of developing invasive breast cancer later on in life.
“Lobular” means that the abnormal cells start growing
in the lobules, the milk-producing glands at the end of
the breast ducts. People diagnosed with LCIS tend to
have more than one lobule affected.
Despite the fact that its name includes the term
“carcinoma,” LCIS is not a true breast cancer. It is an
indication that a client is at higher-than-average risk for
getting breast cancer at some point in the future.
Signs and symptoms. LCIS usually does not cause
any signs or symptoms, such as a lump or other visible
changes to the breast.
Invasive ductal carcinoma (IDC). This is the most
common type of breast cancer. IDC starts in a milk duct
of the breast, breaks through the wall of the duct and
grows into the fatty tissue of the breast. If it gets to this
fatty tissue, it may metastasize to other parts of the body
through the lymphatic system and bloodstream.
Signs and symptoms. Sometimes, the first sign of IDC
is a new lump or mass in the breast that can be felt. (See
Signs and Symptoms of IDC and ILC.)
Invasive lobular carcinoma (ILC). This second most
common type of invasive breast cancer starts in the
milk-producing lobules. Like IDC, it can metastasize to
other parts of the body. Some research has suggested
that the use of hormone replacement therapy during and
after menopause can increase the risk of ILC.
Signs and symptoms. In the beginning, ILC may not
cause any symptoms. The first sign is a thickening or
hardening in the breast that can be felt, rather than a
distinct lump. (See Signs and Symptoms of IDC and
ILC on Page 48.)
Less common types of breast cancer
Inflammatory breast cancer (IBC). This is a rare and
aggressive form of breast cancer; however, it needs to be
