Does a biopsied mole grow back?

Does a biopsied mole grow back?

Mole biopsy: It depends on the type of mole biopsied. If your mole is raised and a shave biopsy was done the mole could grow back. Intradermal and compound nevi have a deep component so if the biopsy is a shave, the deeper component may grow back but this may take a long time.

Biopsy (Definition)

Biopsy is tissue removed by needle or cutting to remove part of a body part. It is usually a small amount of material that is processed by a pathologist. Most of the time it is stained and looked at through a microscope to arrive at a diagnosis. Special processes are done for some tissues or problems. The purpose is to tell what the problem is (diagnosis). ...Read more

I had a mole on back biopsied. Dr said it was very very slightly atypical, so she wants to recheck in 6 mos. If it grows back, is this a bad sign?

I had a mole on back biopsied. Dr said it was very very slightly atypical, so she wants to recheck in 6 mos. If it grows back, is this a bad sign?

Not necessarily.: Did she take out the whole mole or just biopsy part of it? Knowing that would help us answer the question properly. Get your follow-up as scheduled. But if it changes rapidly, call and see if you should go back sooner.

Does bad news come back faster for mole biopsies?

Does bad news come back faster for mole biopsies?

Not necessarily: The pathologist reads all slides from a certain date of service in the order that they are processed. However, there are times that the pathologist will call the dermatologist before the report is rendered but conversely, there are times that more serious diagnoses require consultation or further studies that can hold up the diagnostic process.

Mole biopsied 3 months ago came back as a benign congenital mole. It is now starting to growing back in areas. Is this a concern?

Probably not: This is likely is due to what we call 'recurrent nevus'. In other words, the biopsy showed a benign mole but did not completely remove it. It is now growing back. If you are worried, I would see a dermatologist to have it completely removed.

If a mole is removed by shave biopsy & comes back years later and is re-biopsied, is it normal the original biopsy shows normal but the 2nd displastic?

If a mole is removed by shave biopsy & comes back years later and is re-biopsied, is it normal the original biopsy shows normal but the 2nd displastic?

Yes: It is common for a mole to change Sometimes just the irritation from the shave can make it come back dysplastic but there are many environment factors like sun exposure which can change it.

Mole removed (w/out biopsy) & w/in 2 weeks it grew back. Not perfect circle & dark center & gets lighter until blends w/ skin around. Should I b concerned?

Mole removed (w/out biopsy) & w/in 2 weeks it grew back. Not perfect circle & dark center & gets lighter until blends w/ skin around. Should I b concerned?

Mole removal: First of all, moles should always be biopsied when removed. Often moles will regrow if the original mole was deeper below the skin and a shave removal was done. I would have original dermatologist look at the area who removed it to make sure it is just pigment regrowth from an incompletely removed mole.

I recently had a mole removed and it healed up perfect. The biopsy came back pos. For basil cell. What should I do now?

I recently had a mole removed and it healed up perfect. The biopsy came back pos. For basil cell. What should I do now?

Depends: Most of the time additional treatment is required. These tumors often have "roots" so to speak, and despite healing up, there is often residual skin cancer that will come back in a few months to years. Treatment at that time may not be as simple.

Hello. Biopsy and removal of mole on back this morning. I was fine but now bandaid is bloody. Is it normal to bleed so randomly and late afterwards?

Hello. Biopsy and removal of mole on back this morning. I was fine but now bandaid is bloody. Is it normal to bleed so randomly and late afterwards?

See below: It has been 16 hours since you wrote and bleeding should have stopped by now. It not you need to go the nearest emergency room. In general compression of the bleeding site is a good first measure to control bleeding. Bleeding can sometimes occur a few hours after a procedure.

Had deep shave biopsy done on mole that came back benign. After scan fell off, area has been red for two months. Looks like red circle. Will it go away?

Scarring: After about a year the new blood vessel ingrowth will lighten in color a bit. Most likely this will return to regular shin tone. If not, there may be some permanent skin pigment changes.

Mole removed. Over time it slowly grew back. Removed again and now shows dysplastic? Can original removal cause a false positive an subsequent biopsy?

False positive: Although previous surgery and/or trauma to an area can create difficult-to-interpret pathologic changes, that does not mean that dysplasia is not present. If a mole is dysplastic on pathology, then additional excision is required (assuming the biopsy had a close margin). Return to your dermatologist for a full discussion about this.

Scar tissue: Over a joint or area of thich skin, you can develop thickened itchy s ar tissue. Bio oil or Mederma may decrease the thickness and relieve the itching. If not see doctor for dilute kenalog (triamcinolone). Injection to soften scar.

Shave biopsy on mole done a month ago. Came back benign but it has repigmented. Is this concerning considering short time frame. Should I biopsy again?

Mole Biopsy: The mole that was biopsied has a deeper component that was not removed by the biopsy. There is nothing to worry about since the biopsy showed the mole to be benign.

My doctor biopsied a mole on my back and said it was attached to something internal. Meaning?

Depends: I think you need to discuss this with your doctor. Did it have a positive deep margin or are you dealing with something completely different?

Shave biopsy for mole done, came back totally benign. Still have reddish pink circle after scab fell off. When will this fade?

Shave biopsy for mole done, came back totally benign. Still have reddish pink circle after scab fell off. When will this fade?

Few months - normal: Normal for recent surgical site/scar to look pinkish red. The normal healing process takes a few months. You can help the healing by protecting the fresh scar from sun exposure. Some scar care creams also help.
