Cervical cancer does not develop suddenly. It begins with infection by a high-risk strain of human papillomavirus (HPV), progresses through a series of identifiable precancerous cellular changes (cervical intraepithelial neoplasia, or CIN) over years to more than a decade, and only then — if the precancerous changes are not detected and treated — becomes invasive cancer. This long, identifiable precancerous phase is why cervical cancer is preventable: the screening system is designed precisely to detect and treat it at the CIN stage, before invasion occurs.
The cervical cancer incidence and mortality rates in the United States fell dramatically after widespread Pap testing was introduced — and continue to fall as HPV testing is added to screening protocols and HPV vaccination reaches more of the population. The women most at risk of dying from cervical cancer today are overwhelmingly women whose screening was not current when the disease developed. Staying current with screening is not a formality — it is the intervention itself.
Screening Intervals by Age — Current Guidelines
Under 21: No cervical cancer screening recommended. Cervical cancer is extremely rare in this age group and screening produces more harm from unnecessary evaluation and treatment than benefit. Ages 21 to 29: Pap test (cervical cytology) alone every 3 years. HPV testing is not recommended in this age group because HPV is extremely common and almost always clears without causing significant dysplasia — adding HPV testing would trigger many unnecessary colposcopy referrals. Ages 30 to 65: Preferred approach is Pap test plus HPV co-testing every 5 years. Alternative is Pap test alone every 3 years or HPV primary testing alone every 5 years. Over 65: Screening may be discontinued after adequate prior negative screening history (three consecutive negative Pap tests or two consecutive negative co-tests within the prior 10 years, with the most recent within 5 years). Women with prior high-grade dysplasia continue surveillance for at least 20 years after treatment. Pap vs HPV test explained →
HPV Vaccination — Primary Prevention
The HPV vaccine (Gardasil 9) protects against the nine HPV strains responsible for the majority of cervical cancers, most vulvar and vaginal cancers, most anal cancers, and most genital warts. Vaccination is most effective when given before HPV exposure — ideally in early adolescence. It is routinely recommended at age 11 to 12, with catch-up vaccination through age 26 without shared decision-making, and through age 45 with shared decision-making for adults. Vaccination does not replace cervical cancer screening but adds a powerful layer of primary prevention. Women who were vaccinated in adolescence still require cervical cancer screening at recommended intervals because the vaccine does not cover all oncogenic HPV strains.
The Pathway From Abnormal Result to Treated Dysplasia
When cervical screening identifies an abnormality — an abnormal Pap result or a positive HPV test — the management pathway moves through colposcopy and biopsy to histologic diagnosis and, when indicated, LEEP or cold knife conization. This entire pathway, from screening through treatment and post-treatment surveillance, is managed at Lapeer Women’s Health without referral to an outside clinician. The continuity of care through every step of the cervical cancer prevention pathway is a specific feature of the clinical model at our practice. Full cervical health pathway →
Risk Factors That Increase Cervical Cancer Risk
While virtually all cervical cancer requires persistent high-risk HPV infection, certain factors increase the probability that an HPV infection will persist and progress to dysplasia and cancer: smoking (impairs local cervical immunity and is one of the most modifiable risk factors), immunosuppression from any cause (HIV infection, organ transplant, immunosuppressive medications), failure to maintain current cervical screening, large number of lifetime sexual partners (increases HPV exposure probability), and prior history of high-grade dysplasia or cervical cancer. Smoking cessation is the most important modifiable lifestyle intervention for cervical cancer risk reduction.
Cervical Cancer Symptoms — When to Seek Evaluation Regardless of Screening Status
Early cervical cancer is typically asymptomatic — which is why screening matters. When symptoms develop, the cancer has typically progressed beyond Stage I. Symptoms of cervical cancer include: abnormal vaginal bleeding (between periods, after intercourse, or postmenopausal bleeding), unusual vaginal discharge that is watery, blood-tinged, or foul-smelling, and pelvic pain or pain during intercourse. Any of these symptoms warrants prompt gynecologic evaluation regardless of when the most recent Pap test was performed.
Contact our office promptly if you experience:
- Vaginal bleeding after intercourse (postcoital bleeding) — especially if new or recurrent
- Any vaginal bleeding after menopause
- Unusual vaginal discharge that is watery, bloody, or foul-smelling without an infectious explanation
- Pelvic pain during intercourse that is new or worsening
The data on cervical cancer prevention is clear: women with current screening who develop abnormal results and follow through with evaluation and treatment do not develop invasive cervical cancer in the vast majority of cases. The system works when it is used. The women who develop and die from cervical cancer are overwhelmingly those whose screening lapsed — often for years — during which time the precancerous changes that the system is designed to catch progressed to invasion without detection.
If your cervical cancer screening is overdue — whether by one year or by several — the most important thing is scheduling the visit that gets it current. Dr. Ramona D. Andrei and the team at Lapeer Women’s Health are here for that visit — at both our Lapeer and Rochester Hills offices, without a referral required.
Our team at Lapeer Women’s Health provides cervical cancer screening and complete follow-up at both offices. No referral required.
