Is LCIS a premalignant?

Initially LCIS was considered a premalignant lesion, but it is now a marker of increased risk. The number of women diagnosed with LCIS has increased in recent years most likely owing to more rigorous breast cancer screening.

Can atypical lobular hyperplasia turn into cancer?

Atypical hyperplasia isn’t cancer, but it increases the risk of breast cancer. Over the course of your lifetime, if the atypical hyperplasia cells accumulate in the milk ducts or lobules and become more abnormal, this can transition into noninvasive breast cancer (carcinoma in situ) or invasive breast cancer.

What is the difference between LCIS and DCIS?

Lobular carcinoma in situ (LCIS) is a type of in-situ carcinoma of the breast. While DCIS is considered a pre-cancer, it is unclear whether LCIS is definitely a pre-cancer or if it is just a general risk factor for developing breast cancer.

Should LCIS be removed?

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.

Is LCIS serious?

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.

Is surgery necessary for atypical lobular hyperplasia?

Atypical hyperplasia is generally treated with surgery to remove the abnormal cells and to make sure no in situ or invasive cancer also is present in the area. Doctors often recommend more-intensive screening for breast cancer and medications to reduce your breast cancer risk.

Should atypical lobular hyperplasia be removed?

Most types of usual hyperplasia do not need to be treated. But if atypical hyperplasia (ADH or ALH) is found on a needle biopsy, more breast tissue around it might be removed with surgery to be sure that there is nothing more serious nearby, such as cancer.

Can DCIS be Spiculated?

Spiculated Masses Cancers appear spiculated because of direct invasion into adjacent tissue or because of a desmoplastic reaction in the surrounding breast parenchyma. This pattern can be seen in infiltrating ductal or lobular carcinomas. It can also be seen in DCIS, although that is unusual.

What happens if DCIS is left untreated?

The cells in DCIS are cancer cells. If left untreated, they may spread out of the milk duct into the breast tissue. If this happens, DCIS has become invasive (or infiltrating) cancer, which in turn can spread to lymph nodes or to other parts of the body.

What is lobular carcinoma cancer?

Lobular carcinoma. Lobular carcinoma is a form of tumor which primarily affects the lobules of a gland. It is sometimes considered equivalent to “terminal duct carcinoma”. If not otherwise specified, it generally refers to breast cancer.

What is lobular cancer?

Lobular breast cancer, also called invasive lobular carcinoma (ILC), occurs in the breast lobes or lobules. Lobules are the areas of the breast that produce milk. ILC is the second most common type of breast cancer.

What is lobular hyperplasia?

Hyperplasia of the Breast ( Ductal or Lobular) Hyperplasia is also known as epithelial hyperplasia or proliferative breast disease. It’s an overgrowth of the cells that line the ducts or the milk glands (lobules) inside the breast.
