A fibroid is a benign mass of cells that exist within the tissues of the uterus. These lumps are not cancerous, though they can cause significant symptoms such as heavy menstrual bleeding, chronic pain, and more. Fibroids are an extremely common female condition, and are said to affect up to 80% of all women by age 50, though not every individual will present symptoms of fibroids. Many women that do experience difficulties with fibroids will begin to notice symptoms as their benign tumors gradually grow larger over time. This growth is likely to continue, along with worsening symptoms, if the woman’s fibroids remain untreated.
