Lymph nodes: Frequently Asked Questions
What are lymph nodes?
Lymph nodes are part of the lymphatic system which carries waste products and other materials away from the cells in your body. Lymph nodes filter this material before it returns to the blood stream. They also store WBCs (lymphocytes) and help fight infection. The nodes under your arm are called axillary nodes and are important in determining the breast cancer stage and spread. If cancer cells are present in the axillary nodes there is a higher chance that the cancer may have spread. ...

Lymph nodes are small round shaped glands that are about the size of a pea or baked bean. The body contains more than 500 lymph nodes. Lymph nodes help prevent the spread of infection and protect the bloodstream from viral and bacterial invasion. Normal nodes are largest at age 10 to 12 years. At this age they can be twice the normal adult size. The easiest to feel are in the neck, armpit, or

What are lymphatics and lymph nodes?
Lymphatics collect tissue fluid throughout the body including the extremities and return it to the large veins near the heart. The lymph represents fluid that originates as the circulation passes through the tissues. The lymph passes through filtering sites called lymph nodes along the way back to the heart. [ Back to top ]

Can lymph nodes be removed during the dVP?
Yes. Staging lymphadenectomy can be performed if clinically warranted. Fortunately, since the availability of PSA testing, prostate cancer is typically diagnosed at a much more favorable stage thereby lessening the need for lymph node removal. to top

Does the underarm incision affect the lymph nodes under the arm?
This incision should not interfere with breast lymph node drainage. The incision is high in the armpit, more superficial and anterior than the nodes. The dissection and placement of the implant are over the pectoral muscle and under the fascia, again, superficial to the nodes.

How many lymph nodes are removed during axillary dissection?
Axillary dissection is performed on patients whose breast cancer has spread to the lymph nodes or who are not candidates for sentinel node biopsy. The lymph nodes are buried in fat and cannot be seen during surgery. Most women have 10-30 underarm lymph nodes. In axillary dissection, the surgeon removes the pad of fat containing these lymph nodes. Following surgery, the tissue is examined under a microscope to determine how many lymph nodes were removed and whether any contain cancer cells (This takes about 5 days.). ...

What is the clinical significance of finding palpable lymph nodes?
Normally, the lymph nodes are not visible or palpable. If the lymph nodes are palpable, it may indicate infection or inflammation. Nontender, firm, hard lymph nodes that are nonmovable may indicate a malignancy. Palpable, firm, or hard lymph nodes warrant further assessment and diagnosis.

Should the lymph nodes also be removed during robotic prostate surgery?
Basically yes. However, many Urologic surgeons will not remove the lymph nodes for patients with extremely focal and early disease. This decision should be made between you and your trained robotic-surgeon.

Where are Lymph nodes? Is it common for cancers to spread there, it seems as if I've heard that it is?
Lymph nodes are found throughout the body and are usually the first site of metastatic spread of cancers. For example, FNA could be particularly useful in patients with an established diagnoses of cancer who subsequently presents with enlargement of a lymph node(s). Yes, it is common for cancers to spread to lymph nodes.

How can I tell if my cancer has spread beyond my breast or beyond my lymph nodes, if my lymph nodes are positive?
Its important to know that breast cancer doesn't always spread directly to the lymph nodes. It can travel beyond the breast directly through the blood stream and lymph system even if the lymph nodes are negative. That is why in some cases, especially with large or aggressive tumors, it is necessary to use chemotherapy even if no lymph nodes are affected. CT scans and bone scans should be done if your physician feels that there may be a chance of metastasis. ...

Do I obtain functional measurements on a patient with negative sentinel nodes, but positive lymph nodes in her axillary dissection?
Yes, as long as the sentinel nodes are negative, the functional measurements must be done. It does not matter is the axillary dissection was positive or not.

For tumours of upper thoracic oesophagus what is the difference between pN1 and pM1a, because the definition of regional lymph nodes of the cervical oesophagus includes supraclavicular lymph nodes?
For the thoracic oesophagus, including the upper thoracic, the cervical lymph nodes are not regional nodes. For the cervical oesophagus, the regional nodes are the cervical nodes. (See TNM 6th ed., p. 61.)

Can these imaging techniques show irregularities or tumor involvement in chest wall, pericardium, diaphragm, and lymph nodes?
CT scans can show chest wall and pericardium involvement, but MRIs are generally more accurate in assessing lymph node and/or diaphragm involvement. PET and PET/CT scans are considered the best images to determine staging and surgical candidacy and to track the effects of treatment.

