Positive lung immunohistochemistry results for CK7 expression means that you may have lung cancer.
CK7 refers to cytokeratin 7, which is a specific indicator in immunohistochemistry tests and is a common marker for tumors originating from epithelial cells. Therefore, a positive lung immunohistochemistry result for CK7 means that the patient may have lung cancer. In this case, a combination of chest X-ray, chest CT, bronchoscopy, and other laboratory findings are needed to confirm the diagnosis.
The disease is mainly associated with smoking, ionizing radiation, heredity, air pollution and previous lung diseases such as tuberculosis and bronchiectasis. Typical symptoms include cough, blood in sputum, dyspnea, and fever. In addition, immunohistochemistry CK7 positivity may also be caused by lung metastasis of malignant tumors such as breast cancer and ovarian cancer.
All in all, patients need to go to the hospital in time, cooperate with the doctor to carry out a series of related treatments, control the development of the disease and regular follow-up.
