Lobular carcinoma in situ (inside) is classified as a high-risk condition. It originates in the milk-producing lobes and is rarely thought to develop into breast cancer, however, a history of lobular carcinoma in situ may put you at a higher risk of developing breast cancer in the future.
Women with a diagnosis of lobular carcinoma in situ are referred to the High-Risk Breast Cancer Program.
Invasive lobular carcinoma is characterized when the mutated cells spread from the lobules into the breast tissue.
In lobular carcinoma, lumps are uncommon and may be difficult to detect by breast exam or mammogram. You may notice thickening or fullness in the breast instead.
Lobular carcinoma is more likely than other types of breast cancer to occur in both breasts.
Anybody can develop lobular carcinoma, but certain factors may increase your risk, including:
Talk to your doctor if you notice any of the following symptoms:
Experts at the Magee-Womens Breast Cancer Program use a variety of tests and procedures to diagnose and screen for breast cancer, including:
If you're diagnosed with lobular carcinoma, treatment will depend on your general health and the results of your tests.
Your doctors and other specialists at the Magee-Womens Breast Cancer Program will work with you to consider your options and determine a course of action.
In many cases, we may also recommend additional therapies before (neo adjuvant) or after (adjuvant) surgery to control an aggressive cancer or to reduce the risk of recurrence.
Procedures and treatments for breast cancer may include:
|The surgical removal of part of the breast with a cancerous tumor (lumpectomy), breast tissue, or the entire breast. In some cases, lymph nodes are also removed. In rare cases, some of the chest muscles are removed as well.
|Sentinel lymph node biopsy
|A minimally invasive procedure to remove lymph node tissue in the armpit to check if existing breast cancer is spreading (metastasizing). Women diagnosed with an invasive breast cancer typically undergo a sentinel lymph node biopsy.
|Axillary lymph node dissection
|Surgery to remove all or a group of lymph nodes in the underarm (axilla), if your sentinel lymph node biopsy is positive for cancer.
|Additional Breast Cancer Therapies
|The administration of drugs to destroy the growth abilities of cancer cells. It is sometimes used with radiation therapy.
|The use of beams of high-energy waves of ion particles to destroy the growth abilities of cancer cells. External radiation therapy directs rays at the tumor from outside a person's body.
|The use of drugs that stop the production of certain hormones that the cancer needs to grow.
