How Often Does Stage 1 Breast Cancer Come Back After Treatment
If stage 1 cancer is treated comprehensively, it rarely comes back. A new, unrelated breast cancer is more likely to emerge after stage 1 breast cancer is treated than a recurrence. Your healthcare provider will recommend a surveillance schedule for you so that new breast cancer or a recurrence can be identified and treated as quickly as possible.

In recent years, developments in breast cancer have allowed yet another realization of individualized medicine in the field of oncology. One of these advances is genomic assays, which are considered elements of standard clinical practice in the management of breast cancer. These assays are widely used today not only to measure recurrence risk in breast cancer patients at an early stage but also to tailor treatment as well and minimize avoidable treatment side effects. At present, genomic tests are applied extensively in node negative disease. In this article, we review the use of these tests in node positive disease, explore their ramifications on neoadjuvant chemotherapy decisions, highlight sufficiently powered recent studies emphasizing their use and review the most recent guidelines.
Less Lymph Node Surgery Equivalent Survival
The trial, called ACOSOG Z0011, was designed to compare whether sentinel lymph node biopsy alone provided equivalent survival benefits to ALND after breast-conserving surgery among a subset of women who also received radiation and systemic therapy. The research team enrolled 891 participants into the study from 1999 to 2004.
Women who had stage I or II cancer and metastases in only one or two sentinel nodes were eligible to join the study. All women had undergone SLNB at the time of breast-conserving surgery.
Half of the trial participants received no further surgery, and the other half underwent ALND. Almost 90% of women in both groups had radiation therapy after surgery, and almost all received some type of systemic therapy.
In the initial results from the trial, published in 2010 and 2011, women who had only SLNB did not have worse overall survival than women who underwent full ALND. The two groups also had similar rates of disease-free survival and cancer recurrence in the lymph nodes.
These early results were absolutely practice changing, and at this point the overwhelming majority of surgeons are not doing a full axillary lymph node dissection in patients with one or two positive nodes, said Larissa Korde, M.D., head of Breast Cancer Therapeutics in NCIs Division of Cancer Treatment and Diagnosis.
However, the cancer research community had lingering concerns about the trial, the authors of the new paper explained.

Stage Iv Breast Cancers May Be Recurrences Following Initial Treatment
Up to 5% of initial breast cancer diagnoses are of the most advanced or metastatic stage. However, this number has significantly reduced with the implementation of widespread breast cancer screening programs.
Metastatic breast cancer can appear to be a rapid deterioration of a disease that has been present for some time undetected.
But metastatic breast cancer can also be the result of a recurrence of breast cancer after successful initial treatment. Sometimes the terms local and regional recurrence indicate a return of breast cancer to the original tumor site or elsewhere in the breast or contralateral breast.
If the cancer returns in other areas of the body it is a distant metastasis or distant recurrence.
For more detail on Stage IV survival rates, recurrence rates and treatment please see our new post HERE.
Diagnosing Cancer Of The Lymph Nodes
In addition to a biopsy, the TNM system is commonly used to issue a diagnosis and determine which type of treatment is best. The T refers to the size of the tumor or cancerous growth. The N refers to the number of lymph nodes that contain cancerous cells. And, the M is for metastasis, which refers to cancer thats spread to areas far from the originating tumor.5
This categorization is used in addition to other diagnostic tests and tools to determine the cancer stage such as:
- Imaging tests X-rays, CT scans, MRIs, and other types of imaging tests can provide a clearer picture and more information about where the cancer is located and how much is present.
- Endoscopy exams An endoscope is a thin, lighted tube with a video camera attached that looks around on the inside of the body for cancerous areas.
In general, cancers assigned as Stage I are less advanced and have a better prognosis and response to treatment. Whereas, a higher stage indicates that the cancer has spread further and requires a more intense or multiple types of treatment. Other factors that affect treatment are:

What Is Breast Cancer In Men
Breast Cancer in men is a type of cancer that occurs in the non-functional milk ducts, glands, and breast tissues. Mens breasts have fatty tissues, breast cells, and ducts. Breast tissues in men are similar to that of a pre-puberty girl. These tissues in men do not grow much because they have low levels of female hormones. Cancer develops when healthy cells grow out of control, forming a mass of cells called a tumor.
A tumor can be malignant or benign. The tumor is malignant if it grows and spreads to other parts of the body. On the other hand, a benign tumor can grow but doesnt spread to other body parts. When Breast Cancer spreads to the other body parts through the lymph or blood, it is called metastasis.
Are There Symptoms Of Breast Cancer In The Lymph Nodes
You probably wouldnt notice if a few cancer cells reached a lymph node. As the number of cancer cells grows, symptoms can include lumps or swelling in the armpits or around the collarbone.
Its possible to have enlarged lymph nodes even if you havent discovered a lump in your breast. There are also noncancerous conditions that cause enlarged lymph nodes in an area close to the breasts.
If you notice enlarged lymph nodes but no other symptoms or signs, schedule an appointment with a doctor.

