Imaging/biopsy: You have been through a lot. Imaging with ct scan provides information and helps guide next steps, but is not diagnostic. A biopsy obtains tissue for pathology to make the diagnose of lymph node. The timing of biopsy in relation to your overall health will be best addressed between you and your doc. Take family or friend with you. ...Read more

Breast Cancer (Female) (Definition)

Breast cancer results when glandular cells lining the milk ducts and lobules of the human breast begin to grow in an unregulated manner. The growth occurs initially inside the ducts but eventually breaks outside into the breast tissue and ultimately spreads both to the lymph nodes in the armpit and via the bloodstream to other parts of the body. Because of the promoting affect of estrogen almost all breast cancer occurs in women and is a rarity in men. The unregulated growth is due to both inherited and acquired genetic defects. It is the most common malignancy in women but it often curable if found early and treated effectively with surgery, hormonal therapy, chemotherapy and targeted therapy, or a combination thereof. Early detection before the malignancy becomes large enough to be felt depends on mammography/sonography and MRI imaging of the breast on an annual basis. ...Read more

O had surgery for positive breast cancer. Is sentinel lymph node biopsy accurate for breast cancer surgery. Node was negative.

O had surgery for positive breast cancer. Is sentinel lymph node biopsy accurate for breast cancer surgery. Node was negative.

Yes they are: by now sentinel lymph node are the standard of care for breast cancer surgery and staging, and yes they are very accurate. node is negative is a very good news that will make the cancer early stage and hopefully cureable ...Read more

What is breast cancer sentinel node micro metastases?

What is breast cancer sentinel node micro metastases?

Spread of cells: Micrometastasis means that a few tumor cells have left the breast tumor and traveled to the lymph nodes under the arm. In most cases, this is treated as a negative lymph node. I encourage you to review your pathology report with your surgeon and oncologists (ideally they are communicating with each other through a meeting called a tumor board). ...Read more

Has anyone had their sentinel node out for breast cancer?

Has anyone had their sentinel node out for breast cancer?

Standard staging: The staging of invasive breast cancer almost always involves assessing the axillary nodes as the most likely 1st place cancer cells can be found outside he breast. Today this is dine via sentinel node mapping/bx to identify, remove, and test the first nod in the chain that will predict the status of the rest. On average just over 2nodes-procedure are removed. ...Read more

My friend has breast cancer. She says she needs a sentinel lymph node biopsy. What is that?

Removing a few nodes: A sentinel node biopsy means removing several lymph nodes in the chain of armpit lymph nodes. Blue dye and/or radioactivity is injected into the breast.The first armpit lymph nodes that "light up" are removed and examined for cancer cells. We know that cancer cells travel through lymph nodes in order. If the sentinel lymph nodes are negative, the others are assumed to be negative as well. ...Read more

For breast cancer can lymph nodes be tested with needle biopsy or must they 100% be removed to check them.?

For breast cancer can lymph nodes be tested with needle biopsy or must they 100% be removed to check them.?

Depends on size: Larger lymph nodes that can be felt or are over 1/2" on ultrasound can be biopsied with a needle. If that shows cancer, often no further lymph node surgery is needed NOW, but might be needed later. If no lymph nodes can be felt, and none are enlarged by ultrasound, then a "Sentinel Node Biopsy" -- removing the "sentry" or guardian lymph node of the armpit is needed; sometimes more than one. ...Read more

Do you need to remove 100% of a lymph node to check for breast cancer, or can they be checked with a needle biopsy?

Do you need to remove 100% of a lymph node to check for breast cancer, or can they be checked with a needle biopsy?

Yes: lymph nodes are only of concern if a malignant lesion of breast is present. Usually the breast tumors are small and the incidence of nodal involvement is low so that following excisional biopsy a sentinel node bx is performed removing only those nodes in the field of drainage. If a node is palpable, it is best to remove by excisional bx unless very large when aspiration can be tried. ...Read more

After a biopsy, i was diagnosed with breast cancer. The doctor said it is in the lymph nodes. I got results that came out negative but instead said metastatic breast. What does this mean?

After a biopsy, i was diagnosed with breast cancer. The doctor said it is in the lymph nodes. I got results that came out negative but instead  said metastatic breast. What does this mean?

Not clear to me: Typically, breast cancer spreads first to regional lymph nodes and then to other parts of the body. Once breast cancer spreads to the lymph nodes it is considered to have metastasized. It would be critical to understand exactly what results were "negative" to determine its significance. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Biopsy (Definition)

Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more
