Fibroids are one of the most common benign tumors of the female genitalia, mostly due to the influence of certain factors that can cause lumps to grow on the uterine wall. About 20% of women over the age of 30 suffer from uterine fibroids, and there are five groups of people who are most prone to it and need special attention. 1, people affected by genetic factors: manifested in racial differences and family aggregation. For example, the incidence rate of blacks is 2 to 3 times higher than that of whites or Asians, and people whose immediate family members or sisters have had fibroids are 4.2 times more likely to have the disease than those without a family history of the disease. 2. People with factors that cause ovarian hyperfunction: for example, polycystic ovary syndrome. There are also diseases with ovarian endocrine function, such as granulosa cell tumor and ovarian granulosa cell tumor, which can lead to the occurrence of uterine fibroids. 3, related to the number of births: the incidence of uterine fibroids is inversely proportional to the number of births. Nowadays, elderly people in their 70s have had at least four children in their time, which explains why women rarely suffered from this disease in the past. This is because the ovaries do not ovulate and hormone secretion is at a low level during this period of time, thus protecting the health of the uterus. 4, affected by the body: why eat the same food, or sisters suffer from the disease but not themselves, this is related to the individual’s physique. Because the hormone action needs receptors, some people have more sensitive receptors, easily affected by hormones, then relatively easy to suffer from uterine fibroids. 5, related to life: the first is the obesity factor, research shows that every 10 kg increase in weight, the risk of fibroids increased by 21%, because the obese physique is easier to synthesize estrogen.
