Brachytherapy is a crucial treatment, that significantly contributes to the effective cure of cervical cancer patients. However, traditional survival methods are unable to deal with unobserved cure patients in the censored data. These traditional methods assume those who are censored have the same prognosis as those who remain under observation.

The mixture cure model is specifically developed to handle the challenges. In the mixture cure model, a portion of the subjects are deemed immune from the outcome of interest $(1-\pi(z))$; the outcome of these subjects will never be observed no matter how long the follow-up time is.

$$ S(t|z,x) = 1-\pi(z)+\pi(z)S_{\mu}(t|x) $$

Chinese youth have become more sexually active over the years with rapid modernization and improving gender equity.
