Cervical cancer happens when the immune system can’t clear high-risk strains of HPV.

Over time, these cells can turnprecancerous, then cancerous.

Routine Pap screening can allow healthcare providers to detect and remove precancerous cells before they become cancerous.

Vaccines won’t help if you’re already infected.

Summary

HPV is the most common STI.

It spreads so easily that just about every sexually active person gets it at some point.

Most of the time, the immune system can scrub the infection without symptoms or complications.

However, some low-risk strains can cause troublesome warts.

HPV vaccines effectively prevent the strains most likely to cause warts and cancer.

There are no HPV tests for men, but women can get tested along with a Pap test.

Speak to a healthcare provider if you think you may have HPV or have screening questions.
