LCIS, an acronym (i.e., abbreviation based on the initials) for lobular carcinoma in situ, is also called lobular neoplasia. Although LCIS is not really cancer, it is included in the terms used to describe types of non-invasive breast cancers.
LCIS is characterized by a dramatic increase in the number of cells present in the milk-producing lobules of the breast, but does not spread beyond this area.
Although the LCIS itself does not turn into an invasive form of breast cancer, women with LCIS are at a higher risk of developing breast cancer in the same breast or in the opposite breast.
Because of this heightened risk, women with LCIS should have clinical breast exams 3 times a year, in addition to annual mammograms and monthly self exams. Also, women with LCIS may consider undergoing preventative forms of treatment, including hormonal therapy or surgery.
