Lobular Carcinoma in situ (LCIS)
LCIS is a noncancerous (benign) growth change in some of the cells in the milk glands, called lobules. Although its name implies otherwise, it is not considered a true cancer and does not require treatment. But it does mean you may have an increased risk of getting ductal breast cancer or invasive lobular carcinoma in the future.
Invasive Lobular Carcinoma
Fewer people get lobular carcinoma than ductal carcinoma. This cancer starts in the lobules and has spread outside of the lobules. It requires treatment.
