Study Explains Why Smoking and UV Damage Leads to Cancer in Some People

Researchers at the University of Cambridge have published findings that shed light on why DNA damage from sources like smoking and UV radiation causes cancer in certain individuals but not others. The study investigates the biological mechanisms that determine how cells respond to DNA mutations triggered by these common carcinogens. Scientists found that differences in how the body processes or tolerates such damage may explain the varying cancer risk among individuals exposed to the same hazards. The research could have significant implications for understanding personal cancer risk and potentially informing future prevention strategies.
