It is fairly common for people to be diagnosed with stage 2 breast cancer. Stage 2 tumors are usually between 2 and 5 centimeters cm in diameter 1 to 2. Radiation therapy is given following a lumpectomy, but may or may not be needed after a mastectomy. If the tumor is estrogen receptor-positive, hormonal therapy is usually given for five to 10 years, and for those who are postmenopausal, bisphosphonate therapy may be recommended as well to reduce the risk of recurrence. Stage 2 breast cancer is considered "invasive," meaning that cancer cells have broken out of the ducts or lobules of the breast. This is not the same as metastatic stage 4 breast cancer.

Breast Cancer Research and Treatment provides the surgeon, radiotherapist, medical oncologist, endocrinologist, epidemiologist, immunologist or cell biologist investigating problems in breast cancer a single forum for communication. The journal creates a "market place" for breast cancer topics which cuts across all the usual lines of disciplines, providing a site for presenting pertinent investigations, and for discussing critical questions relevant to the entire field. It seeks to develop a new focus and new perspectives for all those concerned with breast cancer.




The rate of survival among breast cancer patients has increased dramatically in recent decades. This is likely attributed to an improvement in screening and early detection, increased awareness of symptoms, and improvements in treatment options. Due to the decline in death rates, it is estimated , deaths were avoided in the United States between and There are a number of factors that can improve or worsen prognosis. Breast cancer staging is used to classify how far cancer has spread and how much cancer is in the body.