Axillary Lymph Node Dissection
In this procedure, anywhere from about 10 to 40 lymph nodes are removed from the area under the arm and checked for cancer spread. ALND is usually done at the same time as a mastectomy or breast-conserving surgery , but it can be done in a second operation. ALND may be needed:
- If a previous SLNB has shown 3 or more of the underarm lymph nodes have cancer cells
- If swollen underarm or collarbone lymph nodes can be felt before surgery or seen on imaging tests and a FNA or core needle biopsy shows cancer
- If the cancer has grown large enough to extend outside the lymph node
- If the SLNB is positive for cancer cells after chemotherapy was given to shrink the tumor before surgery
Adjuvant Treatment May Include Completion Axillary Lymph Node Dissection
Typical follow-up treatments after the detection of micrometastasis in the sentinel node might include axillary radiation or completion axillary lymph node dissection. With no followup treatments the rate of axillary lymph node metastasis for women who show micrometastasis in the sentinel node is perhaps 5%, but for women who undergo adjuvant therapy, that rate drops to about 1%. So the question remains, is it worth it? Axillary node radiation can cause skin tightness and other effects in the axilla region, and axillary lymph node dissection surgery can have the risk of causing lymphedema swelling in the arm.

Why Are Axillary Lymph Nodes Important
Knowing your lymph node status helps determine which combination of therapies are best for treating your unique cancer. Only about 30% of all patients diagnosed with invasive breast cancer are found to have cancer in their lymph nodes. If cancer travels to the lymph nodes, these cells typically go to the axillary lymph nodes under the arm on the same side of the newly diagnosed breast cancer. These cells usually lodge in the first 1, 2, or 3 lymph nodes and grow there. Research suggests that cancer typically spreads to the sentinel nodes before the other 10 to 20 axillary nodes everyone has under the arm.
If you are found to have cancer in your lymph nodes, you will likely be offered chemotherapy if you can tolerate it. It is less likely you will need chemotherapy if your lymph nodes are negative. Your lymph node status is one of many factors in deciding your treatment options.
Lymph Node Surgery For Breast Cancer
If breast cancer spreads, it typically goes first to nearby lymph nodes under the arm. It can also sometimes spread to lymph nodes near the collarbone or near the breastbone . Knowing if the cancer has spread to your lymph nodes helps doctors find the best way to treat your cancer.
If you have been diagnosed with breast cancer, its important to find out how far the cancer has spread. To help find out if the cancer has spread outside the breast, one or more of the lymph nodes under the arm are removed and checked in the lab. This is an important part of staging. If the lymph nodes have cancer cells, there is a higher chance that cancer cells have also spread to other parts of the body. More imaging tests might be done if this is the case.
Lymph node removal can be done in different ways, depending on whether any lymph nodes are enlarged, how big the breast tumor is, and other factors.

M Categories For Breast Cancer
M followed by a 0 or 1 indicates whether the cancer has spread to distant organs — for example, the lungs, liver, or bones.
M0: No distant spread is found on x-rays or by physical exam.
cM0: Small numbers of cancer cells are found in blood or bone marrow , or tiny areas of cancer spread are found in lymph nodes away from the underarm, collarbone, or internal mammary areas.
M1: Cancer has spread to distant organs as seen on imaging tests or by physical exam, and/or a biopsy of one of these areas proves cancer has spread and is larger than 0.2mm.
Sentinel Lymph Node Biopsy
In a sentinel lymph node biopsy , the surgeon finds and removes the first lymph node to which a cancer is likely to spread . A radioactive substance and/or a blue dye is injected into the tumor, the area around it, or the area around the nipple. Lymph vessels will carry these substances along the same path that the cancer would likely take. The first lymph node the dye or radioactive substance travels to will be the sentinel node.
After the substance has been injected, the sentinel node can be found either by using a special machine to detect radioactivity in the nodes, or by looking for nodes that have turned blue. Sometimes, both methods are used. The surgeon cuts the skin over the lymph node area and removes the node containing the dye or radioactivity.
The few removed lymph nodes are then checked closely in the lab for cancer cells by a pathologist. Sometimes, this is done during the surgery. Because there is a chance that other lymph nodes in the same area will also have cancer if cancer is found in the sentinel lymph node, the surgeon may go ahead with an axillary dissection to remove more lymph nodes while you are still on the operating table. If no cancer cells are seen in the node at the time of the surgery, or if they are not checked by a pathologist at the time of the surgery, they will be examined more closely over the next several days.
Based on the studies that have looked at this, skipping the ALND may be an option for:

