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.
背景
戒烟是吸烟者预防癌症的关键行为；尽管如此，吸烟者仍能从癌症的早期诊断中获益。然而，尽管吸烟者患癌风险增加，但参与筛查的人数较少，这可能反映了他们对癌症的不同看法。
方法
使用癌症认知与信念量表对英国⩾50岁的具有代表性的样本（n = 6965）进行了调查。这些分析考察了关于癌症信念的六个项目（例如，“癌症通常可以治愈”），以及关于寻求帮助障碍的四个项目（例如，“我会太尴尬”）。
结果
在六个项目中的四个项目上，吸烟者比从不吸烟者或曾经吸烟者更倾向于持有悲观的癌症信念。例如，34%的人同意“癌症诊断等同于死刑判决”，而非吸烟者/曾经吸烟者中这一比例为24%（P < 0.001）。与非吸烟者/曾经吸烟者（11%）相比，更多吸烟者（18%）不想知道自己是否患有癌症（P < 0.01）。因吸烟状况不同而存在差异的寻求症状性帮助的唯一障碍是“担心医生可能发现的情况”（36%对28%，P < 0.01）。这些关联独立于人口统计学特征、自我评估的健康状况和癌症经历。
结论
吸烟者对癌症持有更悲观和回避的信念，这可能会阻碍早期检测行为。需要更好地理解这些信念，以提高这一高危群体对早期诊断的参与度。
