Hi,

I just wanted some advice really. As I don't want to waste medical time or appointments. 
last year may 2019 I had a core biopsy, as I foun a lump in my left breast. Thankfully this turned out to be fibroidenomatoid.

however this year March 2020 I found my left lymph node (axillary area) was swollen. I spoke to the doctor and she confirmed I did have a lump but didn't want to do further tests as of yet as covid was at its "peak". However I have also noticed it changes the week of my period, it goes down in size, but as soon as my period is over, increases in size again. 

I am only 23, I have 2 children, so I worry for their sake. The chances of it being sinister is extremely unlikely due to my age.
But I just wanted to know if anyone has experienced lymph node changes, and what is best to do really.
