Not long ago, a patient with pulmonary nodules told me that a drop of blood can know the nature of the nodules, if you have heard of it, don't believe it, this is a rumor, if you have pulmonary nodules, or thyroid nodules, breast nodules, the following content will tell you the truth.
In fact, it is a tumor marker detection test, which uses some special substances produced by malignant tumors in the process of growth and reproduction, and tumor marker testing uses this to determine whether there is a tumor in the patient's body.
Speaking of which, do you want to ask, isn't it possible to find out? In addition to malignant tumors that can cause abnormal tumor markers, benign tumors, inflammation, or the use of drugs such as rabies vaccine may cause irritation and cause abnormalities in tumor markers, and even drinking, staying up late, pregnancy, etc., may also lead to abnormalities in tumor markers.
Therefore, in clinical practice, tumor markers are only used as one of the auxiliary examination methods to evaluate the nature of nodules, and no definite conclusions can be drawn from this, so don't be fooled.
If you have nodule problems, be sure to consult a medical professional. As long as you are my fan, you can join my fan group, tell me your questions, and I will answer them for you.
