Final answer:
Combined hormonal contraceptives are a treatment option for a patient with mild endometriosis not trying to conceive.
Step-by-step explanation:
The treatment of a patient with mild endometriosis who is not currently trying to conceive can involve different options. One of the options is the use of combined hormonal contraceptives, which contain estrogen and progestin. These contraceptives work by suppressing the production of gonadotropin-releasing hormone (GnRH), which in turn inhibits the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), preventing ovulation and reducing the growth and activity of endometrial tissue.
