Uterine fibroids: most need nothing, and the uterus is rarely the only option

What fibroids are, and what they are not

A fibroid is a benign growth of the muscle wall of the uterus. Benign means not cancer. They are extremely common, they often occur in more than one place, and their growth is driven by oestrogen, which is why they tend to grow during reproductive years and shrink after menopause.

The word that causes the most unnecessary distress is tumour. A fibroid is technically a tumour in the sense of a growth, and it is not a cancer. The malignant counterpart, leiomyosarcoma, is rare. It cannot be reliably distinguished on ultrasound alone, and that genuine uncertainty is sometimes used to create urgency where none exists. The findings that raise real concern are rapid growth, especially growth after menopause, new persistent pain, and specific features on MRI. If you are told there is a possibility of cancer, ask what specific finding prompted that concern. There should be a nameable one.

What position matters more than number. A fibroid inside the cavity, called submucosal, is the type most likely to cause heavy bleeding and to affect fertility, even when small. One in the wall, intramural, may cause bleeding and bulk symptoms. One on the outside, subserosal, usually causes pressure symptoms rather than bleeding and may cause nothing at all. Ask which type you have, because a 2cm submucosal fibroid can cause far more trouble than a 7cm subserosal one.

This is why size alone is a poor guide. A number in centimetres sounds objective and gets used as an argument. The real questions are: what symptoms do you have, how much are they affecting your life, how old are you, and do you want a pregnancy.

Doing nothing is a real treatment

If your fibroids were found incidentally on a scan done for something else and you have no symptoms, the appropriate management is expectant: leave them, review if symptoms develop, and no procedure. This is not a compromise; it is what the evidence supports.

Age changes the calculation substantially. Fibroids shrink after menopause. A woman of forty-eight with manageable heavy periods and a fibroid has a different decision to make than a woman of thirty-two with the same fibroid, because for the first, waiting a few years may make the problem disappear on its own. This argument is rarely put to women, and it should be.

Two cautions on the other side. First, watchful waiting requires that heavy bleeding is not quietly making you anaemic. Get your haemoglobin checked. Severe iron-deficiency anaemia from years of heavy periods causes exhaustion, breathlessness and heart strain, and women often normalise it because they have felt that way for years. Second, watchful waiting means review, not disappearance from care. Ask for a defined interval.

Also be clear about what watchful waiting is not. It is not an answer to bleeding after menopause, to bleeding between periods, or to rapid growth. Those need investigation, and the reason is that the important thing is not the fibroid, it is what else might be there.

The bleeding ladder, which is where most women are short-changed

If heavy bleeding is your main symptom, there is a sequence of treatments and hysterectomy sits at the end of it.

The hormonal intrauterine device that releases progestogen is first line for heavy menstrual bleeding in many guidelines. It is placed in an outpatient visit, without surgery or anaesthesia, and it thins the lining of the uterus so that bleeding often reduces dramatically. It is reversible. Irregular spotting for the first few months is common and is the main reason women give up on it early. It can be pushed out if the uterine cavity is significantly distorted by fibroids, so it suits some fibroid patterns better than others.

Tranexamic acid is a non-hormonal tablet taken only during the days of bleeding, which reduces blood loss. Non-steroidal anti-inflammatory drugs like mefenamic acid reduce both bleeding and pain. Combined hormonal contraceptives and progestogens are also used. None of these shrink the fibroid, and that is fine, because the fibroid is not the problem; the bleeding is.

Iron treatment deserves its own mention because it is the most neglected. If heavy periods have made you anaemic, correcting the anaemia with iron, oral or intravenous, may make you feel transformed even while the fibroid remains. Many women who believe they need surgery because they feel so unwell are describing iron deficiency, not fibroid bulk.

GnRH agonists temporarily switch off oestrogen, shrinking fibroids and stopping bleeding. Because they cause menopausal side effects and bone loss, they are used for a limited period, typically to shrink a fibroid before surgery or to bridge a woman to menopause, not as a long-term solution.

Endometrial ablation destroys the lining of the uterus to reduce bleeding. It is a day procedure that treats bleeding but not bulk, is not suitable if the cavity is distorted, and is not appropriate if you want a future pregnancy.

The reasonable test of whether you have been offered proper care is simple: has anyone offered you a hormonal IUD, tranexamic acid, or iron? If the answer is no and the recommendation is hysterectomy, ask why each of these is unsuitable for you specifically. There may be a good answer. You are entitled to hear it.

