With summer coming to our country, it is crucial to pay attention to our health and, in particular, to the health of our skin. Skin cancer is one of the most common forms of cancer, but it is also one of the most preventable. Here we offer you key information, statistics, signs and symptoms, and a prevention guide to help you enjoy the sun safely.

Skin Cancer Statistics

Skin cancer is a significant concern globally and in Mexico. According to the World Health Organization (WHO), around 3 million cases of non-melanoma skin cancer and 132,000 cases of melanoma are diagnosed worldwide each year. In Mexico, the incidence of skin cancer has been increasing, especially in areas with high sun exposure.

Risk factors

A risk factor is one that increases the likelihood of developing a disease.

According to the National Cancer Institute, some of the most common types of skin cancer are:

• Exposure to ultraviolet light: This is the main risk factor for most melanomas. Sunlight is the main source of radiation (UVA and UVB rays). Tanning beds are also sources of radiation.
• Moles: People with many moles are more likely to suffer from melanoma.
• Very fair skin, freckles and light hair: The risk is more than ten times higher in white people than in black people. People with blond or red hair, blue or green eyes and a tendency to have freckles are at greater risk of developing skin cancer.
• Sex: Men have a higher incidence rate than women.
• Age: Melanoma is one of the most common cancers in people under 30 years of age.
• Background: The risk is higher if a family member has had the disease. Those who have already had melanoma are at higher risk of developing it again.

Remember that a risk factor is not decisive and/or conditioning, therefore, it is very useful to follow the ABCDE rule to monitor your skin.

Skin Cancer Prevention Guide

Protecting your skin from the sun is the best way to prevent skin cancer. Here are some practical tips:

1. Use sunscreen: Apply a broad-spectrum sunscreen with an SPF of at least 30, even on cloudy days. Reapply every two hours and after swimming or sweating.
2. Dress appropriately: Wear long-sleeved clothing, hats, and sunglasses to protect your skin.
3. Avoid midday sun: UV radiation is most intense between 10 a.m. and 4 p.m. Try to find shade during these hours.
4. Perform regular self-exams: Check your skin regularly for any changes and see a dermatologist at least once a year.
5. Avoid tanning beds: Tanning beds significantly increase the risk of skin cancer.

Remember, taking care of your skin not only helps you prevent cancer, but also allows you to enjoy the summer safely and healthily.
