If the lump is a solid growth, then the tip of the needle is passed back and forth multiple times obtain cells for further analysis.

Is fine-needle aspiration uncomfortable?
You will probably feel only minor discomfort since the skin over the lump tissue can be numbed.

What are the possible benefits of undergoing this procedure?
It can reduce the need for more extensive surgical procedures. Draining a lump (cyst) is simple and can reduce discomfort and make the lump go away. Solid lumps can be checked for cancer.

Yes, you should do what your doctor recommends. Another physical exam or mammogram within the next year may be required.
