Not all atypical moles are precancerous, but they do have a higher risk of developing into melanoma than ordinary moles. However, it’s important to monitor any changes to these mole and have them examined by a dermatologist regularly.
How are atypical moles diagnosed?
Atypical moles can be diagnosed through a medical examination by a dermatologist or other healthcare provider. The diagnosis may also involve a skin biopsy in which a small sample of the mole is removed and examined under a microscope. Additional tests such as dermoscopy, digital mapping or total body photography may also be used to aid in the diagnosis and monitoring of atypical moles.
What is the difference between a typical mole and an atypical mole?
A typical mole is usually circular or oval-shaped and has a uniform color with distinct edges. An atypical mole, also called dysplastic nevi, on the other hand, can have varying colors, shape, and texture. Atypical moles may exhibit asymmetry, irregular borders or jagged edges, variation in color and diameter greater than 6mm. Additionally, atypical moles have cells that appear abnormal when examined under a microscope and are generally larger than normal moles. While both types of moles can increase the risk of developing skin cancer if they appear in large numbers or if they undergo changes over time; atypical moles tend to have an increased risk for certain types of skin cancers compared to typical ones.
How do doctors determine if an atypical mole is cancerous or not?
To determine if an atypical mole is cancerous, doctors usually perform a biopsy. During this procedure, the doctor will remove a sample of the suspicious mole and send it to a laboratory for analysis. The pathologist will then examine the cells under a microscope to check for signs of cancer or other abnormalities. In some cases, the doctor may also use dermoscopy, which is a specialized tool that allows them to examine the mole in greater detail and identify any irregularities that might not be visible to the naked eye. Additionally, doctors may consider other factors such as family history and previous biopsies when making their diagnosis.
What is the likelihood that an atypical mole will become cancerous?
Atypical moles, also known as dysplastic nevi, have a higher risk of developing into melanoma than common moles. However, not all atypical moles will become cancerous. The likelihood depends on individual factors such as the size and number of atypical moles someone has, family history of skin cancer, and overall sun exposure. It’s recommended to have any changing or suspicious mole checked by a dermatologist.
What are the treatment options for precancerous moles?
The treatment options for precancerous moles depend on their size and location. The most common way to treat precancerous moles is by surgical excision, in which the entire mole is removed along with a small margin of healthy skin tissue. Other treatment options include cryotherapy, radiation therapy, or topical chemotherapy. It’s important to consult a dermatologist who can evaluate the specific case and recommend the best treatment option.
