If a woman has a bad smell in her private parts, it is advisable to check for any related gynecological diseases.1. Do a routine white belt examination to see if there is a mixture of trichomonas, mycobacteria, bacteria, and miscellaneous infections. Usually with vaginal inflammation, odor such as foul smell and fishy smell may appear. 2. Do internal gynecological examination to see if there is chronic cervicitis. Also check cervical TCT and HPV test, also known as cervical cancer screening. If the cervix has serious lesions, there will be a relatively large odor with foul smell. 3. Do gynecological ultrasound examination to see if there are gynecological tumors. For example, uterine fibroids and endometrial cancer will appear to have odor.
