Hi,
There is no conclusive evidence to suggest that 
Microgynon 30 causes cervical erosion. Cervical erosion, also known as 
cervical ectropion or cervical eversion, is a common condition that occurs when the lining of the 
cervix protrudes onto the outer surface of the cervix. While the exact cause of cervical erosion is unknown, it is thought to be linked to 
hormonal changes, infection, or injury to the cervix.
Stopping the use of Microgynon 30 may help to reduce the incidence of cervical erosion by decreasing the amount of hormonal influence on the cervix, but it is not a guaranteed solution. However, it is important to note that cervical erosion can have various causes, and stopping the use of Microgynon 30 may not address the underlying cause of the condition.
It is advisable to consult with your healthcare provider for a thorough evaluation and personalized recommendations regarding your 
contraceptive options and management of cervical erosion.
Take care. Hope I have answered your question. Let me know if I can assist you further.
