There is one ethnic group where penile cancer is extremely rare and the incidence of cervical cancer is also very low. Not because they are physically superior to other ethnic groups, but because this ethnic group practices “circumcision” on the eighth day after the birth of a boy, so there is almost no occurrence of penile cancer. Similarly, Muslim Muslims have a similar circumcision practice, but they circumcise their boys between the ages of 4 and 10, and studies have found that their incidence of penile cancer is also very low. Studies in India, for example, show that Hindus account for 97.5% of penile cancer patients, while Islamists account for only 2%. And the reason why this ethnic group has a lower incidence rate than the Islamists is the Jewish ethnic group is because they cut so many years earlier than the Islamists. So why are Jews less likely to get penile and cervical cancer? Some may question, is this true? Indeed, studies have found that penile cancer is closely related to prepuce and circumcision, and prepuce and circumcision are the main high-risk factors for the occurrence of penile cancer, and almost all penile cancer patients have prepuce or circumcision. Almost all patients with penile cancer are circumcised or circumcised. And adult circumcision cannot reduce the incidence of penile cancer, which is the reason why Jews are less likely to get penile cancer. In addition, male circumcision protects women from cervical cancer – an opinion based on extensive research. Some clinical data point out that human circumcision has a decisive influence not only on the development of penile cancer, but also has a close relationship with the development of cervical cancer. Circumcision may be a carrier of HPV virus or chemical carcinogens. Some foreigners have successfully induced cervical cancer in mice with human circumcision. Domestic studies have also confirmed the carcinogenic effect of human prototype circumcision or total lipid of circumcision on both cervical and vaginal epithelium in mice. It is now believed that the cholesterol in foreskin wax can be transformed into carcinogenic substances by bacterial action. The incidence of cervical cancer in Jewish women is very low, with foreign scholars reporting that Jews account for only 25 of the 1,342 cases of cervical cancer. This phenomenon has been attributed to the widespread practice of male circumcision among Jews. In addition, the incidence of female cervical cancer among indigenous Fijians and Hindu immigrants, despite living together in one country, is much lower in the former than in the latter, which is also attributed to male circumcision. Early studies determined that there was only one reason for the difference in cervical cancer rates – and that was that Fijian men are circumcised, while Hindu immigrant men are not. Other studies comparing the incidence of cervical cancer in Hindu and Muslim women living together in India have found that the incidence is also higher in the former, again proving that the difference is due to the fact that Muslim men are circumcised and Hindu men are not. In addition to circumcision, the low incidence of cervical cancer in Jewish women is also strongly related to religious factors. Because of their strict adherence to the rules of sexuality set forth by religious law, Orthodox Jewish adolescent girls are less likely to have sex with men and do not have as many sexual partners as women who are not bound by religious beliefs. These reduce the risk factors for contracting cervical cancer.
