Lip cancer: incidence, trends, histology and survival: 1970-2006

Abstract

Men, fair-skinned individuals and those over 53 years of age were at higher risk for lip cancer. A higher incidence of external lip cancer, compared with internal, may indicate a major role for sun exposure rather than smoking. The effect of public awareness campaigns as well as occupational changes, both related to sun exposure, should be studied carefully as potential factors in the changing incidence of lip tumours.
