What is a secondary complication that can arise from untreated pelvic inflammatory disease linked to chlamydia?

Ectopic pregnancy is a significant secondary complication that can occur as a result of untreated pelvic inflammatory disease (PID) linked to infections like chlamydia. PID can lead to scarring and damage within the fallopian tubes, which impairs the normal passage of a fertilized egg to the uterus. When an egg is unable to move through the fallopian tubes correctly, it may implant and begin to grow there, resulting in an ectopic pregnancy. This condition can have serious consequences for the health of the woman, including potential rupture of the fallopian tube and life-threatening internal bleeding.

The other options listed do not directly correlate with a secondary complication resulting specifically from untreated PID due to chlamydia in the same way as ectopic pregnancy. While conditions like uterine, ovarian, or cervical cancer can arise from various risk factors and health issues, they are not considered immediate or direct complications of PID, especially in the context of chlamydia infection.
