The cystic nature of a breast lump can be confirmed by ultrasound examination, aspiration (removal of contents with needle), or mammogram. Ultrasound can also show if the cyst contains solid nodules, a sign that the lesion may be pre-cancerous or cancerous.
The diagnostic process for a breast lump involves verifying its fluid-filled characteristics through methods like ultrasound imaging, fine-needle biopsy, or X-ray mammography. Moreover, ultrasound can detect the presence of solid growths within the cyst, which may signal that the lesion is at risk of becoming precancerous or cancerous.
