Assessing metastatic involvement of the lymph nodes in breast cancer patients is important in planning surgical and adjuvant therapies. A trend toward breast-conserving therapies with the goal of improving quality of life for breast cancer patients has driven the need to accurately assess lymph nodal staging. The concept of a sentinel lymph node (SLN) biopsy is a valuable tool in evaluating metastatic spread of primary breast tumors (Maaskant-Braat et al.,2012; Noushi et al., 2013). Tokin et al. (2012) describe how the process of tumor spread via the lymphatics occurs to the first draining lymph node, then to subsequent nodes within the same basin and beyond. Breast lymphoscintigraphy has emerged as a useful means of identifying the SLN, although many patient factors, choice of radiopharmaceutical, injection technique, and imaging protocol may affect the successful outcome. The ideal exam protocol would combine speed, accuracy, and sensitivity to identifying the SLN with the least amount of burden to the patient and resources involved (Povoski et al., 2006; Sadeghi et al., 2009; Tokin et al., 2012).

Evidence of disseminate disease presence in lymph that drain the tumor area, tumor cells lodge first in the initial lymph node that receives drainage from the tumor site, once in this lymph node cells may die b/c of the lack of a proper environment, remain dormant for unknown reasons, or grow in a discernible mass, If they survive and grow cancer cells, may spread from more distant lymph nodes to the thoracic duct, and the gain access to the blood vasculature, cancer cells may gain access to the blood vasculature from the initial node and more distant lymph nodes by way of tumor-associated blood vessels that may infiltrate the tumor mass.

The development of regional lymph node recurrence is a rare event and is usually associated with a poor prognosis. It occurs more common in young women with large tumors (4). The rate of locoregional recurrence following mastectomy accounts for 9%, while it carries a 1-3% among early stage breast cancer. (17)
The N category describes whether or not the cancer has spread into nearby lymph nodes.
ILC comprises 10 % of all invasive carcinoma and it is the second common breast carcinoma but it's difficult in early detection by mammography and accounts for high false negative detection rate in all imaging techniques (Selvi, 2015).
If the lymph nodes are not inflamed, a simple sentinel lymph node biopsy may be conducted. This procedure uses a radioactive substance injected into the cancer site and the doctor will remove any nodes marked with the radioactive substance. These nodes will be analyzed microscopically looking for cancer morphology. A needle biopsy is less invasive with the doctor simply injecting a needle into a swollen lymph node and collecting tissue and cells. This kind of biopsy does have the potential to miss signs of metastasis due to lack of
SLNB has shown promising result in detecting metastatic regional lymph node in other studies, and is accepted as staging for breast carcinoma and malignant melanoma (Choi et al.,2003). In present days many guidelines are advocating SLNB for management of OSCC with clinically negative node.
Breast Cancer is a cancerous tumor that has developed within the cells of the breast. The most ordinary area in the breast for breast cancer to develop is the ducts, and less ordinary in the lobules of the breast. The cancerous cells can intrude healthy breast tissue over time, or cells can break off from the tumor and travel to the lymph nodes and into the lymphatic system which could take them to other parts of the body (“Breast Cancer-Woman’s”).
Many articles that study the breast lymphatic are claim that the deep fascia is a very poor in lymphatic [5, 6].
According to breastcancer.org, breast cancer is the uncontrolled growth of breast cells and also referred to as a malignant tumor. A malignant tumor has the potential to be dangerous and can eventually spread beyond the original tumor to other parts of the body. Breast cancer usually originates in the cells of the lobules, which are milk producing glands, or they can also begin in the ducts, which are openings that drain milk from lobules to the nipple (breastcancer.org). After time, the cancer cells attack neighboring healthy breast tissue and make way into
The incidence rates of in situ breast cancer increased by 2.8% every year between 2005 and 2009.
There are four stages of breast cancer. The Stage 0 is noninvasive breast cancer, that is, carcinoma in situ with no affected lymph nodes or metastasis. Stage zero is the most favorable. Now Stage 1 breast cancer is less than two centimeters in greatest dimension and is only in the breasts. In Stage 2, the cancer is no larger than two centimeters but it has spread to the lymph nodes under the arm. The
Over 240,000 women will be diagnosed with breast cancer in 2014 and it is estimated that 40,000 will not survive this terrible disease. Although these numbers seem daunting, believe it or not, breast cancer survival rates are actually on the incline. Many researchers and doctors believe this is due to the advances in treatment of cancers and in earlier detection which is the key in fighting almost any cancer; early detection. Women are taught to do monthly self-examinations to detect anything ‘out of the
In the United States, breast cancer is the second most common cancer in women. Although it can occur in both men and women, it is very rare in men. An individual’s breast has many components. It contains glands, ducts and breast tissue that contains fat, connective tissue, lymph nodes and blood vessels. The most common type of breast cancer in the U.S. is ducts carcinoma. This type of cancer begins within the cells of the ducts, but it can also begin in the cells of the lobules and other tissues of the breast.
Most people know breast cancer is a dangerous type of cancer that affects both men and women. Author Gayle Sulik of Pink Ribbon Blues: How Breast Cancer Culture Undermines Women 's Health describes breast cancer as, “abnormal cells [that] appear in the ducts (tubes that carry milk to the nipple) or the lobules (glands that make milk) and, more importantly, have the capacity to spread (metastasize)” (164). Breast cancer can be treated with surgeries and chemotherapy, radiation, and hormonal therapies. However, a person can still die even with treatment if the cancer metastasizes to major organs, like the brain and liver. For breast tumors and cancer to be diagnosed early, it is important to complete self-breast examinations and take the
Benign tumors grow less rapidly and are not a threat unless it continues to grow, and then the tumor must be removed. According to the American Cancer Society the second leading cause of death in America among women is breast cancer. 175,000 women and 1,300 men in America die in a year from this type of cancer; thankfully because of modern medicine this number is declining. There are various stages of breast cancer. Stage zero means that there isn’t any indication of cancer cells that have penetrated or attacked adjacent normal cell tissue. This stage best describes non-invasive breast cancer. Stage one on the other hand better illustrates invasive breast cancer; that means that the cancer cells have actually broken through and have begun invading some of the adjacent normal cell tissue. Tumors in this stage measure up to about two centimeters; the lymph nodes are not involved in the spreading of the cancer. Stage two of breast cancer is also an invasive form of cancer; in this stage the tumor has grown to at least 2 centimeters and is no more than five centimeters big. The cancer has metastasized to the lymph nodes under the armpit on the side of the tumor, but the lymph nodes have not yet stuck together or affected surrounding tissues. Stage three can be divided into two different categories. They are both invasive, but the first one describes a tumor that is larger than five
