Are fibroids related to uterine cancer?
No. The Family Health Service is direct about it: the great majority of fibroids are benign, unrelated to uterine cancer, and do not increase the chance of cancer in future.
That sentence carries three separate assurances: the fibroid itself is benign, it is not the same thing as uterine cancer, and having one does not raise the chance of cancer later. The third is the most often confused — many people fear something benign will “turn” malignant, and the Department’s wording does not support that worry.
The naming itself causes confusion: 子宮肉瘤 is one of the alternative names for a fibroid, yet in other contexts 肉瘤 can denote a malignant tumour. Which is meant in a particular case is for a doctor to explain.
What are the symptoms of uterine fibroids?
Most often none. The Family Health Service states that most women with fibroids have no symptoms; where there are symptoms, periods are usually heavy, and a minority have period pain.
| Situation | How it shows | Why |
|---|---|---|
| Most cases | No symptoms at all | Often found incidentally during another examination |
| Where there are symptoms | Heavy periods; a minority have period pain | This is the commonest presentation |
| A larger fibroid | Abdominal pain or a swollen abdomen | A matter of size, not of whether it is benign |
| Pressing on the bladder | Needing to pass urine more often | Pressure from where the fibroid sits |
