Xanthelasma and raised cholesterol on letrozole.

Triple pos IDC girl here. I’m post 5 mths chemo, single mastectomy with lymph sweep with clear margins and post oopherectomy.  Finished trastuzimab a bit early due to side effects so now plan is for just hormone therapy 5 yrs.

 I just saw GP today regarding what looks like xanthelomas.  Hes given me blood form to check cholesterol and thyroid.  

I showed oncologist yellow skin 2 mths ago and again 5 days ago and she saying it’s not related to any cancer treatment and see GP.  I looked up Letrozole info on eviQ and it states that raised cholesterol a known side effect and that levels will be monitored.  Today I’ve just got results back and LDL is 5.9 and total cholesterol is 8.2. I’m starting to lose trust in oncologist and feel like I’ve got to check everything so to prevent medical harm. I do t have medical training but do have a keen interest in reading full info of every medical intervention due to previous experiences with medical system.

Anyone else have cholesterol issue on letrozole? And if so did you switch to diff AI? Or did you stop taking? Or did you treat naturally?  EviQ says other AI’s can all raise cholesterol too.
