The female breast is composed of skin, fibrous tissue, mammary glands and fat. Breast cancer is a malignant tumor that occurs in the glandular epithelial tissue of the breast. Breast cancer occurs in 99% of women and only 1% of men.
Breast cancer in situ is not fatal because it is not a vital organ that sustains the body’s life activities; however, because breast cancer cells lose the characteristics of normal cells, they are loosely connected to each other and can be easily shed. Once the cancer cells are shed, the free cancer cells can spread throughout the body with blood or lymphatic fluid, forming metastasis and endangering life. Currently, breast cancer has become a common tumor threatening women’s physical and mental health.
The global incidence of breast cancer has been on the rise since the late 1970s. One out of eight women in the United States will develop breast cancer in their lifetime. China is not a country with high incidence of breast cancer, but it should not be optimistic. In recent years, the incidence rate of breast cancer in China has been increasing at a rate 1 to 2 percentage points higher than that of countries with high incidence. According to the data of breast cancer incidence in 2009 released by National Cancer Center and Bureau of Disease Prevention and Control of Ministry of Health in 2012, the incidence rate of breast cancer in the national tumor registration area is ranked the 1st among female malignant tumors, and the incidence rate (crude rate) of female breast cancer is 42.55/100,000 nationwide combined, 51.91/100,000 in urban area and 23.12/100,000 in rural area.
