Invasive Mammary Carcinoma (IMC)

Invasive mammary carcinoma, also known as infiltrating mammary carcinoma, is a mixture of invasive ductal and lobular carcinomas; meaning the cancer grows at the junction of the duct and the lobule.

How is invasive mammary carcinoma diagnosed?

Same Day Results

At the Johns Hopkins Breast Center, our breast specialists understand how quickly patients want results from a biopsy or scan if there is a suspicion of breast cancer. We follow strict guidelines for biopsies and pathology reports. Most of our patients will receive diagnosis immediately following their biopsy procedure, and a pathology confirmation within 24 hours.

What is the treatment for invasive mammary carcinoma?

Invasive mammary carcinoma is treated with a lumpectomy or mastectomy, depending on the size and location of the tumor. Your oncology team also may recommend chemotherapy and/or radiation, hormonal therapy or biologic targeted therapy. Sometimes an MRI is done to help determine the diameter of the tumor. Lobular cancer cells grow differently and a traditional mammogram may not reveal its large size.

What is the prognosis for invasive mammary carcinoma?

Prognosis depends on individual markers, including the staging of your tumor. Your physician will discuss your prognosis with you.
