Bi-Modal Hazard (BMH) an epidemiological hallmark of cancer

The phenomenon described by the authors is known as bi-modal hazard rate (BMH).In an detailed analysis based of SEER data I have shown that hazard rate in breast cancer proceeds through three phases. Following diagnosis and treatment hazard rate rises (AB). By the third year it reaches its maximum whereupon it declines to a minimum (BC). from there and on it gradually rises to a second maximum whereupon the patient dies (CD). This pattern appears in many cancers and is unique to cancer and does not appear in other chronic diseases. It is an epidemiological hallmark of cancer. It is so typical of cancer that it distinguishes cancer from other chronic diseases.
