Tumor prevention and control can only be truly preventive if it is incorporated into people’s daily life and work agendas. The ultimate goal of cancer prevention is to reduce the incidence of cancer and mortality. Primary prevention Its goal is to prevent the occurrence of cancer and reduce the incidence rate.
