Reoccurring candida infection & intense burning in chest/oesphagus caused by breast cancer chemo (EC) - only option suggested to scale back chemo?

Hello, 

I'm hoping someone may be able to help or perhaps identify with this if you've encountered a similar situation...although Ive been told its unusual!

I'm currently undergoing chemo (EC-T) for breast cancer (following a masectomy for local spread of BC with 1 lymph node involved) and have encountered a real issue with oral thrush/candida (& potentially oesophageal candida too - as the burning in my chest has been horrendous - this has been the main area of concern).

Due to the fungal/thrush/Candida infection that the chemo causes, Ive been too unwell to proceed with chemo (so dose and duration of chemo cycles have already been reduced) & its taken weeks of flucanazole treatment (at increasingly high doses) to try and get back to a point where I am well enough to proceed with chemo.

I just wondered has anyone ever encountered a similar issue please? Where candida infections have been ongoing and its been really problematic in terms of chemo? 

At present the main suggestions from my treatment team are to reduce the chemo again (number of cycles and dose). I just wondered if anyone has been able to navigate this more successfully - so that you can proceed with chemo without the risk of a severe fungal infection escalating?

(Unfortunately they haven't been able to determine much about the type of candida infection I've had to date as I was prescribed fluconazole before any oral swabs were taken, so the swabs, after taking fluconazole, just come back with no result). 

Thank you x
