Ligaments support the breast. They run from the skin
through the breast and attach to muscles on the chest.
Breast cancer can begin in different areas of the
breast: the ducts, the lobules or, in some cases, the
tissue in between. There are several types of breast
cancer, but some of them are quite rare. In some cases,
a single breast tumor can be a combination of types, or
be a mixture of invasive and in situ cancer.
Common types of breast cancer
Ductal carcinoma in situ (DCIS). DCIS is the most
common type of noninvasive breast cancer. DCIS is
called “noninvasive” because it doesn’t spread beyond
the milk duct into any normal surrounding breast
tissue. DCIS isn’t life-threatening, but having it can
increase the risk of developing an invasive breast cancer
later on in life. A client who has had DCIS is at higher
risk for the cancer coming back or for developing a new
breast cancer than a client who has never had breast
cancer before. Most recurrences happen within 5–10
years after initial diagnosis.
Signs and symptoms. DCIS generally has no signs or
symptoms. A small number of people may have a lump
in the breast or some discharge from the nipple.
Lobular carcinoma in situ (LCIS). LCIS is an area
of abnormal cell growth that increases a person’s risk
