dramatic in the sense of instant definitive diagnosis and instant resolution or disappearance of the mass. In about 15 minutes, there is a definitive diagnosis of a macrocyst and there is resolution or disappearance of the mass. No further treatment is needed. Just monitoring and observation.
