If a woman has a strong vulvar odor during menstruation, accompanied by persistent pain in the lower abdomen, it is important to consider that it may be caused by endometrial inflammation, accompanied by an increase in the amount of menstrual flow, prolonged menstrual period, as well as abdominal pain, and blood tests may be accompanied by an increase in leukocytes and neutrophils, which will require active anti-inflammatory and pain-relieving treatments. If a woman has a strong vulvar odor during the non-menstrual period, it is often considered to be caused by vaginitis or cervicitis, such as bacterial vaginosis, trichomoniasis, and so on. For elderly women with long-term vulvar odor and persistent ulcers, it is important to be alert to the possibility that vulvar cancer may be the cause of the phenomenon, and to go to the gynecology department of the hospital as soon as possible for examination and diagnosis. For persistent vaginal secretion of bloody discharge in large amount with foul-smelling leukorrhea, cervical cancer, endometrial cancer with infection, fallopian tube cancer and other malignant diseases cannot be ruled out, and further examination and diagnosis are needed.
