What Do You Know About The Doctor That Diagnosed Your Breast Biopsy?

If you or someone you know has felt a breast lump or had an abnormal mammogram, you know it can be a very scary situation.  The immediate fear is “I might have breast cancer.” When confronted with a breast health issue, many patients seek out a particular breast center or a breast doctor well-known for [...]

Understanding Your Breast Cancer Stage

Knowing the stage of your breast cancer helps your medical team determine how big the cancer is and if it has spread. This helps them guide your therapy and provide reliable prognostic information. In general, staging is done following your surgery, either after lumpectomy or mastectomy. It usually includes evaluation of the lymph nodes in [...]

What Your Core Needle Biopsy Diagnosis Means

In the past decade, core needle biopsy has taken over fine needle aspiration (FNA) as the main tool for diagnosing image-detected or palpable breast lesions. While this biopsy technique is just a sample, cores of breast tissue are removed vs. individual cells as in FNA and thus the pathologist has more information to make an [...]

Fibroadenomas and Phyllodes Tumors

Fibroadenoma Fibroadenoma is the most common benign tumor in the female breast. They generally occur in younger women but can be seen in post-menopausal women as well. Most of the time they present as a lump in the breast, but they can also be found incidentally on a breast radiology exam. To a pathologist, a [...]

What is a Metaplastic Carcinoma?

The term metaplastic carcinoma refers to a group of invasive carcinomas that appear different from all other types of invasive carcinoma because they have a unique appearance under the microscope, including having bone or cartilage or sometimes not looking at all like a typical invasive carcinoma. There are several types of metaplastic carcinoma including spindle [...]

If you have had a breast biopsy or breast surgery, a pathologist is the doctor who decides on your [...]

Special Types of Invasive Carcinoma

Most invasive carcinomas of the breast are invasive carcinoma NST (no special type), also called invasive ductal carcinoma. These account for approximately 65-75 % of invasive carcinomas. The remaining invasive carcinomas are referred to as “special type.” The most common among the special types is invasive lobular carcinoma which is the second most common type [...]

About Carcinoma in Situ: Understanding the Two Types

In the breast, there are two types of carcinoma in situ: ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS). In situ implies that the carcinoma cells have not yet escaped the confines of the ducts and lobules of the breast. (Once carcinoma cells leave the ducts and lobules and invade the surrounding [...]

Changes in HER2 Testing

HER2 (also called c-erbB-2) stands for human epidermal growth factor receptor-2. It is a protein on the surface of cells that can be over-expressed (too much of the protein) in approximately 20% of breast cancers. HER2 over-expression is usually associated with a worse prognosis but it also is predictive of response to certain systemic therapies. [...]
