If you ask how long it takes for melanoma to progress from an early stage to a late stage, it is generally impossible to give an accurate answer because each person's condition is different, patients' physical constitutions vary, and the growth rate of cancer cells also differs. Therefore, there is no precise answer to how long it takes for melanoma to progress from an early stage to a late stage.

If a patient contracts this disease, it is essential to seek medical attention promptly to prevent the tumor from spreading and metastasizing, leading to further deterioration of the condition. Patients must take it seriously and cooperate with the doctor's treatment, change some of their own bad habits, and earnestly cooperate with the doctor's treatment to control the growth of cancer cells and strive to extend their survival.
