Just diagnosed

Just got back from the surgon.  Had a lumpectomy on the 18th of july and they results of the biopsy follow.  I don't know what all this means and the surgeon has suggested mastectomy.  Can someone decifer the biopsy.
Biopsy, mass left brease, excision
Infiltrating lobular carcinoma Grade II-II (Tubules2, nuclei2 ,itosis1).
Perineural invasion and extension to adipose tissue.  Tumoral tissue involves inked margins.  
Note:  The main lesional tissue is app. 30x20 mm in maximum dimension; however, surrounding this main tumor mass are multiple other separate microscopic neoplastic nodules, sone of which are up to 1-2 mm in diameter.  The lesionaltissue extends to inked margins.
Gross Description:
Specimen is labled "left breast mass" and consists of a 53.7 gm mass of yellow, lobulated fibrofaty breast parenchymal tissue measusing 7.2X6.2X4 cm inked and cross sectioned.  Sross sectioningshows yellow lobulated adipose tissue surrounding a firm, il- defined mass of white tissue.  This area measures 2.3X1.9X1.9 cm and grossly extends to within 0.1cm of the inked resection margin, REP/7.AW/prc

Dear go go, Basically what is meant is that with the excision of the left breast mass - cancer was present.  There is evidence that not all of the cancerous tissue was removed with this biopsy (tumoral tissue involves inked margins).  Also although the main tumor mass was removed evidence of other separate microscopic cancerous nodules are seen in the specimen.  All of this would indicate that further surgery would be recommended in order to remove the entire cancerous area.  

The gross description only describes what the specimen looks like before being closely examined under the microscope.  Other information that is still pending ER/PR and HER 2 status which will be helpful information in terms of further treatment planning.
