I have a mole on my ass.

Pigmented nevus is a common benign skin tumor in our body, which is formed by accumulation of melanocytes. Just because there's a mole on your ass doesn't mean there's anything special. From the perspective of Feng Shui, you should ask Mr. Feng Shui, but from the perspective of our clinicians, it has no special significance, just a pigmented nevus in different parts.

Our main consideration is this part, because frequent rubbing may stimulate local cell malignant transformation, so we should closely observe the pigmented nevus in this part to see its size, depth and color change. In addition, are there any new satellite foci around, and is there itching or local ulceration of pigmented nevus itself?

If you have these suspicious manifestations, you should go to the hospital in time to see a doctor for face-to-face consultation, and if necessary, you can completely cut it open for pathological examination to see what the result is. If there is a possibility of malignant tumor, further treatment is needed.
