Itchy nipple

Hi I am aware that I am probably over thinking this to much. And I know realistically this forum is for English members and I am from Ireland but it's really just advice I'm looking for

I saw my GP 5 weeks ago as I have this really bad itch around my nipple area for about 3 to 4 months and I am getting recurring sores all around this same breast that are taking months to heal.. so my gp referred me to the breast clinic. I obviously googled and it told me I could be looking at inflammatory breast cancer or pagets if there was anything sinister there. I have very lumpy breasts as well.

Anyway I went to the breast clinic today and when I say I was in and out in 7 mins today I am not exaggerating. He examined my breasts and asked where the lump was and I tried explain that's not why I was there but that I had been told I had lumpy breasts. He paid no attention to the sores on my breast and I tried explain about the itching. He said yes it's hormonal,  I said to him I don't get my period so didn't believe it was hormonal and he handed me a leaflet on breast pain. I said I don't have breast pain it's just itching all around the nipple. And he said no your OK nothing sinister !!! 

How can he tell that without doing any tests. I walked out of his office and burst into tears. I was so worked up and worried going for this appt. I was in and out and none the wiser after it and I just don't know how he could rule everything out without doing a test. Maybe I'm wrong and inflammatory bc or pagets don't have these symptoms but I am still so worried 

is it worth looking for a second opinion or am I just being silly and should take his word for it. I'm sorry if this is not the right place to post it
