About Breast Cancer

In a healthy body, natural systems control the creation, growth and death of cells. But when these systems malfunction, more cell growth than death can occur. The result is a mass of tissue we call a malignant tumor—or cancer. And when this process takes place in the breast, it’s breast cancer. Tumors in the breast tend to grow slowly; by the time a lump is large enough to feel, it may have been growing for as long as 10 years. Some tumors, however, are aggressive and grow much faster.

But there is hope. Thanks to heightened awareness, early detection through screening, improved treatment methods and increased access to breast health services, people have a greater chance of survival than ever before.
