Again, with better methods of diagnosis (诊断), doctors can more easily recognize cancerous growths that would formerly have pasd unnoticed or that would have been wrongly diagnod. It is also believed that certain habits and conditions of modem living, including heavy smoking and the pollution of the air, may leave people living in more cancer-causing conditions than before.
