Submucosal fibroids grow just under the uterine lining. They're the most likely to cause heavy bleeding and infertility. The uterine fibroid market research study shows that submucosal fibroids are the fastest‑growing type, driven by improved diagnosis (hysteroscopy, saline infusion sonography). Why the attention? Because they're often treatable with outpatient procedures.

What's the treatment? Hysteroscopic myomectomy — a scope is inserted through the cervix, and fibroids are shaved away. No incisions, no hospital stay. The uterine fibroid market trends highlight that the fastest‑growing diagnostic tool is MRI, which can distinguish submucosal from other types.

But submucosal fibroids can be tricky. If they're large or multiple, they may require multiple procedures. And they have a higher recurrence rate than other types.

The bottom line: if you have heavy bleeding, ask for a saline infusion sonogram or hysteroscopy. You may have a submucosal fibroid that's easily treatable.
