Human Growth and Development / Unit 13 HGD 1835 short lesson, about 20 seconds
Early-Onset Cancer and Smoking
Captions available
The idea
Early-onset cancers, diagnosed before fifty, such as breast, colorectal and thyroid, are rising; some of the rise reflects more screening.
In practice
Cigarette smoking, the leading cause of preventable disease and death in the United States, accounting for about thirty percent of cancer deaths.
Where people slip
Candidate risk factors for early-onset cancer, including alcohol, obesity and inactivity, are correlational; vaccines prevent HPV- and hepatitis B-linked cancers.
