Women who are diagnosed with lobular carcinoma in situ (LCIS) have a 10-20 percent chance of developing invasive breast cancer some time in their life. The condition is often found when a biopsy is conducted of suspicious tissue, or after having an abnormal mammogram. Our bodies are constantly growing and developing new cells; when this process goes wrong, the buildup of extra cells can turn into a mass of tissue called a growth, tumor, or lump. Breast cancer is caused by this over-production of cells that occurs in the breast tissue. Many growths in the breast can be benign (not cancer), while some may be malignant (cancer).
LCIS is not breast cancer (Stage 0), but a marker for possible future breast cancer. It occurs when abnormal tissue grows and stays in the lobules or milk glands located at the end of the breast ducts. Most women with LCIS exhibit no symptoms of the condition, but some may experience a lump in the breast. Women in their 40s or 50s typically are more commonly diagnosed with LCIS, but older women may also have it.
When you visit your gynecologist, he/she will often perform a breast examination, however, you should also be checking periodically for lumps or other abnormalities in your breasts. When pregnant or during your period, breast tissue can become “lumpy” because of hormones, so suspected growths found during those times (particularly ones that remain after your period or pregnancy) may not be cause for alarm, but should still be checked by your doctor.
If you suspect you may have something wrong with your breasts, it is important to discuss it with your doctor to assure early detection and treatment. Some questions you may want to ask include:
•Careful observation – frequent breast self-exams, clinical breast exams screening mammograms every year, and other imaging techniques to catch any cancer early.
•Medication (chemoprevention) – selective estrogen receptor modulator (SERM) drugs are used to reduce the risk of developing invasive breast cancer (Tamoxifen, or Raloxifene).
•Preventative surgery – prophylactic mastectomy to prevent the risk of developing breast cancer.
•Clinical trials also may be a choice to help explore emerging therapy for preventing breast cancer (ask your doctor what’s available that may be right for you).
