Knowledge of risk factors in cancer

摘要

Many modifiable risk factors for cancer have been reported, including: smoking, estimated to cause one-third of UK cancers;1 obesity; low intake of fruit and vegetables, and physical inactivity, estimated to cause approximately 3% and 2% of cancers respectively;2 excessive alcohol use, accounting for about 4% of cancers, and excess exposure to sunlight. Public knowledge of these risk factors is little known, as surveys have generally concentrated on specific cancers;3,4 or been relatively small.
