Why does my pathology report not include classification of my LCIS?

Hello,

Welcome to icliniq.com.

LCIS (lobular carcinoma in situ) is not cancer in comparison to that of ductal carcinoma in situ. In LCIS, abnormal cells grow in lobules. It can be converted into invasive cancer in the future in some cases. LCIS itself is one of the classifications of a breast tumor. Treatment is not aggressive in such a case. Three therapies are available as follows. Close clinical examination and screening mammography or USG can be done regularly to rule out a malignant conversion. Chemotherapy can be given to prevent cancer like selective estrogen receptor modulator drug like Tamoxifen. If cancer risk is high like family history or BRCA mutation then breast can be removed surgically.
