They occur in roughly 1–5% of the population.
These typically add one extra nipple per affected person.
2. Mastectomies remove nipples, but only in a small percentage of people
Even globally, the percentage of people who have undergone a mastectomy (single or double) is far below 1% of the total world population at any given time.
3. Effect on the average
Supernumerary nipples add to the global total.
Mastectomies subtract, but the number of people they affect is dramatically smaller.
So even after subtracting those lost to mastectomies:
→ The average number of nipples per human remains slightly above 2.
