When a lump, or a bump is discovered in superficial areas of the body such as the breast and neck, a test known as Fine Needle Aspiration Cytology (FNAC) is recommended to determine whether the lump is cancer. This procedure is also used to test for thyroid, salivary glands and lymph nodes illnesses.

Fine needle aspiration is only used for lumps that can be felt (palpable masses). Although core needle biopsy is usually the first choice for palpable masses, fine needle aspiration is sometimes done as a quick way to sample a breast lump felt during a clinical breast exam.
