Alan Walker
Considering what is known about the causes and risk factors for common cancers and then assessing how simple or complex it is to eliminate or modify them in ways that might reduce cancer occurrence are two obvious ways to find chances for cancer control. The potential lay in how simple or complex it is to "treat" those who get cancer or to care for those with cancer who cannot be cured in cases where the causes or risk factors are poorly known, weak, or easily changeable.
