An atypical mole is a mole that has a clinical and histological appearance that is slightly different from that of other common moles (structural disorders and melanoma cell abnormalities). The article will help readers better understand what atypical moles are, and how they are related to skin cancer.1. What is an atypical mole?
Atypical moles are benign melanocytes with irregular and indistinct margins.The color of moles is irregular, varied, often brown and tan, forming patches or papules. Patients with atypical moles are at increased risk for melanoma.
2. Manifestations of atypical moles
Moles are usually more aggressive than other moles (> 6 mm in diameter)Round in shape (unlike melanoma) but have indistinct borders and slight asymmetry.
However, an abnormal mole does not necessarily mean it is cancerous.
3. Manifestations of melanoma
With melanoma, the mole will be irregular in color, large, and may have red, blue, white, hyperpigmented areas or alternate with a scar. Non-circular moles Larger than 6mm in diameter Growing other moles or old moles on the body that change size quickly How can a doctor tell if a mole is cancerous ?Visual inspection only detects moles that may be cancerous, but cannot determine with certainty whether it is or not.
The only way to diagnose the condition is to order a biopsy. If the doctor thinks there is a problem with the mole, the doctor will take a sample by injecting a local anesthetic, then scrape as many moles as possible.
Then send the specimen to a laboratory, where the pathologist will examine the cancer cells under a microscope.
