Before we dive into these benign tumours that grow in your uterus. Not all women with fibroids have symptoms. Women who do have symptoms often find fibroids hard to live with. Understanding these uterine fibroids is the first step to figuring out.
What are fibroids?
Fibroids are muscular tumours that grow in the wall of the uterus. Fibroids are mostly benign and not cancerous at all. The medical term for fibroids is leiomyoma or just myoma. They can grow as a single tumour or can be many of them in the uterus. Their size can range from the size of apple seeds or as big as a grapefruit. In unusual cases, they can be very large.
Doctors believe that uterine fibroids develop from a stem cell in the smooth muscular tissue of the uterus (myometrium). A single cell divides repeatedly, eventually creating a firm, rubbery mass distinct from nearby tissue.
Most women do not have symptoms, it may be discovered fibroids incidentally during a pelvic exam or prenatal ultrasound. Some are so small that they would be invisible to the naked eye. Hence, understanding Fibroid and its treatment becomes more important. These days, Fibroid removal surgery is a common practice. There are various renowned hospitals which are known for Fibroid removal surgery.
A fibroid rarely causes acute pain. They are usually classified by their location; such as intramural fibroids grow within the muscular uterine wall, submucosal fibroids bulge into the uterine cavity, subserosal fibroids project to the outside of the uterus.
When do they occur?
Fibroids usually appear in women of childbearing age, between 30 and 40 years old and can also show up at any age. They can affect around 30 percent of all women by the age of 35 years and 20 to 80 percent by the age of 50 years. They usually develop during the years when oestrogen levels are higher. Fibroid removal Treatment is required in Critical conditions.
Why do they occur?
The cause of uterine fibroids remains unknown, but experience and research point out to some factors such as:
- Genetic changes: Some fibroids contain changes in genes that differ from normal uterine muscle cells.
- Hormones: oestrogen and progesterone that stimulate the uterine lining during each menstrual cycle appear to promote the growth of fibroids. Fibroids contain more oestrogen and progesterone receptors than normal uterine muscles.
- Extracellular matrix (ECM) is a material that makes cells stick together. Increased ECM is seen in fibroids which makes them fibrous.
- Other factors such as substances that help the body maintain tissues, may affect fibroid growth.
How do you know if you have fibroids?
The symptoms of uterine fibroids can vary based on their severity and is different from women. These can be influenced by the location, size, and the number of fibroids.
Some common signs and symptoms include:
- Heavy menstrual bleeding
- Menstrual periods lasting more than a week
- Pelvic pressure or pain
- Frequent urination
- Difficulty emptying the bladder
- Backache or leg pains
These symptoms can subside without any treatment but you should always know when you should consult with a physician to get further treatment, for your diagnosis of fibroids. You should see your doctor if you have:
- Pelvic pain that doesn’t go away
- Overly heavy, prolonged or painful periods
- Spotting or bleeding between periods
- Difficulty emptying your bladder
- Unexplained low red blood cell count (anaemia)
Seek immediate medical care if you have severe vaginal bleeding or sharp pelvic pain that comes suddenly.
Fibroids and their growth
Fibroids and their growth differ from women to women. In a study, the fibroid volume was measured by the computerised analysis of up to four MRI scans for a period of 12 months.
The growth patterns of uterine fibroids vary, they may grow slowly or rapidly, or they may remain the same size. Some fibroids go through growth spurts, and some may shrink on their own. Many fibroids that have been present during pregnancy shrink or disappear after pregnancy, as the uterus goes back to normal size.
The growth rates are not influenced by tumour size, location, BMI. These fibroids have spontaneous regressions and grow at different rates and the size does not predict growth rate, ethnicity can also play a role in the growth of a tumour.
The growth factors are proteins secreted by different cell types that are capable of modulating cellular growth, proliferation, and cellular differentiation. The myometrial mass is ultimately modified during pregnancy as well as in tumour conditions such as leiomyoma. They are considered to be one of the most frequent causes of infertility in women.
Some of the key growth factors of Fibroids
- Fibroids within the same women often have different growth rates despite having a similar hormonal milieu.
- Spontaneous regression in a small percentage of fibroids, in mostly premenopausal women.
- Tumour shrinkage after menopause can be seen
- Molecular markers may differ between tumours of different ethnic groups
- Tumour characteristics such as size and location were surprising
- Rapidly growing tumours can attain a large size while remaining solitary.
