Unlikely.  It's more likely you are noticing swelling, scar tissue, or an adjacent lipoma.  

You should call the physician that performed the surgery and have them examine the surgical site.  

I'm sorry you're anxious about your recent procedure.  

Limited cautery has not been shown to cause any harm to unborn children.  


Lidocaine is safe during pregnancy; epinephrine is often added to the lidocaine.  Epinephrine is likely safe to use in the small quantities needed for a skin biopsy, but many physicians, myself included, generally use lidocaine without epinephrine working with women that are pregnant.  

I hope that I've answered your question and have made you feel more comfortable with the care you received.  

It is very difficult to tell you whether your moles are abnormal based on a photograph--there is no substitute for an in-person skin examination.  Your physician will have a much better view in person with better light.  They may also use other tools to examine your skin such as dermoscopy.  

If you have concerning moles, especially if you've never had your moles check before, you should make an appointment with a board-certified dermatologist.  

Lipomas can occasionally become tender.  In addition, angiolipomas are a variant of lipomas that are often tender.  

Lipomas are generally straightforward to remove if causing pain or discomfort.  Dermatologic surgeons remove these routinely in the outpatient setting with local anesthesia.      

Lipomas are tumors of fat cells that are generally above the muscular layer.  If your physician did an examination and determined it was a lipoma without any irregular features there is no need for imaging in the vast majority of cases.
