When a woman suffers from endometrial cancer, the primary treatment method is surgery, but there are some special circumstances. For example, if the lesion in the woman is relatively minor, it is atypical hyperplasia, which is a precancerous condition, or it is in the late stage of the disease, or in cases of recurrent endometrial cancer. At this time, treatment can be administered using progestogen drugs, applying high-dose long-term oral intake of effective progestogens, which can suppress the cancerous transformation of the endometrial lining and inhibit the further proliferation of cancer cells. Generally, it involves continuous oral administration for 12 weeks, which is three months, followed by a diagnostic curettage to evaluate the therapeutic effects of the drug. In addition, radiation therapy can also be considered.
