How to prevent skin cancer and melanoma

Prevenir el cáncer de piel y el melanoma

The skin cancer, especially melanoma, is one of the most aggressive forms of this disease, but also one of the easiest to prevent if detected early. Do you know how to prevent skin cancer? Or what skin cancer spots look like and when to worry about them? On the occasion of the European Day for the Prevention of Skin Cancer, this post provides clear and practical guidance on how to avoid skin cancer, how to identify the first signs, and what you can do to protect your health starting today.

How to prevent skin cancer?

Skin cancer prevention relies on minimizing damage caused by ultraviolet radiation. Sun exposure, especially when it causes burns, is the main avoidable risk factor.

To prevent skin cancer and melanoma:

The best cream to prevent skin cancer is one that provides broad-spectrum sun protection, is water-resistant, and is reapplied every 2 hours.



What do skin cancer spots look like?

One of the most important signs to detect melanoma is to look for changes in moles. Pay attention to the following characteristics:

“A lesion that looks different from the others should be checked”

Skin cancer spots may appear as new lesions or result from changes in an existing mole. Monthly self-examination and knowing your skin well are essential to detect any suspicious change.

How do I know if I have skin cancer?

If you notice a lesion with the characteristics mentioned above, you should consult a dermatologist. Diagnosis is carried out using advanced technology:

In addition, at barnaclínic+ we have the Vectra 360, a 3D body mapping system that enables digital monitoring of all moles and melanocytic lesions, detecting subtle changes that may go unnoticed to the naked eye.

How to prevent skin cancer if I have risk factors?

Although anyone can develop melanoma, there are certain factors that significantly increase the risk. Being aware of them allows for stricter prevention measures and earlier consultation in case of warning signs.

Main skin cancer risk factors:

“We all have a risk of melanoma, including people with darker skin and eyes”

Dr. Susana Puig

Although the risk is higher for individuals with light skin types, people with darker skin can also develop skin cancer. In fact, in Catalonia and the rest of Spain, most cases occur in individuals with intermediate skin tones and dark eyes.

How to prevent skin cancer if you have any of these factors?

Awareness and taking action are key. Skin cancer prevention is not only possible, but can make a crucial difference between early diagnosis and advanced disease.

What is the treatment for melanoma?

Melanoma treatment depends on the stage at which it is diagnosed. In early stages, surgery is usually curative; however, more advanced cases may require additional treatments.

“Thanks to these new treatments, life expectancy for patients with advanced melanoma has improved significantly”

Dr. Susana Puig

Advances in immunotherapy and targeted therapies have radically changed the prognosis for metastatic melanoma, allowing many patients to live longer and with better quality of life.

In summary…

Dr. Susana Puig - dermatologist

“Melanoma is preventable. Avoiding UV radiation and knowing your skin are the best tools”

Dr. Susana Puig

At barnaclínic+, we encourage you to protect your skin year-round, schedule regular dermatology check-ups, and consult your specialist with any concerns. Skin cancer prevention is in your hands.
