What Stage IA1 Means
Invasive cancer <3 mm depth, <7 mm width; confined to cervix
Treatment Approach for Stage IA1
Conization (cold knife, laser, or loop electrosurgical excision [LEEP]) with negative margins; simple hysterectomy if completed childbearing; fertility-sparing options available
Survival Rates and Prognosis
The 5-year survival rate for cervical cancer at Stage IA1 is approximately 95–98%. Survival rates are statistical averages drawn from large patient populations and may not reflect your individual outcome. Factors that influence your specific prognosis include your age, overall health, tumour biology, and how well the cancer responds to treatment.
Important: These numbers are drawn from historical data. Newer treatments available today may improve outcomes beyond what published statistics show. Discuss your individual prognosis with your oncologist.
