Just to clarify since health issues can be such delicate and emotional topics......
Some of you may not be aware that diagnosing cancerous and pre-cancerous cells is my profession. I am not commenting on this thread just to hear myself talk or be critical.
Chrissy, I have every sympathy for your worry and uncertainty. I do think you should see her GP and ask as many questions as it takes for you to be satisfied that you understand your condition.
As a health care professional, I think that practicing medicine is a two way street. Both patients and doctors have responsibilities, and patients need to take the time to inform themselves during the diagnostic and treatment process. Read everything you can about it and write down what you don't understand so you can ask your GP.
I also feel very strongly that the NHS is an overburdened system, and it needs to devote it's resources to the patients who actually need care, not just ones who think they do. If you and your GP decide that it should be removed, then it should be. But I think that is is a decision that can only be made by the two of you, and not based on someone elses advice.
Please ask your GP if the original biopsy was definitive. Sometimes they are not, and if that is the case, the reporting pathologist will have noted that. Otherwise, try to relax and do your homework about your condition. I am always happy to help with definitions/medical terms if you need it. PM me.
