This study assessed the level of knowledge of a representative sample of the Maltese male population on TC and TSE, and the association between various demographic factors and knowledge and practice of TSE. The study also explored men’s willingness to learn about and perform TSE as well as their suggestions for how such information can be provided.
The majority of participants were aware that swelling or a lump is a symptom of TC but knowledge of other TC symptoms was variable. In addition, knowledge of the relationship between age and incidence of TC was variable. Most of the participants believed that TC can be cured.
When asked about TSE, most participants were ready to perform it on a regular basis, although less than half knew that TSE should be performed once a month. More than half of the respondents had never performed TSE and the main reason for this was due to lack of knowledge about how to do a self-examination. This is not surprising as a very small number of participants (approx. 10%) have been shown by a doctor how to perform TSE.
The results also show that people in employment, students and those with higher income have better knowledge of TSE. There were significant associations between knowledge of TSE higher level of education, younger age and history of TC in the family. There were also significant associations between practice of TSE and knowledge of TSE and history of TC in the family.
Finally, almost all of the respondents deemed the need for public information on TC as important, with the majority of these suggesting the use of a media or social media campaign.
The variable knowledge of TC symptoms in the current sample is not surprising, as lack of knowledge of TC symptoms among men in the general population has been highlighted before [23, 32, 37]. However, the fact that most participants correctly identified that difference between testicles like presence of lump or swelling in one testicle as a sign of potential TC shows that men are aware of an important TC symptom and suggests the need for more education about other symptoms of TC. Moore and Topping [24] reported similar results with 74% of participants correctly indicating that lumps were associated with TC. Similarly to previous research, the men in this study correctly answered that if TC is treated at an early stage it can be cured [48].
This study found an association between knowledge of TSE and actual performance of TSE, which is consistent with previous research [22, 37]. The majority of men in this study were willing to perform TSE on a regular basis but more than half had never done it before and reported lack of knowledge on how to do TSE. These results are consistent with previous literature, which shows low knowledge of TSE amongst males [23, 35, 37, 48–52]. The fact that approximately 10% of the men in the current study were shown by a doctor how to perform TSE indicates a serious gap in a potential source of education on TSE. This has also been identified in other studies [33, 37, 53, 54]. One reason for this could be that TC awareness training is not promoted during Medical, Nursing, or health visitors training who all can play a key role in this regard [53, 55–57]. Brenner et al. [54] also reported that fewer than half of the pediatric residents educate patients on TSE since they believe it can cause excess anxiety. Increased TSE awareness training for physicians, nurses, GPs and public health officers has been shown to decrease delay in the diagnosis of TC and improve disease-free survival [17, 52, 56, 58]. This is important because physician recommendation on TSE practice has been found to have striking success, with men who reported a physician recommendation for TSE having at least six times higher odds of performing regular TSE compared with those who reported no such recommendation [59].
The current study found that younger people (16–45 years old), and those with higher level of education and income have better knowledge of TSE. The fact that younger people within the risk age of 16–45 years old have better knowledge of how to carry out a TSE is encouraging. However, this still indicates that a substantial number of respondents within the risk age bracket are still uninformed about TSE. Similar findings in relation to age, education and income have been reported before [17, 23, 48, 60, 61].
Finally, it was revealed that almost all of the respondents deemed the need for public information on TC and TSE as important. Other studies also found such high interest of respondents in accessing information and to perform TSE on a regular basis [14, 22, 24, 62]. These findings suggest that males within the risk age bracket may be open to receiving information and at least contemplate performing TSE regularly. Consequently, a campaign or educational interventions targeted at this age group may deliver positive results.
Existing controversy about the effectiveness of TSE awareness programs needs to be mentioned [63–65] although most studies have exhibited positive changes [23, 29, 50, 59, 66]. Promotion of TSE and public education should remain important initiatives [45, 67, 68].
With reference to the type of ideal approaches for educational campaigns, the majority of participants in the current study suggested either a media or social media campaign. The finding related to social media is congruent with previous research [34, 48, 56]. Online education can include slide shows as available at Teens Health [69]. Individualized, tailored messages rather than group sessions have been suggested [22]. Educational brochures have been shown to lead to more positive beliefs about practical and health consequences and more positive TSE attitude and intention [26]. Cox et al.’s [70] multimedia approach to TSE training and reminding system, cuing and active modeling can present a comprehensive approach to increasing TSE regular performance among at-risk males. Mechanisms to remind males to perform TSE may potentially produce positive, sustainable health behavior choices [22].
Healthcare professionals are in an excellent position to deliver education interventions. Young men attending healthcare institutions can be given health education on TSE, perhaps accompanied by a patient leaflet. Such teaching could be incorporated into routine outpatient and inpatient interactions with high risk clients [37, 51]. In USA, males beginning at the age of 15 years are ideally provided with the knowledge to practice TSE by physicians or nurses [51, 60, 71]. Cancer registries and support groups in the United Kingdom also recommend that young men should be provided with information on basic awareness of TC and when to seek medical advice [48, 51].
Reference has likewise been made to the importance of raising awareness of both TC and TSE screening using early educational interactive sessions as a subject integrated within school subjects for boys and young men who are at highest risk [23, 35, 60, 72]. Teachers in schools could organize seminars and conferences to inform students on the importance and practice of TSE [72]. Policy makers should consider the introduction of TSE education sessions in secondary school curricula [51, 73]. Screening clinics at sports clubs and gymnasiums can also offer an opportunity to increase awareness of TC and TSE [74].
Implications For Practice
The results from the current study have a number of implications and recommendations for public health practice:
-
Creating effective National Public Awareness Campaigns, interactive social media and internet tools to educate young people who are most at risk.
-
Develop audiovisuals and pamphlets as supportive materials.
-
More training for healthcare professionals, including physicians, GPs and nurses to realize their important role in educating young people on TC and to encourage performance of TSE.
-
Developing TC and TSE awareness educational programs as part of School Health curricula that includes health belief scale assessment to do TSE following information provision. This could be done by trained school nurses, teachers or physical education instructors.
-
Fitness centers and gyms could be other potential educational centres.
-
Pre-post testing of all educational campaigns initiatives implemented should be a routine procedure to ensure that the audit cycle process is closed.
-
It is recommended that future studies include studies to identify GPs and health centers physicians’ awareness of how to do TSE and if they are educating young persons.
-
Studies specifically targeting populations for at-risk age bracket of 16–45 years will provide a more focused target population.
