I have a lump in my left breast , started out a three years ago the size of peanut , had altrasound done and it measures 3.6 x 2.1x 3.3 cm, I am very nervous , as I usually do alternative when ever I can , I am 54 and just starting menopause , I have read where these can appear and then reach a certain size and never get any bigger is this true???? it is stated on the ultrasound report as""" a large lobulated hypoechoic mass at 12 oclock Some microlobulation and spiculation not excluded non dependently although area of marcrolobulation and increased through transmission are also noted """ then it also says!!! no other abnormalities !!! and under inpression it says finding suspicious for left breast malignancy , ultrasound guided core biopsy is recommended .... I am confussed and worried , if I go with the core biopsy will any of these cell if cancer spread through blood and and cells by opening into the breast .need some input thanks sharon
