Guidelines vary slightly by province but are generally recommended for women starting around age 21-25 (or once sexually active) and continuing every 2-3 years if results are normal. The frequency may change based on your age, medical history (including HPV status), and previous Pap test results. Dr. Dervaitis will advise you on the appropriate screening schedule for your individual circumstances based on current provincial guidelines.
