Told i have the start of adenomyosis from ultrasound. how can they tell and how long until it starts and how fast does it spread?

Not Cancer: Adenomyosis is defined by the presence of endometrial tissue within the muscular wall of the uterus (myometrium). It is frequently associated with heavy and painful periods. 20% of patients have associated endometriosis. The findings on ultrasound are nonspecific and the sono can be relatively insensitive to the condition. The condition should regress with menopause. Not a malignant condition.

Thickened tissue: Adenomyosis is thickening of the tissue between the endometrium (inner lining of the uterus) and the rest of the uterine tissue (myometrium). It is common and may be associated with pain, cramps, heavy bleeding, and bloating around/during your period. You may also have no symptoms. It is benign and not cancer so it doesn't spread. If you are having symptoms, follow up with your gynecologist.
