Despite having a FDR diagnosed with bowel cancer only 36% of participants reported being asked about family history of CRC by a health professional. These results are in line with a recent study by Courtney et al. [7] of community-dwelling adults aged 50 and older, which found that 38% had been asked about family history by a health professional. Previous research has shown that doctor endorsement is a key factor in promoting screening participation

[12], [16] and [17]. Therefore, the low rates of recall of doctor discussion identified in this study are of concern. Those aged 50–60 were more likely than younger participants to have discussed family history with their doctor. This may reflect that current screening NLG919 concentration guidelines recommend population screening for CRC commence at age 50. Therefore, some participants in this age group should have been contacted by the National Bowel Cancer Screening Program and Fluorouracil price may have discussed the invitation with their doctor, or may have had their doctor proactively initiate discussion of CRC screening given that they are at the appropriate age for screening. Those at highest risk of CRC were also more likely than other respondents to have had a discussion about family history. A study by Honda and Neugut [18] demonstrated that perceived risk may be a dose-response relationship, i.e., the greater

number of family members affected, the greater the perceived risk. Therefore it is likely that those at highest risk who may have several relatives affected by CRC are more aware of their risk, and have potentially been exposed to triggers to discuss this with a health professional. As found in other studies [13] level of education was also associated with discussing family cancer history with a doctor. Over half of the participants knew about increased risk associated with family history due to a family member being diagnosed with CRC. This is similar to the findings of Lim

et al. [12] that family cancer events and reaching the age at which relatives were diagnosed with cancer had a bigger impact in raising the awareness of the risk due to family history than the media and publicity. This is likely due to the feelings of personal susceptibility that a family Adenosine cancer event may evoke. Nevertheless, media campaigns have been shown to be effective in increasing awareness of and promoting uptake of health behaviours in relation to some screening behaviours [19] and [20], and hence, the potential role of the media in relation to awareness of the risks conferred by family history of CRC should be further explored. One of the strengths of the current study was the attempt to gain a population perspective by contacting all eligible ICs identified through a population-based cancer registry, and subsequently contacting the FDRs of consenting ICs.
