Are there correct/wrong behaviours that can prevent or favour the development of fibroids?

There are some risk factors that can be associated with uterine fibroids, such as oestrogens and progesterone (because fibroids have many receptors for these hormones), several growth hormones and genetic predisposition. Other factors that may favour the development of uterine fibroids include a lack of vitamin D and a stressful life. However, fibroids are probably caused by a number of different factors that may also interact. Usually, they develop in the period of fertility (roughly, between the age of 16 and 50), when the level of oestrogens is highest, and they tend to stop developing as oestrogen levels decrease, following menopause. It is a generally-held opinion that they develop more often in overweight or obese women, because excess weight makes oestrogen levels in the body soar. As for prevention, there are strategies that can prevent their growth.
