As far as we know, fibroids are not hereditary. They do have a strange genetic pattern, however, in that many fibroids are monoclonal (derived from the same cell). In other words, if a woman has multiple fibroids, sometimes all of those fibroids come from a single cell as if that cell were cloned. This has led some people to postulate that a virus is involved in producing the fibroid cells that then grow and replicate like a cancer, but in a controlled, non-invasive fashion. If that is true, (we’re really guessing) then people in the same family could be susceptible; not because of genetics, but because of exposure to the same virus.
