Background:
Smoking cessation is the key cancer prevention behaviour for smokers; nonetheless, smokers can still benefit from earlier diagnosis of cancer. However, fewer smokers participate in screening despite their increased risk, which may reflect different beliefs about cancer.
Methods:
A UK population-representative sample of ⩾50 year-olds (n=6965) was surveyed using the Awareness and Beliefs about Cancer measure. These analyses examine six items on cancer beliefs (e.g., 'cancer can often be cured'), and four on help-seeking barriers (e.g., 'I would be too embarrassed').
Results:
Smokers were more likely to hold pessimistic cancer beliefs than never-smokers or former-smokers on four of six items. For example, 34% agreed 'a cancer diagnosis is a death sentence', compared with 24% of non/former-smokers (P<0.001). More smokers (18%) than non/former-smokers (11%) would not want to know if they had cancer (P<0.01). The only barrier to symptomatic help-seeking differing by smoking status was 'worry about what the doctor might find' (36% vs 28%, P<0.01). Associations were independent of demographics, self-rated health and cancer experience.
Conclusions:
Smokers held more pessimistic and avoidant beliefs about cancer, which could deter early-detection behaviour. A better understanding of these beliefs is needed to increase engagement in early diagnosis by this high-risk group.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
