Can a blood test detect teratoma?

Can a blood test detect a teratoma? The examination of teratoma mainly relies on B-ultrasound, CT, MRI and other imaging findings. Blood drawing is also necessary. For example, looking at the level of tumor markers can indirectly reflect the benign or malignant degree of the teratoma. In addition, blood drawing must be done before teratoma surgery to complete liver and kidney function, coagulation function, blood type and other tests. Blood drawing is required.

Rectal examination is very necessary for the examination of abdominal, pelvic and occult sacrococcygeal teratomas. X-ray films of the tumor site can reveal abnormal calcifications of bones and teeth in the tumor to confirm the teratoma, which is mostly mature teratoma. Gastrointestinal barium meal, barium enema and intravenous pyelography can understand the compression and displacement of the gastrointestinal tract or organs such as kidneys, ureters and bladder in the corresponding parts. CT and MRI examinations should be performed for teratomas that grow rapidly and have a wide range of infiltration to clarify the range of tumor infiltration and its adjacent relationship with important blood vessels and spinal nerves.

If a malignant teratoma is considered, the serum alpha-fetoprotein (AFP) and human chorionic gonadotropin (HCG) levels should be tested for diagnosis and prognosis. Ninety percent of malignant teratomas have elevated alpha-fetoprotein, while four percent of benign teratomas have abnormal AFP. It is also found that patients with elevated AFP in benign teratomas have a significantly increased recurrence rate after surgery.

Spine X-rays show a large or obvious widening of the intervertebral cavity, narrow pedicles at the site of the lesion, widened interpedicular distance, concavity of the posterior edge of the vertebral body, and in some cases, manifestations of spina bifida.

CT and MRI have obvious advantages in diagnosing teratomas, and both can better show the heterogeneity of tumors. On MRI images, teratomas appear as mixed signals, often with intact cyst walls, rich in fat signals, with or without intratumoral enhancement nodules, and usually, in addition to the tumor, are often accompanied by spina bifida or vertebral dysplasia.

After the above introduction, do you know what ovarian teratoma is? Female friends may wish to learn more about this in their spare time, which will help prevent and treat gynecological diseases such as ovarian teratoma as early as possible. Gynecological diseases can be serious or minor, and if they are not taken seriously for a long time, they will affect their health.
