Types of Breast Cancer Biopsies
Your doctor may refer you to a surgeon or breast disease specialist for a biopsy. The surgeon will remove fluid or tissue from your breast in one of several ways:
- Fine-needle aspiration biopsy: Your doctor uses a thin needle to remove cells or fluid from a breast lump.
- Core biopsy: Your doctor uses a wide needle to remove a sample of breast tissue.
- Skin biopsy: If there are skin changes on your breast, your doctor may take a small sample of skin.
- Surgical biopsy: Your surgeon removes a sample of tissue.
- An incisional biopsy takes a part of the lump or abnormal area.
- An excisional biopsy takes the entire lump or abnormal area.
A pathologist will check the tissue or fluid removed from your breast for cancer cells. If cancer cells are found, the pathologist can tell what type of breast cancer it is. The most common type of breast cancer is ductal carcinoma, which begins in the cells that line the breast ducts. Lobular carcinoma is another common type; it begins in the lobules of the breast.
Testing for Hormones, HER2, and Genetic Mutations
Specific tests are performed on the tissue removed during the biopsy. It may take several weeks to get the test results, which we realize will be a stressful time for you. While it can be hard to wait patiently, be assured that going over these test results in depth will help your doctor decide which cancer treatments are likely to work best for you.

Some breast tumors have receptors for estrogen or progesterone that fuel the cancer's development. The path forward for estrogen-positive or progesterone-positive breast cancer is specific to blocking these hormones to slow the growth of the cancer.
HER2 Neu Receptors
This test shows whether the breast tissue has too much HER2/neu protein present. If it does, then a targeted therapy may be a treatment option to block that protein from producing too much, slowing the growth of the cancer.
Testing may be performed to determine if there are specific genes that have mutated to cause the breast cancer, which can be treated with specific targeted therapies. You may also qualify for testing to determine if you have an inherited genetic mutation.
