There is no known cause that makes fibroids grow but what is known is that fibroids grow rapidly with high levels of female reproductive hormones. In preparation for pregnancy, oestrogen and progesterone stimulate the development of the uterine lining during every menstrual cycle and so do the hormones that appear to promote the growth of fibroids as well. This is understood by the fact that fibroids contain more oestrogen and progesterone receptors than are present in normal uterine muscle cells. During pregnancy, when hormone levels are high, fibroids grow faster making it evident that fibroids are under hormonal control. This is how anti-hormone medication as advised by the best gynecologist in Chennai helps in the treatment to shrink uterine fibroids.
Though it is not clear as to what causes fibroids, few factors that are found to increase the risk of developing fibroid growth may include:
A woman’s uterus is shaped like a pear and on average it is approximately 3 inches long. Fibroids can grow in several places both inside and outside of the uterus. Fibroids are classified and given different names according to the places fibroids are located in/on the uterus and also how they are attached. Specific locations where uterine fibroids can grow include:
Pedunculated fibroids are also located on the outside of the uterus but are connected to the uterus with a thin stem.
The location and size of the fibroids is important in the diagnosis and treatment. The best gynaecologist in Chennai will suggest treatment method that will work best for the size and number of fibroids in that place.
Growth of uterine fibroids can be very slow or they may enlarge rapidly. Fibroids can also remain the same size for years or even shrink on their own. Fibroids that are found to be present during pregnancy often disappear after delivery. However, with menopause, the risk of developing new fibroids is minimal and fibroids that are present are likely to shrink.
Fibroids grow in the form of clusters or as single nodules ranging from 1mm to 20cm in diameter. Many small fibroids can develop in to a cluster of fibroids or grow as one large, dominant fibroid. According to a research study, the average rate of fibroid growth is 89% per 18 months. With this as a point of reference, a two centimetre fibroid is expected to take four to five years to grow up to be double that diameter. Also, it is revealed that very small fibroids have the tendency to grow more quickly than the larger ones.
Following is a guide that uses a reference point to generalize the size of fibroids as follows: small,
Large (10cm+) varies from the size of a mango to a watermelon.
Specific measurements of fibroid size and estimation of growth using ultrasound has become more and more important. The size, shape and position of any fibroids can be determined by evaluating the uterine cavity. If an asymptomatic fibroid is detected and measures less than 5 cm in diameter, it may just need watchful waiting whereas for a fibroid that measures 5 cm or more and continues to grow, the best gynaecologist in Chennai may suggest a suitable treatment.
Fibroids that remain small without noticeable symptoms often go undetected. A small fibroid that has a larger change in size concludes that it is growing. Small fibroids with an increase in diameter of >20% is likely to indicate “true growth.” The true growth of a fibroid is more clinically relevant as fibroid growth is linked to increased symptomatology. Fibroid growth and symptom progression are found to be the leading cause for hysterectomy. Larger fibroids can make the uterus distended and enlarged thus causing more obvious symptomatic changes in body.
Additionally, the usual course of treatment for fibroids that are causing no symptoms is watchful waiting. However, as fibroids increase in size, they may cause more significant impact on the body. They can occupy the space meant for other organs and can cause discomfort or pain. Some of the effects that can arise when fibroids grow beyond smaller sizes are:
Large fibroid can even lead to expansion of the uterus to the size equivalent to a pregnancy entering the 3rd trimester. Women with large fibroids will have to take imaging studies done to evaluate uterine fibroid size. Not evaluating the fibroid size often leads to significant symptoms, eventually requiring emergency removal. Hence, the size of a fibroid is the primary symptom to determine whether treatment is required and if the woman needs to undergo fibroid removal in Chennai.
