Abnormal development of cells leads to the growth of tumor, when tumor is malignant in nature they are termed as cancer. Breast cancer is the most common type of cancer diagnosed in women today. Around the world breast cancer statistics shows that after lung cancer breast cancer is the second most death-causing factor in people who develops cancer. The risk factor of developing breast cancer increases with the age, it does not only relate to women, figures show that out of every 100 women there is one male who is diagnosed of breast cancer.
Breast cancer does not mean a specific category of disease rather it is the different types of cancer generally found in breast is collectively termed as breast cancer. Though the most common understanding suggests that, abnormal growth of cells in the breast causes breast cancer.
Breast Cancer Symptoms
Early breast cancer has no symptoms. It is usually not painful.
Most breast cancer is discovered before symptoms are present, either by finding an abnormality on mammography or feeling a breast lump. A lump in the armpit or above the collarbone that does not go away may be a sign of cancer. Other possible symptoms are breast discharge, nipple inversion, or changes in the skin overlying the breast.
Most breast lumps are not cancerous. All breast lumps, however, need to be evaluated by a doctor.
Breast discharge is a common problem and is rarely a symptom of cancer. Discharge is most concerning if it is from only one breast or if it is bloody. In any case, all breast discharge should be evaluated.
Nipple inversion is a common variant of normal nipples, but nipple inversion that is a new development can be of concern.
Changes in the skin of the breast include redness, changes in texture, and puckering. These changes are usually caused by skin diseases but occasionally can be associated with breast cancer.
Causes of Breast Cancer:
Breast cancer is the most common cause of cancer in women and the second most common cause of cancer death in women in the U.S. While the majority of new breast cancers are diagnosed as a result of an abnormality seen on a mammogram, a lump, or change in consistency of the breast tissue can also be a warning sign of the disease. Heightened awareness of breast cancer risk in the past decades has led to an increase in the number of women undergoing mammography for screening, leading to detection of cancers in earlier stages and a resultant improvement in survival rates. Still, breast cancer is the most common cause of death in women between 45-55 years of age. Although breast cancer in women is a common form of cancer, male breast cancer does occur and accounts for about 1% of all cancer deaths in men.
Research has yielded much information about the causes of breast cancers, and it is now believed that genetic and/or hormonal factors are the primary risk factors for breast cancer. Staging systems have been developed …
