Metastatic breast cancer can develop when breast cancer cells break away from the primary tumor and enter the bloodstream or lymphatic system. These systems carry fluids around the body. The cancer cells are able to travel in the fluids far from the original tumor.

What is the relationship of the lymphatic system to the breast?

Lymphatic circulation in breast tissue helps regulate the local fluid balance as well as filter out harmful substances. But the breast’s lymphatic system can also spread diseases such as cancer through the body. Lymphatic vessels provide a highway along which invasive cancerous cells move to other parts of the body.

Where are your breast lymph nodes?

The axillary lymph nodes run from the breast tissue into the armpit. This area under the arm is called the axilla. During an axillary lymph node dissection, anywhere from 10 to 40 lymph nodes are removed and examined. These nodes are typically removed during your lumpectomy or mastectomy.

When cancer spreads through the lymph nodes the term is called?

Cancer that starts in one part of the body (primary cancer) can spread to other parts of the body. It does this through the bloodstream or the lymphatic system. Primary cancer of the lymph nodes is called lymphoma. This is when cancer starts in the lymph nodes.

What is a benign lymph node in the breast?

How many lymph nodes are in the breast?

The body has about 20 to 40 bean-shaped axillary lymph nodes located in the underarm area. These lymph nodes are responsible for draining lymph – a clear or white fluid made up of white blood cells – from the breasts and surrounding areas, including the neck, the upper arms, and the underarm area.

How does breast cancer affect the lymphatic system?

Breast cancer and lymph nodes

Sometimes, cancer can spread through the lymphatic system. If breast cancer cells spread outside the breast, they are most likely to go to lymph nodes in the armpit. You will usually have tests to look for cancer cells in the lymph nodes.

Is breast cancer in lymph nodes metastatic?

The lymph nodes under your arm, inside your breast, and near your collarbone are among the first places breast cancer spreads. It’s “metastatic” if it spreads beyond these small glands to other parts of your body.

What does breast cancer do to the lymphatic system?

Vascular or lymphatic system invasion happens when breast cancer cells break into the blood vessels or lymph channels. This increases the risk of the cancer traveling outside the breast or coming back in the future. Doctors can recommend treatments to help reduce this risk.

What are some nodes that receive lymph drainage from the breast?

More than 75% of the lymph from the breast goes to the axillary nodes. Other points of drainage are to pectoral nodes between the pectoralis major and minor muscles and to the subclavicular nodes in the neck deep to the clavicle.

What does a lymph node in breast feel like?

Axillary lymph nodes often feel like small, round sponge like masses under the skin. They may be painful to the touch. A doctor will investigate if cancer has spread to the lymph nodes by performing a physical examination or an ultrasound.

How do I know if my lymph nodes are swollen in my breast?

Sometimes, positive lymph nodes can be felt during a physical exam. However, a pathologist’s exam of the lymph nodes removed during a biopsy or surgery is needed to determine lymph node status. During a physical exam, your health care provider will feel under your arm to check if the lymph nodes are enlarged.
