Metastatic breast cancer is also classified as Stage 4 breast cancer. The cancer has spread to other parts of the body. This usually includes the lungs, liver, bones or brain.

Ductal carcinoma in situ (DCIS) is a non-invasive cancer where abnormal cells have been found in the lining of the breast milk duct. The atypical cells have not spread outside of the ducts into the surrounding breast tissue. Ductal carcinoma in situ is very early cancer that is highly treatable, but if it’s left untreated or undetected, it can spread into the surrounding breast tissue.

The abnormal cancer cells that began forming in the milk ducts have spread beyond the ducts into other parts of the breast tissue. Invasive cancer cells can also spread to other parts of the body. It is also sometimes called infiltrative ductal carcinoma.

A diagnosis of triple negative breast cancer means that the three most common types of receptors known to fuel most breast cancer growth–estrogen, progesterone, and the HER-2/neu gene– are not present in the cancer tumor. This means that the breast cancer cells have tested negative for hormone epidermal growth factor receptor 2 (HER-2), estrogen receptors (ER), and progesterone receptors (PR).

Inflammatory breast cancer is an an aggressive and fast growing breast cancer in which cancer cells infiltrate the skin and lymph vessels of the breast. It often produces no distinct tumor or lump that can be felt and isolated within the breast. But when the lymph vessels become blocked by the breast cancer cells, symptoms begin to appear.

It is possible to be diagnosed with breast cancer during pregnancy, although it is rare and the breast cancer is not caused by the pregnancy. Women who are diagnosed with breast cancer during pregnancy have tremendous additional strain due to concern for the safety of the unborn child. It can be a traumatic and extremely difficult situation, but there is still hope for both mother and child, thanks to the many treatment options available.

Although by far, the most common breast cancer type is ductal carcinoma in situ (DCIS), there are other types that are less commonly seen. Medullary Carcinoma Medullary carcinoma accounts for 3-5% of all breast cancer types.  The tumor usually shows up on a mammogram, but does not always feel like a lump.  At times, it feels like a […]

What Is Invasive Lobular Breast Cancer? Invasive breast cancer that begins in the lobules (milk glands) of the breast and spreads to surrounding normal tissue. It can also spread through the blood and lymph systems to other parts of the body.  Invasive lobular breast cancer is the second most common type of breast cancer. Over […]

What Is Lobular Carcinoma In Situ? Lobular Carcinoma In Situ (LCIS) is a condition where abnormal cells are found in the lobules of the breast. The atypical cells have not spread outside of the lobules into the surrounding breast tissue. LCIS is highly treatable and seldom becomes invasive cancer. However, having LCIS in one breast […]
