Hi overeggedit. Waiting for results and then a treatment plan is the worst bit. I think the important things to know, and what will inform your treatment, is what grade the cells are (scale of 1-3, with 1 being most like normal cells and slower growing, 3 most abnormal and faster growing), whether it's hormone positive and whether it's HER2 positive.
I'm surprised the radiographer has been so certain that your lump is definitely cancer - they report on a BIRADs scale of 1 - 5, with 1 being almost definitely benign and 5 being almost definitely malignant. So even though the comments the radiographer made to you don't sound very positive, do remember that nothing is 100% until confirmed by biopsy.
There's lots of info on the Breast Cancer Care website about the different types of cancer (it can be any combination of HER2 positive or negative, oestrogen positive or negative, progesterone positive or negative). The golden rule of this thread is DON'T GOOGLE!!
You can ask for your pathology report if you want.
If you do have a positive result and it's a tumour that hasn't spread and isn't high risk, I'm sure you'll have plenty of time to take your holiday. Even though mine was high risk (HER2+, multifocal and spread to lymph nodes), it was still over 2 months until I had any treatment. If I'd opted for a simple mastectomy and no reconstruction, that would have happened sooner, and if I'd agreed to chemo before surgery, again that would have started sooner. It was also Christmas hols right in the middle of all of this, so that added another couple of weeks on. My surgeon was very certain that the delay wasn't making a difference, looking back I'm not entirely convinced, but I'll never know!
Is someone going with you when you get the results? I went with a friend, so glad I did, as I wasn't really taking anything in apart from 'it's cancer' when I got my results.
Wishing you all the best.
Wave to everyone else.
