Are fibroids cancerous?

Fibroids are growths of the muscle that lines the womb, but they are not cancerous nor do they ever turn into cancer. In fact, around two in three women who have fibroids never even know that they have them.

Often, fibroids and miscarriages aren’t connected. Occasionally, however, fibroids may reduce the amount of blood supply to an embryo or make it difficult for that embryo to implant and grow, which can lead to a miscarriage.

Fibroids are really common. Around one in four women get them at some stage and in the vast majority of cases, they don’t cause fertility problems. Sometimes, though, fibroids can stop sperm from being able to get into the womb effectively.

Sometimes they can block the entrance to the fallopian tubes which is where the fertilised egg comes down in order to get into the womb. And in some cases, especially if you have lot of fibroids, it can make it difficult for that fertilised egg to find anywhere to implant in your womb and start to grow.

Fibroids are benign and non-cancerous growth of the womb. You can have either one or you can have many. However, there is no real definition of how many is too many, because one women might have one large fibroid which cause severe problems - while other women may have dozens of tiny fibroids which don’t cause any symptoms.

Fibroids are non-cancerous growths of the womb, specifically, the muscle that lines the womb. You can have dozens of them and they very much depend in terms of how many problems they cause, on their size.

Many women will have dozens of tiny almost pea sized growths and they won’t cause any symptoms at all, where some women will have one very large fibroid that can distort the cavity of the womb or grow outside the womb which can cause heavy bleeding, pain and sometimes other problems.

There are several treatments for fibroids which include medical treatments, tablets, hormones and surgical treatments. Some treatments don’t remove the fibroids, but shrink them instead. One of these is called uterine artery embolisation where the blood supply to the fibroids is cut off, so that it withers and fades away.

Another is called MRI focus ultrasound where high powered beams of ultrasound are directed at the fibroids using MRI control. Alternatively, key hole surgery or in the case of bigger fibroids, open surgery where the wall of the stomach is cut open, can be used to remove the fibroids. This is called myomectomy. As a last resort, and these days not very often done is hysterectomy, where the whole womb is removed.

There is a huge variation in the possible size of fibroids. Some women have lots of very small fibroids even as small as a pea. In some women however one single fibroid can grow very large . Very large fibroids can lead to symptoms including bloating, pressure on the bladder or bowel - and it can affect your fertility and lead to heavy or painful periods.

Fibroids largely depend on the hormone oestrogen in order to grow. Therefore, they tend to be most problematic for women in their early 20s until the menopause. After the menopause, these fibroids will almost always shrink. They may not disappear completely but they certainly shouldn’t cause problems in most people. But the only exception is if you take hormone treatment like HRT which contains oestrogen, so this can keep the fibroids going.

The most common symptom is heavy - and sometimes painful - periods. Usually fibroids do not cause bleeding between your periods. If you do get irregular bleeding between your periods or bleeding after the menopaus you should always get it checked out.
