Formation of abnormal cells, which grow to form more new cells that are not required for functional growth processes can lead to the formation of a mass growth which is called a tumor. Cancer of the breast results from the growth of malignant tumors in the glandular tissues of the breast. Today, more women are surviving breast cancer than ever before. Well over 2 million women have been recorded to have survived breast cancer. With early detection and prompt appropriate treatment, the outlook for women with breast cancer is typically positive.
It is still not clear why a certain group of women develop breast cancer though others usually do not. Although the disease may be seen to affect younger women, 75% of most breast cancer cases have been reported to occur in women over the age of 50. Some of the noted risks factors include exposure to estrogen, familial or genetic predisposition, issues related to demographics (age, race, ethnicity, and socioeconomic status), lifestyle, nutrition and smoking.
Signs of breast cancer are hardly apparent during the developing stages. As the cancer grows, it may lead to obvious changes that women need to watch for. The most common symptoms are abnormal lumps, swelling in the breast, or lumps that appear near the breast or under arm. Other symptoms that could indicate the presence of breast cancer may include unusual pain around the nipple, abnormal discharge from the nipple, obvious changes in the texture of the breast, or changes in the skin around the breast.
