Causes And Treatments Of Breast Cancer

Breast cancer is a disease in which certain cells in the breast become abnormal and multiply uncontrollably to form a tumor. Breast cancer is the second most commonly diagnosed cancer in women. (Only skin cancer is more common.) About one in eight women in the United States will develop invasive breast cancer in her lifetime. Researchers estimate that more than 230,000 new cases of invasive breast cancer will be diagnosed in U.S. women in 2015. Cancers occur when a buildup of mutations in critical genes—those that control cell growth and division or repair damaged DNA—allow cells to grow and divide uncontrollably to form a tumor. Breast cancer can be caused by inherited genetic factors. These genetic

“Cancer” is the name for a group of diseases that start in the body at the cellular level. Even though there are many different kinds of cancer, they all begin with abnormal cell growth with the potential to invade or spread to other parts of the body. These abnormal cells lump together to form a mass of tissue or “malignant tumor”. Malignant means that it can spread to other parts of the body or Metastasize . If the breast is the original location of the cancer growth or malignant tumor, the tumor is called breast cancer. (American Cancer Society, 2014, as cited in cbcf.org)

Breast cancer is a malignant tumor that begins in the breast ("Florida Department of Health," n.d.). A malignant tumor can invade surrounding tissues or spread to other areas of the body. Breast cancer is predominantly a disease among women and is the most common type of cancer among women in the United States.

“Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems (NCI, 2013).” Cancer is of many diseases. It originates from the organ in the body and/or from the part of the body that is affected, for example breast cancer. Breast cancer is mainly common among women, except for skin cancers. “Breast cancer occurs when cells in the breast divide and grow without their normal control (Komen, 2014).” The

A cancer cell is formed when the cell’s DNA is damaged but not repaired. Instead of the cell dying, like a normal cell, it reproduces new cells which also have the damaged DNA that the original cell had. Factors that can cause a cell to be damaged are mistakes during the reproduction of the cell, environmental reasons, such as smoking or too much sun exposure. The cancer cells form tumors which then invade the tissue of a certain body part, like the breast, lungs, brain, or prostate. Cancer can spread sometimes from body part to body part, but is named from where it starts. For instance, if somebody were to be diagnosed with breast cancer, and developed cancer in their lungs, it would be metastatic lung cancer. Metastasis is how cancer can spread to other body

Breast Cancer is made up of glands also known as lubes. In a women breast the small tubes (lobules) carry milk to the nipples (ducts) . Breast cancer begins in the cells that are in the in the ducts. It can also start in other cells of the breast tissues. There is a pathway in the breast called lymph. Lymph causes the cancer to spread throughout the breast. The vessels that carry clear fluid instead of blood connect lymph.

Breast cancer is defined as a malignant tumor in the cells of the breast. A cancerous tumor develops when a group of malignant cells invade the tissue surrounding the breast and can spread to other parts of the body (Cancer.org, 2015). This type of cancer is most common in women. However, men can also fall victim to the disease. In 2015, about 230,000 new cases of breast cancer will be diagnosed in women and approximately 40,000 women will die from this disease (Cancer.org, 2015).

“Breast cancer is a malignant tumor that starts in the cells of the breast. A malignant tumor is a group of cancer cells that can grow into (invade) surrounding tissues or spread (metastasize) to distant areas of the body. The disease occurs almost entirely in women, but men can get it, too.” (Society, 2015) There is a

Cancer is when abnormal cells divide in an uncontrolled way and develops when the body’s normal control mechanism stops working. Cancer cells are different than normal cells in many ways that allow them to develop out of control and become invasive. Normal cells mature into distinct cell types with particular functions and cancer cells do not. Unlike normal cells, cancer cells continue to divide without stopping. Many cancers form solid tumors, which are masses of tissue. Tumors can be malignant or benign. Unlike malignant tumors, benign tumors do not invade tissues that are near. Cancerous tumors are malignant, which means these tumors invade tissues. A cancer that has spread from where it started to other places in the body is called metastatic cancer. The process is called metastasis. Treatment may help prolong the lives of some people with metastatic cancer.

Cancer is the abnormal growth of cells, or as cell malignancy. There are various forms of cancer, and mostly,

Before going in depth, let us first define what breast cancer is. According to the National Breast Cancer.Org “Cancer is a broad term for a class of diseases characterized by abnormal cells that grow and invade healthy cells in the body. Breast cancer starts in the cells of the breast as a group of cancer cells that can then invade surrounding tissues or spread (metastasize) to other areas of the body.” Cancer begins in the cells which are the basic building blocks that make up tissue. Tissue is found in the breast and other parts of the body. Sometimes, the process of cell growth goes wrong and new cells form when the body doesn’t need them and old or damaged cells do not die as they should. When this occurs, a build up of cells often forms a mass of tissue called a lump, growth or tumor.

According to the National Cancer Institute, Cancer is “a term for diseases in which abnormal cells divide without control and can invade nearby tissues. Cancer cells can also spread to other

Cancer is the abnormal growth of cells which tend to proliferate in an uncontrolled way and, in some cases, to metastasize. Most cancers are named for the type of cell or organ in which they start. If a type of cancer spreads, the new tumor bears the same name as the original tumor. The most common types of cancer are breast, lymphoma, leukemia, colon, prostate, ovarian, and lung cancers. Each cancer has its own way of forming and different causes and effects on the body. While some can be treated there are types of cancers that are a terminal illness.

Breast cancer is a type of cancer that forms in the cells of the breast. It starts when the cells in the breast start to grow out of control. The cells will usually form a tumor and it can be felt as a lump or on an x-ray. If the tumor is malignant it can spread to other parts of the body. It occurs mostly in women, but what many don’t know is that men can get it too.

Accountable for the vast majority of cancer deaths, metastasis is the complex process by which the cancer cells spread from the primary site to distant sites throughout the body by way of increased tumor invasiveness. Tumor cells persist in replication and may inadequately differentiate into specialized cells as they attain an aggressive manner. Given that it is among the most commonly diagnosed cancers in the United States, approximately 1 in 8 women and 1 in 1,000 men in America may develop breast cancer throughout their life. Via the bloodstream or lymphatic system, main sites of metastasis in breast cancer are the bone, brain, liver, and lung. In view of the fact that breast cancer is immunogenic, tumor development and progression may be directly associated with immunosuppressive factors. On account of an expansion or increase of activation in CD8+ T cells and inhibition or decrease in myeloid-derived suppressor cells (MDSCs), the tumor associated macrophages (TAMs) may allow for immune suppression in breast cancer patients. In a similar manner, standard immunotherapy and checkpoint blockade brings about an optimal clinical response in the regulation of immunity. Scientific research and publications regarding mutations on the BRCA1 and BRCA2 genes will be discussed in this term paper to reflect on the lengths of multiple aspects of breast cancer metastasis by way of cellular processes of clinical patterns in the tumor microenvironment. The assessment studies may provide
