Lobular carcinoma in situ (LCIS) is an area (or areas) of abnormal cell growth that increases a person’s risk of developing invasive breast. Lobular carcinoma in situ (LCIS) is an incidental microscopic finding with characteristic cellular morphology and multifocal tissue patterns. The condition is a. Lobular carcinoma in situ (LCIS) represents the next step up from atypical lobular hyperplasia (ALH) along the malignant spectrum of lobular breast carcinoma.

Marker for breast cancer risk”. LCIS usually doesn’t show up on mammograms. Because LCIS is linked to an increased risk of cancer in both breasts, some women with LCIS choose to have a bilateral simple mastectomy removal of both breasts but not nearby lymph nodes to lower this risk. Routine carciinoma showing suspicious radiologic findings warrant a core needle biopsy in the abnormal area seen radiologically, and may or may not show lobular neoplasia histologically.

From Wikipedia, the free encyclopedia. This is because lobular carcinoma is known to spread lobulillag other parts of the body such as bone and lung tissue.

Researchers and physicians currently treat the diagnosis as a precursor lesion and risk factor for subsequent development of breast cancer. When lobular carcinoma becomes a serious illness, it is usually because carinoma can not determine or remove the full extent of the malignancy. The management of lobular carcinoma in situ LCIS.

LCIS is usually incidentally-identified histologically in breast tissue biopsied for other reasons. This usually includes a yearly mammogram and a breast exam. While older studies have shown that the increased risk is equal for both breasts, a more recent study suggests that the ipsilateral same side breast may be at greater risk. But having LCIS increases your risk of breast cancer and makes it more likely that you may develop invasive breast cancer.


In terms of the pathological evaluation of infiltrating lobular carcinoma, one looks for: A little clarification of language and terminology is necessary here.

When should I see a doctor? What we could do now: The abnormal cells remain in the lobule and do not extend into, or invade, nearby breast tissue.

Diseases of the breast. Monomorphic cells have no specific orientation to basement membrane.

You could also consider participating in a clinical trial as well, to explore any emerging, new therapy for preventing breast cancer. Support Radiopaedia and see fewer ads. What are the risk factors?

Lobular Carcinoma in situ (LCIS)

Lobular carcinoma in situ LCIS is an incidental microscopic finding with characteristic cellular morphology and multifocal tissue patterns. One would assume that the higher rates carcinoka local recurrence in invasive lobular carcinoma would also reflect higher rates of lymph node and regional metastasis, but this is not the case.

Ductal carcinoma in situ DCIS: Lobular carcinoma in situ is not a precursor of breast cancer, but rather a sure indication of the presence of breast cancer.

Breast cancer lesions may originate anywhere in carcinomz breast, but they most often occur either in the breast ducts, or the lobules.
