Regular mole examination by a dermatologist is key for maintaining skin health and skin cancer prevention, including melanoma, the most dangerous form of skin cancer. Moles, or nevi, are benign formations that appear on the skin due to pigment build-up, and the majority of them are harmless. However, certain moles can change shape, size, or colour over time, which can be a sign of malignancy. This is why it is important to monitor skin changes and visit a dermatologist regularly, in order to catch potentially dangerous changes in time.

Examination of a mole entails several key elements. A dermatologist uses a dermatoscope, a specialized instrument that allows them a detailed view of the mole’s structure, which facilitates the recognition of any signs of malignant changes. Additionally, the dermatologist carefully analyses all moles on the body, including the ones in hard-to-reach spots such as the scalp or between toes, which are often overlooked.

It is recommended that people with a lot of moles schedule regular screenings, especially if they have a family history of skin cancer. Special care is also recommended for people with fairer skin who like to tan or have experienced sunburn. It is recommended to undergo a dermatological exam once a year, or more frequently depending on the risk factors and specific conditions of a patient.

One important criterion for recognizing suspicious moles is the so-called "ABCDE" rule. This rule entails paying attention to the asymmetry of the mole, irregular borders, colour changes, size increases, and any bleeding or itchiness. If any of these changes are noticed, make an immediate appointment with a dermatologist.

The ABCDE rule:

A for asymmetry: One half of the mole does not match the other half.

B for border: Borders of the mole are uneven, irregular, or indistinct.

C for colour: The mole has several colours or an uneven pigmentation.

D for diameter: The mole is over 6 mm wide.

E for evolution: The size, shape, or colour of the mole has changed over time.

If you notice any of these signs, make an immediate appointment with a dermatologist.

Self-examination of the skin should be done regularly, approximately once a month. Start by checking your entire body, including your back, arms, legs, palms, soles of your feet, between your toes, and scalp, using a mirror for hard-to-reach areas. Use a second mirror to check your back and neck.

Regular mole examination not only means recognizing potential problems but also educating patients about the proper way to protect themselves from the sun, as well as performing skin self examinations that should be done between dermatological check-ups.

Proper sun protection includes protection from the sun through clothing and sunscreen with SPF 30+ broad-spectrum (UVA and UVB) applied 30 minutes before going outside, and reapplied every two hours and after swimming in the sea. Exposure to the sun between 9am and 5pm should also be avoided. Do not use tanning beds! Monitor the UV index and plan your activities accordingly.

In conclusion, regular mole examinations by a dermatologist play a key role in the prevention of skin cancer and allow for timely action in case of any changes.

Prevention is the best way to maintain skin health and prevent the development of serious diseases.
