The full name of human epididymis protein is human epididymis protein 4, abbreviated as HE4. human epididymis protein 4 is a sensitive marker for ovarian cancer. It has been found that the serum of ovarian cancer patients has high levels of human epididymis protein 4, which is not easy to be detected because of the lack of obvious symptoms in the early stage of ovarian cancer. However, human epitestosterone 4 will be obviously elevated in the early stage of ovarian cancer, and it is mostly used in the screening of early ovarian cancer patients. It can improve the early diagnosis of ovarian cancer, early detection and early treatment, and the cure rate of patients will be significantly improved. Before the examination, you need to pay attention to rest, ensure sufficient sleep, eat a light diet, do not drink alcohol and avoid spicy food. Overall, if you find that human epithelial protein 4 is significantly elevated you need to go to the hospital in time for examination and treatment under the guidance of a professional doctor.
