How is Uterine Cancer Caused?

Question

A 93-year-old patient with poor mental condition wants to know how uterine cancer is caused?

The causes of uterine cancer primarily include the following factors:

Sexual Life: Uterine cancer is closely related to sexual life, with most patients being unmarried women, while married patients are very few. Women who have early sexual activity or early childbirth have a higher incidence of uterine cancer.
Prepuce Smegma Factor: Human prepuce smegma not only affects penile cancer but is also related to the occurrence of uterine cancer.
Viral Infection Factor: Human papillomavirus (HPV) infection is associated with uterine cancer. HPV-specific antigen testing can confirm the association between uterine cancer and HPV infection.
