LCIS is not considered to be cancer, and it typically does not spread beyond the lobule (become invasive breast cancer) if it isn’t treated. But having LCIS does increase your risk of developing an invasive breast cancer in either breast later on, so close follow-up is important.
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.
What does in situ cancer mean?
Carcinoma in situ (CIS) is a group of abnormal cells that are found only in the place where they first formed in the body (see left panel). These abnormal cells may become cancer and spread to nearby normal tissue (see right panel).
How often does LCIS turn into cancer?
The risk of breast cancer in women diagnosed with LCIS is thought to be approximately 20 percent. Put another way, for every 100 women diagnosed with LCIS , 20 will be diagnosed with breast cancer and 80 won’t be diagnosed with breast cancer.
Does Lobulated mean cancer?
Invasive means that the cancer has “invaded” or spread to the surrounding breast tissues. Lobular means that the cancer began in the milk-producing lobules, which empty out into the ducts that carry milk to the nipple.
Is lobular carcinoma in situ benign?
LCIS and another type of breast change (atypical lobular hyperplasia, or ALH) are types of lobular neoplasia. These are benign (non-cancerous) conditions, but they both increase your risk of breast cancer.
Should I have a mastectomy for LCIS?
Another option for treating LCIS is preventive (prophylactic) mastectomy. This surgery removes both breasts — not just the breast affected with LCIS — to reduce your risk of developing invasive breast cancer.
How serious is carcinoma in situ?
Carcinoma in situ refers to cancer in which abnormal cells have not spread beyond where they first formed. The words “in situ” mean “in its original place.” These in situ cells are not malignant, or cancerous. However, they can sometime become cancerous and spread to other nearby locations.
Is in situ the same as benign?
In addition to benign tumors, there are in situ tumors and invasive tumors. In situ tumors do not invade the basement membrane, whereas invasive tumors do invade the basement membrane.
What is the treatment for carcinoma in situ?
Treatment of DCIS has a high likelihood of success, in most instances removing the tumor and preventing any recurrence. In most people, treatment options for DCIS include: Breast-conserving surgery (lumpectomy) and radiation therapy. Breast-removing surgery (mastectomy)
What is a lobular carcinoma in situ?
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 long does it take for LCIS to become invasive?
If a woman with LCIS develops an invasive breast cancer, it doesn’t typically happen within a few years. Rather, it is more likely to happen over the long-term — in 10, 15, or 20 years or even beyond that.
Can LCIS be removed?
The best way to treat LCIS found on a needle biopsy is not clear. In some cases where LCIS is found on needle biopsy, the doctor might recommend that it be removed completely (with an excisional biopsy or some other type of breast-conserving surgery).
Why are lobular cancers sneaky?
Instead of clustering together, lobular cells spread out single file like tree branches or spider webs or mesh, which explains why surgeons and oncologists often refer to it as “sneaky” or “insidious.” Because the cells don’t stick together well, there’s often no lump, making it harder for women to find during self- …
What does lobulated Mass mean?
US image shows the mass (arrows), which was prospectively described as “lobulated,” a term that is not a BI-RADS US descriptor. The lesion has less than three undulations and therefore can be described as having an oval shape.
What is the meaning of lobulated?
: made up of, provided with, or divided into lobules a lobulated tumor.
