Squamous cell carcinoma is the second most common skin cancer and also one of those with the best prognosis when detected early. I will explain to you, without alarmism, how it develops from a precancerous lesion, what makes it more or less aggressive, how to recognize it, and what treatment corresponds to each case.
When an actinic keratosis appears, it is almost never alone: around it is a whole field of cancerization, photodamaged skin with invisible lesions. I will explain what it is, why it matters for the risk of squamous cell carcinoma, and how field treatments compare based on two objectives: clearing lesions and preventing cancer.
Basal cell carcinoma is the most common skin cancer and also has the best prognosis: it is almost always cured with simple surgery. I will explain its 6 variations, without causing alarm, how it is diagnosed with dermatoscopy, and what treatment corresponds to each.
Most itchy moles are benign. But itching can also be a sign to take seriously under certain circumstances. I'll explain when an itchy mole warrants a consultation and when you can relax, with a real clinical case from my practice and the ABCDE-I rule.
The gut microbiota accompanies melanoma in all its stages: risk, tumor prognosis, and response to immunotherapy. I will explain what current science says and what you can do at home (diet, fiber, exercise), without alarmism or overpromising. An evidence-based guide from a dermatologist specializing in melanoma at the Hospital Clínic.
If you have been diagnosed with melanoma and your medical team has told you about immunotherapy, it is normal to have questions. I explain what it is, when it is used (neoadjuvant, adjuvant, advanced melanoma), what types exist and what side effects to expect. Information based on the most current scientific evidence.
Are apps useful for checking moles? As a dermatologist researching artificial intelligence applied to melanoma, I analyze with data the reliability of SkinVision, FotoSkin and other apps. I explain what they can do, what they can't do, and when you should go to the dermatologist.
Actinic cheilitis is a premalignant lesion of the lip that affects 31% of people over 45 years of age in Spain. I explain how to recognize it, the available treatments (with success rates of up to 97%), and how to prevent it with lip sun protection.
Photodynamic Therapy (PDT) is an effective and minimally invasive treatment for actinic keratosis, basal cell carcinoma and photoaging, preserving healthy tissue. Its application with LED or daylight allows it to be adapted to each patient, offering excellent aesthetic results. In my practice in Barcelona, I use fractionated CO2 laser to enhance drug absorption and improve treatment efficacy.
A cutaneous horn is a rare dermatological lesion that typically appears as a bump on the skin composed of keratin. While its appearance may be startling, it is important to understand that, in many cases, a cutaneous horn can be associated with benign, precancerous, or even malignant conditions. In this article, I explain what it is, why it forms, and how it is treated, so you can learn more about this condition and its relevance to skin care.
