Is LCIS considered breast cancer? Lobular carcinoma in situ (LCIS) is an uncommon condition in which abnormal cells form in the milk glands (lobules) in the breast. LCIS isn’t cancer. But being diagnosed with LCIS indicates that you have an increased risk of developing breast cancer.
What is the best treatment for LCIS? Surgery. Surgery may be recommended in certain situations. For instance, surgery is often recommended for a specific type of LCIS called pleomorphic lobular carcinoma in situ (PLCIS). This type of LCIS is thought to carry a greater risk of breast cancer than is the more common classical type.
What is the survival rate of LCIS? Highlights. The incidence of LCIS increased, while surgical treatment decreased over time. 10- and 20-year relative survival rates exceeded 90 %, irrespective of surgery. The risk of breast cancer was highest after no surgery, lowest after mastectomy.
Which is worse LCIS or DCIS? This is in contrast to LCIS which has risk for the development of invasive breast cancer in either breast over time. In summary, LCIS is considered a risk factor for invasive cancer while DCIS is considered a precursor to invasive cancer.
