Not sure to be worried or not

I found a lump the 12th of February this year, I was told by a doctor it as a blocked duct (as is be to young to get breast cancer) I was given anti inflammatories and told to come back on the 12th of March, because every lump has to be checked no matter what it is..
I went back the 12th of March, it was a different lady doctor who checked this time, she wrote up a referral for Galway straight after she had checked my breasts,
She had told me the inflammation was gone and the lump was still there,
I wasn't told much else only to wait for my Galway appointment and go from there
My symptoms fairly added up as I have experienced quite a few of the symptoms of Breast cancer

Should I be worried or not considering I'm only 19 should breast cancer be a possible outcome for me or not?
