What tests are needed to diagnose melanoma

After suffering from melanoma, there are some tests that must be done, because through these melanoma tests, the patient's condition can be more clearly understood, which is very important for the treatment of melanoma. So, how is melanoma detected? The following will tell you about the examination methods for melanoma.

1. Pathological examination

It is a reliable means of examining melanoma and the main method of differential diagnosis. When conditions permit, suspicious lesions should be removed including the entire thickness of the tumor and the infiltrated tissues of all layers of the skin, and a biopsy should be performed to obtain a pathological diagnosis. Avoid needle aspiration, scraping, forceps extraction, incision or punching biopsy to prevent the spread of lesions.

2. Electron microscopy

Melanosomes in malignant melanoma at different stages of development can be observed, which are characteristic and can be identified with other tumor cells and melanophages. Observation of immunoenzyme label (S-100), monoclonal antibody HMB-45 and flow cytometric DNA analysis are of diagnostic value for confirming malignant melanoma.

3. X-ray examination

Chest X-ray should be performed for possible, asymptomatic lung metastases. If metastases are suggested, lung tomography or CT scan should be performed to confirm melanoma.

The above is how to detect melanoma. I hope it will be helpful to everyone. If you have melanoma, you must go to the hospital in time for active treatment to prevent the disease from getting worse and causing more serious harm.
