Worried - Told I haven't got breast cancer but need another one or two biopsies

Routine mammogram showed calcification (I'm 67).  I was given a stereotactic vacuum assisted breast biopsy.  The procedure itself was horrendous and extremely distressing, I felt massive stabbing pain twice and cried out in pain.  I was told I felt pain more than most.  I also had a bleed occur behind one eye, which I have been told is pure coincidence.  That is not my main worry, although still an ongoing problem.

I went back for my results and was told by the consultant that I haven't got cancer.  However, I need to have another biopsy to take more cells to test if any could turn cancerous in the future.  If there are I would need to go back for a third procedure to remove these rogue cells.  He wanted the second biopsy done in two weeks but after he did an ultra scan realised it would be a while before this could be carried out as I had two massive painful lumps, which he said were caused by trauma from the two needle insertions.

This is the letter he sent to my doctor

This patient attended for results of biopsies for area of screen detected calcifications as follows
 
Right breast VAB: Atypical ductal hyperplasia and columnar cell lesions, benign calcification. B3
 
Results explained. MDT recommendation is for Vacuum excision.
 
Patient found the procedure painful and traumatic.
 
On examination: there are two haematomas in the breast at the site of the biopsy:
 
Plan: Review in 4 weeks, re-examine plus post clip mammograms and arrange repeat assessment.
Question:  Does this seem right?  I am worried now that the radiographer did not do the first test properly and that there still could be cancer.  Why did they not do all these tests from the first biopsy?