What Happens After A Sentinel Node Biopsy
If the lymph nodes do not contain cancer cells, you wont need to have any more nodes taken out.
If cancer cells are in the sentinel nodes, you have another operation to remove most or all of the lymph nodes under your arm. This is an axillary lymph node dissection or clearance. You generally have it about 2 weeks after you get the results.
Some people have radiotherapy to the armpit to destroy any remaining cancer cells instead of surgery.

Symptoms Of Secondary Breast Cancer
Secondary breast cancer means that a cancer that began in the breast has spread to another part of the body. Secondary cancer can also be called advanced or metastatic cancer.
It might not mean that you have secondary breast cancer if you have the symptoms described below. They can be caused by other conditions.

Where Does Breast Cancer Spread To
Breast cancer cells seem to prefer to settle into:-
- long bones in the arms and legs
With an osteolytic metastasis, the cancer kind of eats away at the bone, creating holes.
With an osteoblastic bone metastasis, the bone mineral density actually increases, but this can cause the bones to fracture more easily. This requires a little more explanation. Breast cancer metastases tend to be lytic when they are untreated, and then they become densely sclerotic as they respond to treatment.
Even if no treatment is given yet, an osteoblastic metastasis from breast cancer generally indicates that the persons own body is trying to fight cancer with some success.
A CT scan may also be used to check for metastasis to the lungs or liver. A CT scan is essentially an X-ray linked to a computer. The breast cancer doctor injects a contrast dye agent into the bloodstream and this makes any cancer cells in the liver and chest easier to see.
Types Of Lymph Node Surgery
Even if the nearby lymph nodes are not enlarged, they will still need to be checked for cancer. This can be done in two different ways. Sentinel lymph node biopsy might be needed.
Lymph node surgery is often done as part of the main surgery to remove the breast cancer, but in some cases it might be done as a separate operation.

If I Am Over 70 Can I Avoid A Sentinel Node Biopsy
It is possible. If you are in your 70s and are active and healthy, you should proceed with a sentinel node biopsy if it is recommended. You will likely be able to tolerate the surgery. The information gained about your cancer could change your therapy.
For those who are older and struggling health wise, it is worth discussing with your breast surgeon if a sentinel node biopsy is even needed. If someone is weak and struggles to move independently, any surgery performed under the arm can make these essential activities more difficult. If you are not healthy enough to even consider chemotherapy, a lymph node surgery may not provide you helpful information.
This page about Sentinel lymph node biopsy and axillary dissection outlines the two procedures. This site is created for patients by the American Society of Breast Surgeons.

The Korean Breast Cancer Registry
All data used in this study were retrieved from the Korean Breast Cancer Registry , which has prospectively maintained an online database to store information on each patients Korean personal identification number, age, type of surgery, primary tumour size, number of positive/dissected nodes, oestrogen receptor /progesterone receptor status, histologic grade, and details of adjuvant therapy. Nation-wide collaborative efforts from 102 general hospitals, including 41 university hospitals, have contributed to the KBCR database since 1996 . Exploiting the patients identification number as a unique identifier, we amalgamated the KBCR database with two population-based sources of information: the Korean Central Cancer Registry, which provides patients survival data, and the Korean National Statistical Office, which publishes complete death statistics.

Breast Cancer In Lymph Nodes
When you have breast cancer in your lymph nodes, the cancer has spread beyond the breast tissue. Breast cancer is most often genetically linked and caused by the growth of abnormal breast cells. In normal cells, they die off and new cells grow. Cancer cells just keep growing mutated cells that form into tumors. This article will explain how breast cancer invades the lymph nodes and spreads to other tissues and organs.
Limited Arm And Shoulder Movement
You might also have limited movement in your arm and shoulder after surgery. This is more common after ALND than SLNB. Your doctor may advise exercises to help keep you from having long-lasting problems .
Some women notice a rope-like structure that begins under the arm and can extend down toward the elbow. This is sometimes called axillary web syndrome or lymphatic cording. It is more common after ALND than SLNB. Symptoms may not appear for weeks or even months after surgery. It can cause pain and limit movement of the arm and shoulder. This often goes away without treatment, although some women may find physical therapy helpful.
