The European Code against Cancer recommends not to smoke, to avoid alcohol consumption, to eat a healthy diet, and maintain a healthy weight to prevent cancer. To what extent is the public aware of the influence of these lifestyle factors on cancer development? The goal of the current study was to describe the perceived influence of four lifestyle factors (tobacco, alcohol, diet, and weight) on cancer development in the general population and identify factors related to low perceptions of influence. We analyzed data from the 2020 Onco-barometer (n = 4769), a representative population-based survey conducted in Spain. With the exception of smoking, lifestyle factors were among those with the least perceived influence, more so among the demographic groups at higher risk from cancer including men and older individuals (65+ years). Individuals from lower socio-economic groups were more likely to report not knowing what influence lifestyle factors have on cancer. Lower perceived influence was also consistently related to perceiving very low risk from cancer. Overall, although there is variation in perceptions regarding the different lifestyle factors, low perceived influence clusters among those at higher risk for cancer. These results signal the need for public health campaigns and messages informing the public about the preventive potential of lifestyle factors beyond avoiding tobacco consumption.

OBJECTIVE: Implementation of Shared Decision Making (SDM) in oncology is limited. The objective of the study was to determine the extent of physicians' awareness of Shared Decision Making (SDM) in their treatment of cancer patients, the usefulness that they assign to SDM, the role they play, their assessment of SDM, and perceptions of the main barriers and facilitators to its use. METHODS: A questionnaire was completed by medical oncologists, radiation oncologists and general surgeons working in Andalusia (Spain). Sociodemographic, clinical-care and aspects of SDM variables were collected. SDM was evaluated using the SDM-Q-Doc questionnaire. Non-parametric contrasts were used to determine the possible differences between medical specialties. RESULTS: The questionnaire was sent to 351 physicians. The response rate was 37.04%, 63 women and 67 men, with an average age of 45.6 years and 18.04 years' experience. Of these, 33.08% were medical oncologists, 34.61% radiation oncologists and 29.23% general surgeons. A total of 82.3% stated they had received no training in SDM, whereas 33.8% said they knew a lot about SDM and applied it in practice; 80% considered it to be very useful. In addition, 60% of respondents said they were mainly the ones who made the decisions on treatment. An evaluation of SDM on the SDM-Q-Doc scale showed that all the specialities scored more than 80/100. The main barriers to applying SDM were the difficulty patients experienced in understanding what they needed to know, the lack of decision aids and time. CONCLUSIONS: Some 82% of physicians have no training in SDM and 66% don´t use it in practice, with decisions on treatment taken mainly by the physicians themselves. Strategies to increase training in SDM and to implement it into clinical practice are important.
