Fitting women with post mastectomy breast prosthesis, I have always
heard surgeons stating that women with multiple biopsies have more
malignancy.  This is what a search on the Internet turned up:

Each time a biopsy anywhere on the body is performed there is growth
factor secreted for healing the tissue.  Not necessarally all cancers
are life threatening.  All prostate cancers in men are not the causative
factor for death, as shown on autopsy.  Some breast cancers can be slow
growing and take years to kill a woman, especially after menopause when
she is older and cell division is slower and hormones are lower.  But
the biopsy itself (and repeated biopsies) will cause indiscriminate
cellular growth each time, even of latent cancers that would not have
progressed very fast otherwise.

Surgeons are less likely to have a "wait and see" attitude about breast
tumors than prostate cancers.
