Can a negative ultrasound check for ovarian cancer?

Transvaginal ultrasonography is able to find out whether there is a lump in the ovary, but further pathological examination is necessary to determine whether it is ovarian cancer.
Ovarian cancer, also known as ovarian malignant tumor, is one of the common malignant tumors of female reproductive organs. The cause of occurrence is not clear, and it may be related to genetic factors and endocrine factors, etc.. Patients present with symptoms such as abdominal distension, abdominal pain, lower abdominal mass, irregular uterine bleeding, postmenopausal bleeding, and lethargy and fatigue.
Yin ultrasound is short for vaginal ultrasound, also known as intracavitary ultrasound, which is a method of ultrasound diagnosis by placing the ultrasound probe into the vagina. It is sensitive to uterine arteries and blood flow to the ovaries, and is especially suitable for the initial observation of ovarian and pelvic organ lesions.
After the ovarian mass is detected by vaginal ultrasound, the next step of examination should be done to confirm whether the ovarian mass is ovarian cancer, and the methods of confirming the diagnosis mainly include CT, molecular diagnosis of tumors, and histopathological examination.
In addition, when there is abnormal vaginal bleeding, vaginal ultrasound is generally not recommended, because vaginal ultrasound examination at this time will increase the chance of infection. Please follow your doctor’s instructions.
