title: [Cancer prevention].
abstract: The 12 th Oncology Forum discussed the progress and future strategy of cancer prevention in Japan. The National Cancer Center has established a research center for screening focusing on the most common six cancer, stomach, lung, liver, colon, breast and uterus cancer. The program so far had a cumulative detection rate of 3.3%, which is high,and may reflect the selection of subjects. Screening and chemoprevention is also being investigated in prostate cancer, but the issues centre on how to make this widely available. High risk subjects can also be identified for breast cancer. Obesity and family history are especially important. In colorectal cancer studies are evaluating different diets, but general application is not yet possible and the infrastructure to implement any general screening and prevention does not exist. Development of pharmaceutical treatments for prevention is difficult because of the need for very safe treatments, and also because of the length of time needed to carry out studies. Overall, cancer prevention is still in evolution. New approaches are needed, and new infrastructure will be needed at a government level to implement this.
