What causes cervical dysplasia?

HPV can alter cells on the cervix. In many people the immune system clears the infection, but when a high-risk type remains, abnormal cells may develop. Smoking and a weakened immune system can make persistent infection or cell changes more likely.

Dysplasia means that cells on the surface of the cervix look abnormal; it is not the same as cervical cancer. Reports may call it cervical intraepithelial neoplasia, or CIN, and describe how extensive the changes are. Cervical dysplasia often causes no symptoms and is commonly found through cervical screening.

An HPV result cannot show when the infection was acquired or from whom. HPV may remain undetected for a long time, so a positive result does not establish recent transmission or infidelity.

Follow the timing in your screening report or clinician's plan. Depending on the cell changes and HPV result, the next step may be repeat testing, colposcopy to examine the cervix closely, or a biopsy. Some changes can be monitored, while more significant changes may be removed to prevent progression.

Keep every follow-up appointment even if you feel well. If you smoke, ask for practical support to stop, and tell the clinician about medicines or conditions that suppress your immune system because these details can affect follow-up planning.

Arrange a medical assessment for bleeding between periods, bleeding after sex, bleeding after menopause, unusual vaginal discharge, or ongoing pelvic pain. Cervical dysplasia itself commonly has no symptoms, so these changes need evaluation for other possible causes rather than waiting for the next routine screen.

Seek urgent care for very heavy bleeding, fainting, severe or rapidly worsening pelvic pain, or fever with feeling seriously unwell. If you are pregnant and bleeding, contact your maternity service promptly for guidance.

Ask what grade of cell change was found, whether high-risk HPV was detected, and whether you need repeat testing, colposcopy, or treatment. You can also ask how the proposed plan could affect future pregnancy, what symptoms after a procedure require attention, and how results will be communicated.
