Cancerous moles are actually a type of skin cancer called melanoma. Melanoma is a tumor that originates from pigment cells (melanocytes) and can grow very quickly. If it is not diagnosed early and treated appropriately, it can spread to other parts of the body.

Melanomas usually develop from irregularly shaped, colored and large-sized moles. However, not every large, irregular or colored mole is melanoma. Therefore, it is extremely important to regularly check the moles on our skin and to consult a dermatologist immediately if any changes are noticed.
Symptoms of Cancerous Moles
The most important symptoms of cancerous moles are:
1. Size: The diameter of the mole is larger than 6 millimeters (about the size of a pencil head).
2. Shape: The mole has an irregular, asymmetrical shape.
3. Edge: Irregularity and messiness at the edges of the mole.
4. Color: The color of the mole is not homogeneous, it is in different tones.
5. Change: Changes in the size, shape, color or other characteristics of the mole.
If you notice any of these features in a mole on your skin, it is important to see a dermatologist immediately.
Diagnosis of Cancerous Moles
The most effective method for diagnosing cancerous moles is an imaging technique called dermoscopy. Dermoscopy allows a close examination of the structure and characteristics of the mole. Your dermatologist will evaluate the mole in detail with this method and, if necessary, perform a biopsy (tissue sampling) procedure to make a definitive diagnosis.
In addition, thanks to the developing technologies in recent years, mobile phone cameras have also begun to be used in the diagnosis of cancerous moles. Some mobile applications can analyze mole pictures taken with a mobile phone camera and provide preliminary information about the mole's cancer risk. However, these applications are not sufficient to make a definitive diagnosis. It is absolutely necessary to see a dermatologist.
Can Cancerous Moles Be Understood with Pictures?
Pictures can play an important role in the diagnosis of cancerous moles. In particular, thanks to mobile phone cameras, you can take and record pictures of moles on your skin. Then, you can share these pictures with your dermatologist and learn about the structure and characteristics of the mole.
However, we should not forget that mole images alone are not enough to make a diagnosis. A dermatologist must examine the mole in person, perform advanced tests such as dermoscopy, and take a biopsy if necessary. Evaluations based solely on images may not provide definitive results. Therefore, it is important to regularly check the moles on your skin and consult a dermatologist immediately if you notice any changes. Early diagnosis is of great importance in the treatment of cancerous moles.
