Shapes of statistical graphs reveal important information on cancer biology
 which is generally ignored. This and the forthcoming presentations will provide a new interpretation  of these shapes.

The study observes a group of patients diagnosed at the age of 50-59y.
They were followed for 15 years, until reaching the ages 65-74y.
The mean hazard rate of these women declines with time indicating that their prospects improves.
   The improving prospect of women with breast cancer does not imply that they will be cured, but that  their  life with cancer will improve. The longer they live the better their chance to survive.

If their  chances improve, why do they die?

Since cancer is a triad consisting of
1 Treatable tumor
2  Untreatable paraneoplasia -  .
3  Untreatable cachexia
