How do women check for ovarian tumors

Ovarian tumors are divided into epithelial tumors, sex cord-stromal tumors, germ cell tumors, mixed component tumors and tumors of uncertain tissue origin based on their histopathology, and are further divided into benign, borderline and malignant based on the degree of cell differentiation.

Imaging examination methods: Currently commonly used methods include traditional X-ray examination (gastrointestinal radiography, barium enema), ultrasound, CT, MRI, etc.

1. Traditional X-ray examination: (1) Abdominal plain film: can show calcification in huge tumors, such as bones, teeth, and large calcifications in teratomas (2) Digestive tract barium contrast: Ovarian malignant tumors are often large, with pelvic implantation and metastasis, compressing or eroding the intestines. Barium enema helps to observe whether the intestines in the pelvis are invaded. Yulin Yinfeng International Chinese Medicine Port Whole digestive tract contrast helps to observe whether the stomach and small intestine are invaded. In addition, the primary tumor of ovarian metastasis often originates from the digestive tract. Therefore, for young women and when the ovarian tumor has more solid components, digestive tract contrast should be performed to exclude tumors originating from the gastrointestinal tract.

2. Ultrasound: Transabdominal B-ultrasound is the preferred method, which is simple, easy and inexpensive. It can make a diagnosis based on the shape of the tumor, and its role in distinguishing cystic, solid, benign and malignant tumors has been recognized. It also plays an important role in the diagnosis and staging of advanced tumors. Color Doppler can detect blood flow inside and outside the tumor, and it is also of great value in assisting in distinguishing benign and malignant tumors. Benign tumors often have no blood flow signals or regular small blood vessels. Due to high metabolism and rapid growth, malignant tumors have new blood vessels or arteriovenous fistulas, which form a large pressure difference, manifested as high blood flow velocity and low resistance.

3. CT scan: CT scan is the most important and most commonly used method for the examination of female pelvic tumors. Ovarian tumor cells are prone to fall off and implant in the abdominal cavity, resulting in extensive abdominal metastasis, so it is considered a pan-abdominal lesion. CT has a wide scanning range and is more sensitive than other methods in showing small lesions and detecting small amounts of fat and calcification, so it is the most commonly used. The purpose of CT examination is to diagnose, identify and determine the scope of pelvic tumors, especially to provide tumor staging information for tumor patients so that a reasonable treatment plan can be formulated before clinical surgery.

4. MRI scan: It has the characteristics of being able to directly provide multi-axial images, high soft tissue resolution and multi-sequence scanning procedures. The advantages are that it can clearly display the tumor structure, provide certain tumor-specific signs, and provide a clear relationship between the tumor and the surrounding normal tissues and organs to more accurately determine the tumor location, nature and invasion range.
