One week after diagnostic scraping, there is still blood in the vagina, which is related to various factors such as endometrial cancer, infection, incomplete endometrial scraping and so on. 1. Endometrial cancer, although some patients have undergone diagnostic scraping after endometrial cancer, the endometrial lining has already undergone lesions, and irregular bleeding from the pubic area may occur, so there may be blood one week after diagnostic scraping. 2. Infection, if bacteria or other pathogens invade after diagnostic scraping and cause infection, the infection may also lead to bleeding. 3. Incomplete removal of endometrium, if the endometrium is not completely removed by scraping, part of the endometrium will continue to be stripped and bleed. After the scraping, you need to observe the bleeding situation, if the bleeding increases or the bleeding is intermittent and not clean, you need to consult a doctor in time.
