A Survey on the Knowledge and Awareness of Testicular Cancer and Testicular Self-Examination Among Men in Saudi Arabia

Objectives The aim of the study was to assess the knowledge and awareness of testicular cancer (TC) and testicular selfexamination (TSE) and to identify the associated factors in men in Saudi Arabia. Methods An online questionnaire -based study was conducted in Saudi Arabia with a representative sample of 794 participants. The questionnaire comprised knowledge, awareness and attitude questions regarding TC and TSE in addition to signs/symptoms and risk factors. Multivariate logistic regression analysis was conducted to identify the significant variables associated with knowledge of TC and TSE. Results Around 43% (n=340) of the participants had inadequate knowledge of TC, whereas 26% (n=205) had heard about TSE and only 65 (8.2%) performed TSE. The first model for knowledge found that participants with a low level of education [2.75 (1.18, 6.42)]; no past history of a testicular problem [2.20 (1.22, 3.95)] and those who had not heard about TSE [1.79 (1.24, 2.57)] were at higher odds for inadequate knowledge, whereas those whose mothers had received college -level education [0.39 (0.19, 0.79)] and those who received information from school/college [0.61 (0.37, 0.97)] were more likely to have adequate knowledge about TC. The second model for TSE found that a low level of education 5.24 (1.34, 20.52) was associated with not performing TSE. Receiving information from social media [0.08 (0.03, 0.17)], school/college [0.06 (0.02, 0.13)], family and friends [0.17 (0.05, 0.57)] and medical staff [0.08 (0.03, 0.17)] were associated with higher odds of performing TSE. Conclusion The majority of Saudi males have knowledge about TC. On the contrary, only a small percentage of the respondents have heard of or performed TSE as a screening technique. Educated sources of information can be a reliable way of giving correct knowledge on sensitive topics like TSE.
