Cervical Cancer

SER-vih-kul KAN-sernoun phrase

A cancer that begins in the cervix, the lower part of the uterus, and is among the most preventable cancers.

Cervical cancer develops in the cells of the cervix, the narrow lower end of the uterus that opens into the vagina. It is most often caused by long-lasting infection with certain types of human papillomavirus. Because it usually develops slowly from detectable changes, regular screening makes it one of the most preventable cancers.

What is cervical cancer?

Cervical cancer begins in the cervix, the lower, narrow portion of the uterus that connects to the vagina. It usually develops gradually. Long before cancer appears, the cells of the cervix can go through abnormal changes, sometimes called dysplasia, that may progress over years if not found and addressed. This slow, stepwise process is exactly what makes cervical cancer so well suited to early detection.

The single most important cause is persistent infection with high-risk types of human papillomavirus, or HPV, a very common virus passed through intimate contact. In most people the immune system clears HPV on its own, but when certain types linger, they can drive the cellular changes that lead toward cancer. Vaccines that protect against the highest-risk HPV types have made it possible to prevent many of these infections in the first place.

Screening is the other powerful tool. A Pap smear collects cells from the cervix to look for early changes, and HPV testing can identify the virus types most likely to cause trouble. If something abnormal turns up, a closer examination called colposcopy, sometimes with a small biopsy, can clarify what is happening. When changes are found early, they can often be treated before they ever become cancer, and when cancer is found, staging helps guide the path forward. A health professional can explain which screening schedule fits your age and history.

Why it matters

Cervical cancer is one of the few cancers that is highly preventable, and that is genuinely hopeful news. Through HPV vaccination and regular screening with Pap smears and HPV tests, abnormal changes can be caught and treated long before they would ever become cancer. Many cases could be avoided entirely.

This is why staying current with screening matters so much, even when you feel completely well. Early cervical changes cause no symptoms, so they are found by looking, not by waiting for something to feel wrong. Understanding the link between HPV, screening, and prevention puts a remarkable amount of protection within your reach, supported by your care team.