Procedures that keep the uterus

Myomectomy removes the fibroids and leaves the uterus. It can be done through a hysteroscope for submucosal fibroids inside the cavity, by keyhole surgery, or through an open incision depending on size, number and position. Reported reintervention risk at five years is around 12%, which means the large majority of women who keep their uterus do not need a further procedure. It is the standard choice for a woman who wants to preserve fertility, and a legitimate choice for a woman who simply wants to keep her uterus.

The honest trade-offs: myomectomy can involve more bleeding during surgery than hysterectomy, new fibroids can grow, and it leaves a scar in the uterine wall which may affect how a future delivery is planned. Ask what your surgeon's approach would be, and ask specifically whether the number and position of your fibroids make it technically reasonable.

Uterine artery embolisation blocks the blood supply to the fibroids through a fine catheter placed in an artery, usually via the groin or wrist, by a radiologist rather than a surgeon. There is no incision into the abdomen and recovery is generally faster than surgery. It works well for bleeding and bulk symptoms. Reported reintervention rates are higher than for myomectomy in some series, and there is a period of significant cramping pain afterwards. Its effect on future fertility is less well established, so it is generally not the first choice for a woman actively planning pregnancy.

Radiofrequency ablation of fibroids, done laparoscopically or transcervically, uses heat to destroy fibroid tissue while leaving the uterus. MRI-guided focused ultrasound uses focused sound waves through the skin. Both are uterus-sparing and both have narrower eligibility criteria and less long-term data than myomectomy or embolisation, and availability in India is limited. If one of these is proposed, ask what the reintervention rate is and how many the centre has done.

Hysteroscopic resection deserves separate emphasis because it is the answer people miss. If your problem is heavy bleeding and your fibroid is submucosal, sitting inside the cavity, it can often be shaved out through the cervix with no abdominal incision at all, as a day procedure. Women have had their uterus removed for a problem that a hysteroscopic resection would have solved. Ask whether any of your fibroids are submucosal.

When hysterectomy genuinely is the right answer

This page argues for the ladder, not against the top of it. Hysterectomy is definitive: fibroids cannot recur, and for some women it is unquestionably the right choice.

Situations where it is reasonable and often best: you have completed your family and want a permanent solution rather than a series of procedures; you have very large or very numerous fibroids where myomectomy would be technically difficult and likely to fail; you have tried the medical ladder and it has not worked; you have severe anaemia from bleeding that will not settle; or there is a suspicion of malignancy. A woman who has been bleeding heavily for years, is exhausted, has finished having children and wants it over with is making a rational choice, and it is her choice to make.

Two things should still be true even then. First, you should know what else is being removed. Removing the uterus does not require removing the ovaries, and removing healthy ovaries before natural menopause causes sudden surgical menopause with consequences for bone and cardiovascular health. Ask explicitly: are my ovaries being removed, and if so, why? Get the answer in writing on the consent form. Second, you should know the route: vaginal, laparoscopic or open, since recovery differs substantially.

And be aware of what hysterectomy does not fix. If your main problem is pelvic pain rather than bleeding, removing the uterus may not resolve it, because the pain may be coming from something else such as endometriosis, adenomyosis, bowel or bladder conditions, or musculoskeletal causes. Women who have a hysterectomy for pain of unclear origin are the most likely to be disappointed.

Fibroids, fertility and pregnancy

Most women with fibroids conceive without difficulty. The ones that matter for fertility are those distorting the cavity, particularly submucosal fibroids, which can interfere with implantation. Removing those can improve the chance of conception. Removing fibroids that sit on the outside of the uterus, in a woman with unexplained infertility, has much weaker justification.

So if you are being advised fibroid surgery for fertility, the question is which fibroids and where. Ask whether any are inside the cavity, whether a hysteroscopic assessment has been done, and how the surgery is expected to change your chances.

In pregnancy, fibroids are usually uneventful. They may grow, and a fibroid can undergo red degeneration, causing significant pain that is managed with rest and pain relief rather than surgery. Fibroid removal is generally avoided during pregnancy because of bleeding risk. A large fibroid low in the uterus can obstruct labour and may be a genuine reason for a planned caesarean, but the presence of any fibroid is not by itself a reason.

If you have had a myomectomy, tell whoever manages your pregnancy. The scar in the uterine wall affects delivery planning, and this is one of the trade-offs to weigh when choosing between myomectomy and other options.
