Cervical cancer

firstly hi yesterday I was was diagnosed with cervical cancer I had an mri and got the results that it’s more than likely that.  I have been having abnormal smears around 2 years I’ve had 2 letz procedures the latest been December 2018 which came back no pre cancerous cells detected repeat smear in 6 months which I had on 10th July (still awaiting the results).  I don’t understand how that can have come back clear but the mri detects it.  I am petrified I’m going to die I’m a single Mum if a 15 year old boy.  Has anyone else been through the same circumstance.  I go see the consultant at 1 today to discuss the findings.
