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. ...Read more

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

When biopsied mole comes back atypical does this mean that the mole would have for sure turned into melanoma? Have had 2 "slightly atypical" - scared!

When biopsied mole comes back atypical does this mean that the mole would have for sure turned into melanoma? Have had 2 "slightly atypical" - scared!

Watch carefully: Atypical means the cells are not completely normal. Depending on degree, can be pre-cancerous. See a dermatologist. Ask to have the pathology specimen re-read by a dermatopathologist. Just to be safe. If still atypical, follow the area closely with a dermatologist. ...Read more

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?

probably fine: Most likely part of the mole was above the surface of your skin and the rest was below. If the mole was just shaped of the underneath portion of the mole was not removed andthat is why you can still see the mole. If you are very concerned you can return to the doctor and review the original biopsy with him or her. ...Read more

Shave biopsy on mole. Derm used dermatoscope & said it was scratched. Biopsy not atypical w/ inflammation. Doc wanted 3 more slides to 2x check. Why?

Shave biopsy on mole. Derm used dermatoscope & said it was scratched. Biopsy not atypical w/ inflammation. Doc wanted 3 more slides to 2x check. Why?

Not sure: When you say "doc wanted 3 more slides to 2x check" I am not sure what you mean. Did you mean the doctor wanted to do another procedure on you to "confirm" the diagnosis? Or did he want the pathologist to take more sections from the same specimen? Sometimes "inflamed" moles can look pretty worrisome and the pathologist will take more samples from the whole specimen. ...Read more

What do abnormal cells in mole biopsy indicate?

How abnormal?: There is a range of abnormalities. The abnormality may be due to physical irritation, inflammation; dysplasia is also abnormal but removal of the lesion should take care of that. At the extreme, the abnormality may be due to cancerous cells. Please discuss the matter with your doctor. ...Read more

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. ...Read more

Is it typical for a dermatologist to send a mole biopsy out for a second opinion?

Mole biopsies: The art of identifying moles as premalignant, is very subtle and difficult. Consultation on a biopsy is a very, very frequent occurrence in dermatology. This does not mean that you have more to worry about. Just need you have to wait on the second consultation so that everyone is on the same page and realizes that a mole is premalignant, malignant, or completely benign. ...Read more

How long does it take for a lab to do a biopsy on a mole and for you to get results?

1 to 2 days: A biopsy is usually processed and reported in 24 to 48 hours. The things that could delay that is if the biopsy goes to a lab in another state for processing. At worst, this should only add another 24 hours to the entire process. ...Read more

No: The biopsy or re-excision can be done any time. You do not need to wait for the area to heal. You should go see a dermatologist or a primary care doctor who can check you and excise this area if there is any suspicion of melanoma in your case. ...Read more

Mole came back as compound nevus with congenital features. It was a scallop biopsy and the mole regrew in places within 2 months. Dr wasn't concerned and said it's normal to see this. Should I worry?

Mole came back as compound nevus with congenital features. It was a scallop biopsy and the mole regrew in places within 2 months. Dr wasn't concerned and said it's normal to see this. Should I worry?

Compuond nevus,: You have a recurrent nevus. If the diagnosis was compound nevus with congenital features you should not worry. As long as there was not any dysplasia. However pathologic interpretation of a reexcised recurrent nevus can be problematic so if you were to get the regrowth excised be certain the pathologist knows that this is a recurrent lesion after a shave biopsy. ...Read more

Previously begnign shave biopsied mole has darkened during pregnancy? Same size & shape just darker and slight color change. Concern?

Have your doc check: Melanocyte stimulating hormone is released in pregnancy, which can make moles or any pigmented area darker and change. This can be benign, but melanoma is also more aggressive in pregnancy for this reason. You need it checked out again by your doctor. ...Read more

Will it hurt to get a biopsy for a mole near mons pubis? Will the anesthesia hurt? I'm scared.

Will it hurt to get a biopsy for a mole near mons pubis? Will the anesthesia hurt? I'm scared.

Biopsy: Topical anesthesia applied prior to injecting the local anesthetic will minimize the discomfort of the "needle stick". If topical anesthesia is not available, the local injection and infiltration of anesthetic causes some initial mild burning/stinging which lasts a few seconds and then the skin becomes numb where anesthetic was injected. No need to be scared at all, it is a fairly simple& painless ...Read more
