Sometimes if LCIS is found using a needle biopsy, the doctor might recommend that it be removed completely (with an excisional biopsy or some other type of breast-conserving surgery) to help make sure that LCIS was the only abnormality there.
Does LCIs turn into cancer?
Abstract. Lobular carcinoma in situ (LCIS) is not only a relative newcomer among breast lesions, but in its short span of 50 years it has gradually evolved from a rare form of breast cancer to being merely a marker of increased risk. This change has not been without controversy which persists to the present day, although there is now general ...
What if basal cell carcinoma is untreated?
What is the treatment for lobular carcinoma in situ? Your treatment depends on the kind of LCIS you have, your personal health and medical history and your personal choice.

Is melanoma in situ the most curable stage?
Nov 28, 2017 · Treatment modalities included no surgery (NS), lumpectomy alone (LA), lumpectomy with radiation treatment (LRT), mastectomy alone (MA) and mastectomy with radiation treatment (MRT). The overall survival (OS) was calculated by the Kaplan-Meier method.
What are symptoms of ductal carcinoma in situ?
Lobular Carcinoma In Situ (LCIS) is a condition where abnormal cells are found in the lobules of the breast. The atypical cells have not spread outside of the lobules into the surrounding breast tissue. LCIS is highly treatable and seldom becomes invasive cancer. However, having LCIS in one breast increases the risk of developing breast cancer in either breast.
Does lobular carcinoma in situ need to be removed?
Overview. Lobular carcinoma in situ (LCIS), also known as lobular neoplasia, is a rare condition in which abnormal cells develop in the milk glands, known as lobules, in the breast. These abnormal cells are not considered to be breast cancer and don't require any treatment beyond surgical removal.
How is carcinoma in situ treated?
The standard treatment is breast-preserving surgery (a lumpectomy) with radiation therapy, which results in successful outcomes for most patients. Cancers can be larger than expected, so about 20% of the time, patients need a re-excision lumpectomy — another surgery — to remove all of the cancer.
What stage is lobular carcinoma in situ?
Stage 0 means the cancer cells are still within the breast lobule and have not invaded deeper into the surrounding fatty breast tissue. This is called lobular carcinoma in situ (LCIS), a non-invasive breast cancer. In stage 0 cancer, the cancer has not spread to lymph nodes or distant sites.
Is lobular carcinoma in situ considered cancer?
LCIS is not considered cancer, and it typically does not spread beyond the lobule (that is, it doesn't become invasive breast cancer) if it isn't treated. But having LCIS does increase your risk of later developing an invasive breast cancer in either breast.Jan 25, 2022
How serious is carcinoma in situ?
Carcinoma in situ refers to cancer in which abnormal cells have not spread beyond where they first formed.

E-cadherin is a test that the pathologist might use to help determine if the carcinoma in situ is ductal (DCIS) or lobular (LCIS). (The cells in LCIS are usually negative for E-cadherin.) If your report does not mention E-cadherin, it means that this test was not needed to make the distinction.
What is a breast biopsy?
When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. The pathologist sends your doctor a report that gives a diagnosis for each sample taken. Information in this report will be used to help manage your care. The questions and answers that follow are meant to help you understand medical language you might find in the pathology report from a breast biopsy, such as a needle biopsy or an excision biopsy.

As long as the carcinoma cells are still ...
Can calcifications be seen on a mammogram?
They can be seen both on mammograms and under the microscope. Because certain calcifications are found in areas containing cancer, their presence on a mammogram may lead to a biopsy of the area. Then, when the biopsy is done, the pathologist looks at the tissue removed to be sure that it contains calcifications.
Is lobular carcinoma in situ a pre-cancer?
Lobular carcinoma in situ (LCIS) is a type of in-situ carcinoma of the breast.
