Breast Cancer | Borka Association for Cancer
Breast cancer is the abnormal growth and uncontrolled division of cells in the breast. These malignant cancer cells form a mass (tumor) that attack and destroy surrounding healthy tissue. Cancer cells that are separated from the tumor have the ability to spread through the circulatory and lymphatic system of the breast to distant parts of the body to attack other tissues and form new tumors. This process is called metastasis. If not controlled metastases, breast cancer shemagh can result in death.
Description breast of a woman is made up of groups of cells (glands) which, when stimulated by the appropriate hormones secrete milk into a network of small tubes (ducts) that collect the milk and bring it to the nipple. Breast also contains fatty tissue, lymph and blood vessels. Breast cancer usually starts in the cells along the ducts (ductal cancer). Groups of glands in the breast tissue called lobules. The cancer also can start in lobules (lobular cancer) and very rarely in other tissues of the breast. shemagh Depending on where the cancer starts in the breast, the disease develops certain characteristics that are used to classify breast cancers into subtypes. The larger classification of disease is associated with tumor stage or ability to invades and spreads, making this characteristic defines disease as a true cancer. Stages before invasive cancer is called carcinoma in situ, which means that early malignancy in one place and have not spread.
Primary tumor begins in the breast, but when it becomes shemagh invasive, cancer cells can move out of the breast in the regional lymph nodes. Cells from the tumor also break off and travel through the lymphatic shemagh system and blood vessels in other parts of the body where new tumors form. This process is called metastasis.
In the breast, the primary nodes are under the armpit or axilla. Typically, a primary tumor that starts in the breast first spread to regional lymph nodes under the arm. Cancer cells also can affect the blood vessels of their place of origin. When cancer cells enter the blood vessels, circulatory system provides a way for cancer to spread shemagh to distant parts of the body. Breast cancer tends to follow this progression, although he is often widespread at the beginning of the disease.
By the time you can feel a lump in the breast, often 1 cm in diameter and contains approximately one million cells. Estimates suggest that it takes from 1 to 5 years for a tumor to develop this size. During that time, the cancer cells can spread to other parts of the body. The most common sites for distant spread shemagh of breast cancer to the lungs, bones, liver, skin and soft tissues. The number of regional lymph nodes containing cancer cells remains only the most reliable indicator of whether the cancer metastasized widely. Because tests for the detection shemagh of metastases in other organs are not sufficiently sensitive to detect small tumors, evaluation of axillary nodes regional metastases is important in making decisions about the treatment of any given case. If breast cancer spreads to other major organs of the body, its presence will compromise the function of these organs. Compromise the functioning of vital organs can cause death.
Every woman is at risk for getting breast cancer. If that experience 85 years has one of eight (12%) chance that she will develop breast cancer at some time during shemagh her life. As a woman ages, her risk of developing breast cancer rises dramatically regardless of her family history. The risk of breast cancer, 25-year-old woman is only a woman of 19,600, for 45 years, shemagh he is a woman of 93. Less than 5% of cases are discovered before the woman turned 35 years and the majority of the total number of breast shemagh cancers are found in women over age 50. About 40,000 women die of breast cancer each year. More cases of breast cancer are diagnosed because of increased use of screening mammograms, however, deaths from breast cancer are declining because the disease is diagnosed early, more izlechlivi stages.
Causes and symptoms All cancers are thought to arise due to small changes (mutations) in genes. Mutations that cause breast cancer do not have a single cause. Genetic shemagh and environmental factors and lifestyle play a role in getting breast cancer.
Risk factors include: - Age. 80% of breast cancers are found in women over age 50. - Family history of breast cancer in mother or sister. - Having the BRCA1 and BRCA2 genes. Women with these genes account for 5 to 10% of cases of breast shemagh cancer and have a 80% chance of developing breast cancer at some time in h
