Abstract
To calculate the probability of one person's life-time death caused by a malignant tumor and provide theoretical basis for cancer prevention. The probability of one person's death caused by a tumor was calculated by a probability additive formula and based on an abridged life table. All data for age-specific mortality were from the third retrospective investigation of death cause in China. The probability of one person's death caused by malignant tumor was 18.7% calculated by the probability additive formula. On the same way, the life-time death probability caused by lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal and anal cancer were 4.47%, 3.62%, 3.25%, 2.25%, 1.11%, respectively. Malignant tumor is still the main cause of death in one's life time and the most common causes of cancer death were lung, gastric, liver, esophageal, colorectal and anal cancers. Targeted forms of cancer prevention and treatment strategies should be worked out to improve people's health and prolong life in China. The probability additive formula is a more scientific and objective method to calculate the probability of one person's life-time death than cumulative death probability .
Highlights
Materials and MethodsThere are at least two methods used to find the probability of death by cancer: the one is cumulative death probability (Sun, 2008), the other one is probability additive formula (Zhang, 2010)
By using probability additive formula and based on abridge life table (Sun et al, 2006) we found one person’s life-time death probability caused by malignant tumor in China is 18.73%, which was different from 13% calculated by cumulative death probability, published by 2012 Chinese Cancer Registry Annual Report

Summary
Materials and MethodsThere are at least two methods used to find the probability of death by cancer: the one is cumulative death probability (Sun, 2008), the other one is probability additive formula (Zhang, 2010). The 2012 Chinese Cancer Registry Annual Report, published by the National Cancer Registry, pointed out that the probability of one person’s life-time death caused by malignant tumor was 13% in China (Inoue et al, 2000; Hao et al, 2012), which was calculated based on a cumulative death probability from 0-74-year-old residents. It does not including a person’s whole life time, as someone maybe lived more than 74 year old and it does not consider the risk of death competition. The aim of this study is to calculate the probability of life time death caused by a malignant tumor by probability additive formula
