Surgically remove 5 moles all at once- is it dangerous?

No: Removing 5 moles in one sitting is not a dangerous issue. Wish you good health! - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. Get HPV vaccine

Mole removal : Depends on size and location but since moles are small should not be dangerous but your surgeon can discuss risks more accurate

Most likely not: but that's a highly individual decision based upon your personal circumstances and clinical scenario. Your surgeon is best suited to tell you if removing all five at once is the best course of action or not. Hope this helps!
