Breast Cancer Breast cancer is the most common cancer among women. The American cancer society estimates that in 2002 about 192, 200 new cases of breast cancer will be diagnosed among women in the U. S. alone.
Breast cancer also occurs in men. An estimated 1, 500 cases will be diagnosed among men. In 2002, there will be about 40, 600 deaths from breast cancer in the United States. What is breast cancer? Breast cancer is a malignant tumor that has developed from cells of the breast. To make it easier I’ll put it this way. When the body needs new cells they will divide or reproduce.
Sometimes the cells grow and divide out of control, which creates a mass of tissue called a tumor. Now if the cells that are growing out of control are abnormal and don’t function like the body’s normal cells the tumor is then called malignant or cancerous. Cells from the malignant tumors can invade and damage nearby tissues and organs. They may also travel through your blood stream or lymph system to other parts of your body. If the cells are normal cells the tumor is called benign or non cancerous. This Disease occurs mostly in women, but dose occur rarely in men.
There are many stages of breast cancer. Stage 0 breast cancer is when the disease is localized to the breast and lymph nodes. Stage 1 is when the cancer is smaller than 1 inch across and hasn’t spread. Stage II is one of the following: the tumor is less than one inch but has spread to the underarm lymph nodes or the tumor is between 1-2 inches without spreading. Advanced breast cancer results after cancer cells spreads to the lymph nodes and to other parts of the body. Stage III breast cancer is also called locally advanced breast cancer.

Stage IIIB breast cancer is a tumor of any size that has spread to the Skin, Chest wall or internal mammary lymph nodes, which are located beneath the breast and inside the chest. Stage IV breast cancer is defined as a tumor that has spread to places far away from the breast, such as bones, lungs or lymph nodes.

An area that is distinctly different from any other area on either breast. There are many Types of breast cancer. The most common types of breast cancer are Infiltration Ductal Carcinoma, this is when the cancer starts in the milk ducts of the breast. Then it breaks through the wall of the duct and invades the fatty tissue of the breasts. This is the most common form of breast cancer. Ductal carcinoma in situ is ductal carcinoma in its earliest stage.
In situ it means that the cancer hasn’t spread beyond its original point. This meaning that the disease is left in the milk ducts and has not invaded nearby breast tissue. If it is left untreated it may became invasive cancer. It is almost always curable. Another kind of cancer is Infiltration Lobular Carcinoma. This cancer begins in the lobules of the breast where the breast milk is produced, but it has spread to the surrounding tissues or the rest of the body.
The Essay on Stem Cells Adult Cell Types
The history of research on adult stem cells began about 40 years ago. In the 1960 s, researchers discovered that the bone marrow contains at least two kinds of stem cells. One population, called stem cells, forms all the types of blood cells in the body. A second population, called bone marrow stroma l cells was discovered a few years later. Stromal cells are a mixed cell population that generates ...
This kind of cancer is responsible for 10-15% of breasts cancers. The last common type is Lobular carcinoma in situ is cancer that is only in the lobules of the breast. It isn’t exactly a cancer but is a sign that breast cancer might develop later, possibly in both breasts. So it is very important to have clinical breasts exams and mammograms. Breast Cancer is treated in a variety of ways depending on the size of the tumor, it’s location, the type of cancer, and a bunch of other factors. Three of the most common ways are: .
Surgery. Radiation. Chemotherapy (drug therapy) In many cases, the methods are combined to get the most effective results. Radiation is very useful in fighting cancer because it destroys cancer cells more easily than normal cells. Radiation is given with an external beam of X-rays, gamma rays or alpha and beta particles directed at the tumor. Chemotherapy is used to kill cancer cells.
It is also very useful in fighting cancer that has spread to other parts of the body. Chemotherapy can cure cancer in some cases, and help reduce the symptoms in some types of cancer. Surgery is the oldest ways to treat cancer. If the tumor is local it can be surgically removed. When this is done they also remove a border of healthy tissue is removed to ensure that all of the malignant cells have been removed.
There is no way to prevent breast cancer but there are a ton of things you can do to help reduce your risks of getting it. You should always eat foods high in fiber. Fiber helps reduce the amount of circulating estrogen in your body. Eat plenty of fruits and vegetables, also include soy in your diet.
Studies say that soy may inhibit the development and growth of cancer cells. Limit the fat in your diet, limit alcohol, and stay physically active. The Nurses Health Study found that women who exercise for at least 1 hour a day reduce their breast cancer risk by 18 %. You should also maintain a healthy weight and avoid exposure to pesticides. Because the molecular structure of some pesticides closely resembles that of estrogen.
The Essay on What Is Cancer Normal Cells
What is Cancer The article entitled "What Is Cancer?" from the American Cancer Society's web site discussed how cancer forms and effects people in different ways depending on what type of cancer they have. It also mentioned how cancers are treated and ways to prevent cancer. Cancer forms from the uncontrolled growth of abnormal cells in the body. When we are born we all have normal cells that ...
This means that they might attach to receptor sights in you body. It is known that women with high levels of pesticides in their breast tissue have a greater breast cancer risk. Although there are many different things that go along with breast cancer. This paper really helped me understand more about the subject and helped me know some of the signs that I need to look for and ways to help me reduce the risks of getting breast cancer.
