If the leucorrhoea is yellowish watery and there is no vulvar itching, this situation is clinically important, and it is unlikely to be cured by itself without medication intervention, so it is recommended to have a gynecological checkup and to have a laboratory examination of the leucorrhoeal secretion. In this case, we should exclude the possibility of cervical cancer, endometrial cancer and fallopian tube cancer, especially pay attention to fallopian tube cancer, because fallopian tube cancer will show a large amount of yellowish watery secretion without any odor, which is often accompanied by pain in the lower abdomen, and it is recommended to do ultrasonography, and also do cervical cancer screening to find out whether there is epithelial lesion in the local area of the cervix. For this case, do not take it lightly, thinking that it is a general inflammation, as long as the resistance increases will be cured by itself, must pay attention to it, it is recommended to go to the hospital for a detailed examination.
