Get follow-up: At the beginning of pregnancy, you should have a breast exam. If any lumps/bumps are found they can be imaged and less commonly, biopsied if there is concern. If the one that was biopsied was normal, i would recommend repeat imaging (likely ultrasound) in a couple of months of that lump and the other. Do your own exams also and if it is growing, be seen sooner. Usually these growths are benign.

Yes: Both benign and malignant tumors of the breast can be estrogen-sensitive, and grow during pregnancy. Complicating matters, the breast changes so much during pregnancy making identification of these lumps more confusing. Any new lump should prompt a visit to your ob; if concerning, you may be referred to a breast surgeon for evaluation+/-ultrasound+/-biopsy. As dr. Finke noted, most are benign.
