Cancer can also occur in young children and adolescents, but it is rare (about 150 cases per million in the U.S.). Among children, leukemia is the commonest cancer and the next common cancer in children is brain cancers (notably neuroblastoma).
Furthermore around one third of cancers worldwide are due to potentially modifiable risk factors, which are headed by tobacco smoking, alcohol use, and diets low in fruit and vegetables. In addition, being obese and having a sexually transmitted infection are also risk factors for cancers.
