Moles are caused by a high density of pigment cells in the skin. Some moles are present at birth, while others develop during adulthood, according to the US health website Healthline .
If the mole grows back after removal, it is necessary to monitor and see a dermatologist for examination.
However, there are moles that are cancerous or can become cancerous. Cancerous moles will have irregular borders, unusual colors, or grow abnormally large. If you suspect a mole is skin cancer, you should see a doctor as soon as possible for timely diagnosis and treatment.
One of the most common reasons people want to remove moles is for cosmetic reasons. Mole removal surgery is a common medical procedure that can be easily performed by a dermatologist.
Common methods used to treat moles include excision, shaving, or laser therapy. Before performing the procedure, the doctor will use a numbing medicine around the mole. This will help reduce pain and discomfort for the patient, according to the non-profit medical center Cleveland Clinic (USA).
Some moles that are removed may grow back. In that case, the mole needs to be monitored regularly and checked by a doctor regularly. This is especially important if the mole changes in shape, size, or color. A mole that grows back may be skin cancer, but it may not be.
If you suspect a mole is skin cancer, you should see a doctor as soon as possible for timely diagnosis and treatment.
There are many reasons why a mole can grow back after it is removed. The first reason is that some of the mole tissue was not completely removed and treated. The remaining tissue has the ability to regenerate and grow back into a new mole.
The likelihood of a mole reoccurring also depends on the treatment method and the characteristics of the mole. For example, surgical excision will completely remove both the surface and the underlying layer of cells of the mole. Therefore, the likelihood of a mole reoccurring is relatively low.
Meanwhile, the method of removing moles by using a medical knife to scrape the surface layer of the mole will increase the risk of the mole growing back. The reason is that the cells in the deeper layers of the skin are still there and can grow back into a new mole.
To reduce the risk of a mole returning after removal, a person needs to follow the aftercare procedures recommended by their dermatologist. For example, the area where the mole was removed should be kept dry for at least 24 to 48 hours after surgery. Regularly change the bandage, wash the wound with soap, and limit sun exposure, according to Healthline.
