2ww (2 week wait) for armpit lump - anyone had similar?

Hi everyone. I found a lump in my armpit and I've finished my antibiotics and it's still there. I went to see the gp again today and she's referred me to the breast clinic 2ww. These are her notes:

• Note - History: F2F ; seen with partner ; ; seen last week re lump in R axilla - noticed around 8 days ; not painful ; had some fluclox - no improvement ; no periods for while, no hormonal contraception ; no breast lumps ; aunt had breast cancer late 40s ; ; chaperone declined ; pea sized lump palpabl in axilla - deep, no overlying skin change ; no other breast lumps, axillary lumps palpable ; ; P/ 2ww breast
• Letter - A 2ww Referral Letter to Unknown

Anyone else had similar please??

Thanks for reading
