What happen if breast cancer spread to lymph nodes?

When breast cancer is found in the lymph nodes, it means that cancer has spread from the primary tumor and is at least stage 2. Lymph node involvement is an important part of staging and in determining which treatments are most likely to be effective.

What percentage of breast cancer spreads to lymph nodes?

Outlook for cancer that has spread to lymph nodes can depend on the type of cancer a person has. For example, the American Cancer Society (ACS) defines the 5-year survival rate as follows once the cancer has regionally advanced, including spread to the nearby lymph nodes: 86% for breast cancer.

Is lymph node positive breast cancer curable?

If the cancer has spread to regional lymph nodes, cure is still the goal, but a proportion of women with node-positive cancer will also have subclinical metastatic disease that may or may not be cured by surgery and systemic chemotherapy.

What if cancer is found in lymph nodes?

Cancer appearing in the lymph nodes is an indicator of how the cancer is spreading. If cancer cells are only found in the lymph nodes near the original tumor, it may indicate the cancer is in an earlier stage and has not spread far beyond its primary area.

Can a doctor tell if cancer has spread to lymph nodes?

Lymph nodes deep in the body cannot be felt or seen. So doctors may use scans or other imaging tests to look for enlarged nodes that are deep in the body. Often, enlarged lymph nodes near a cancer are assumed to contain cancer. The only way to know whether there is cancer in a lymph node is to do a biopsy.

What happens when breast cancer spreads to lymph nodes?

When there is breast cancer in your lymph nodes, you may not notice any symptoms at all. In fact, it is not until the lymph nodes are overloaded with cancer and swollen that you may notice a lump in the underarm or even swelling of the arm or breast on the same side. Once breast cancer leaves the lymph nodes, it is considered metastatic, or stage IV.

Can breast cancer spread despite clear lymph nodes?

To help find out if the cancer has spread outside the breast, one or more of the lymph nodes under the arm (axillary lymph nodes) are removed and checked in the lab. This is an important part of staging. If the lymph nodes contain cancer cells, there is a higher chance that cancer cells have also spread to other parts of the body.

Does “problem” with the lymph nodes always mean cancer?

When you have strep throat, lymph nodes in your neck may swell. Women who have breast cancer may get swollen lymph nodes in their armpit. When several areas of lymph nodes are swollen, that suggests the problem is throughout your body. It could be something like chickenpox, HIV, or a cancer such as leukemia or lymphoma.

How is the lymph system involved in breast cancer?

Microscopic (or minimal): Only a few cancer cells are in the node. A microscope is needed to find them.