When a lymph node(s) is biopsied prior to surgical resection, is that node(s) to be included when calculating nodes examined/evaluated in Collaborative Stage?
Yes, regional lymph nodes positive and examined are cumulative fields. (See Instructions for Data Items, Regional Nodes Positive, Instruction 4a; and Instructions for Data Items, Regional Nodes Examined, Instruction 4a) (9/23/04) Back to the top

What is the treatment for a patient who has enlarged lymph nodes and involvement of the lungs, spleen, and liver. The patient also has diabetes mellitus?
Although prednisone would be an ideal drug, in this case the presence of diabetes mellitus is contraindicated. Hydroxychloroquine and methotrexate should be tried.
In gastric carcinoma, is the presence of positive lymph nodes/tumour nodules in omentum considered N or M1?
If they are close to the stomach (in the lymph drainage area) N 1-3 is likely; if they're far from the stomach, M1 seems reasonable. If you are in doubt, use TNM Rule No. 4, when in doubt choose the lower category (M0).

My breast cancer spread to my lymph nodes. Can FEMARA help reduce my risk of cancer coming back?
For women whose cancer has spread to the lymph nodes, the risk of relapse may be more significant. Oncologists may recommend FEMARA due to results from a clinical trial which showed that FEMARA was more effective than tamoxifen by 29% at reducing the risk of cancer returning in women with node-positive breast cancer 1 . 185 out of 1,660 (11.1%) patients taking FEMARA recurred versus 247 out of 1,651 (15%) patients taking tamoxifen.

Q: What are Lymph nodes?
The Lymph nodes are filter stations and gathering points or "Lymph flow junctions" where Lymph channels in the body come together. The Lymph system, its importance to health, and its functions are not well understood within today's medical circles, and therefore its descriptions and functions may be not well understood nor well-defined by current-day medical literature.

Is there a way of knowing whether or not cancer has spread from one’s lymph nodes or from one’s breast into other surrounding regions?
One might consider it important to know whether or not cancer has spread from one’s lymph nodes or breast to other regions in the body. It must be noted that even of the lymph nodes are not cancerous, cancer can still spread through the blood stream. This is the reason why in some cases it becomes important for one to use chemotherapy to remove large tumors even though one’s lymph nodes may not be affects.

In tumours of the breast, how do we classify invasion of lymphatic vessels in paranodal fatty tissue of the axilla with and without involvement of the axillary lymph nodes?
Invasion of lymphatic vessels in the axilla is not considered in the TNM classification of breast tumours. The optional L (lymphatic) classification (TNM 6th ed., p. 14) can be used to describe lymphatic vessel involvement.

I have some symptoms like swollen lymph nodes, night sweats, etc. What's the risk I have HIV/AIDS?
No one can diagnose anything over the Internet. Anyone with symptoms that are persistent, severe, or possible indicators of a serious condition should see a doctor. Describe your sexual history and risk factors for HIV, get tested for HIV, and follow any instructions the doctor gives you (like follow-up testing). Watch our videos "Do I Have AIDS? Symptoms of AIDS" and "Why EVERY Person Should Be Tested for HIV. " Go to AIDSvideos dot org and click "Symptoms" to learn more. ...

I had lymph nodes removed and my doctor said I may develop lymphadema. What is that and do have any products that will help me?
Lymphadema is a swelling of the arm or breast due to an accumulation of lymph fluid that occurs when lymph nodes are blocked or removed. Not to be alarmed; this condition occasionally happens. One way of preventing lymphadema is to be measured for a lymphadema sleeve. We strongly feel every woman should have a sleeve if they are traveling via an airplane. The pressure changes in flight can cause the lymph fluid to change and hopefully this condition can be prevented by wearing a sleeve 1 – 2 hours both pre and post flight. ...

My friend read about a melanoma test that can show whether melanoma has spread to lymph nodes, and can pick out the exact nodes that have cancer cells. Should I ask the doctor about this test?
The test is a sentinel lymph node biopsy. Many doctors feel that it can help in more accurately deciding the stage of a melanoma. It usually begins with lymph node "mapping," which identifies the exact lymph node basin where fluid from the tumor site drains. The fluid may carry cancer cells. Doctors biopsy the first node in the basin, remove it and have it examined for cancer cells. If positive the remaining nodes are removed. If the sentinel node is negative, it avoids the need to remove presumably normal lymph nodes. ...
