I have found that i have a lump that is in my uterus. should i worry?

Lump?: Your term is confusing. The uterus is a muscular organ that is known to have fibroids, or what you could call lumps of muscular tissue within the walls. It can also have developed in an irregular shape. Why you would call it a lump & where it is located are two factors that make it difficult to answer. You should discuss any irregularity found with the doc who said it was there.
