Skin cancer is the most diagnosed disease in the world. It is important to detect skin cancer as early as possible. The skin is the body’s largest organ, and has various functions. It provides protection against damage, potential microorganisms that can be deadly to the body. The skin, among other things, regulates body temperature.
There are several factors that affect the onset of skin cancer, such as UV radiation. UV rays cause mutations in the DNA of skin cells, thus modifying the genetic composition and transforming it into malignant cells . Skin cancer is most common in fair-skinned people.
How to detect skin cancer
Basal cell carcinoma
This is the most common form of cancer. It usually appears on the face, forehead or nose. Some people may be at increased risk due to genetic predisposition. UV light and exposure to certain chemicals such as arsenic also affect attacks on skin cancer cells.
Squamous cell carcinoma
This form of cancer usually occurs in areas of the body that are exposed to direct sunlight, since UV rays can easily affect the skin. However, there is no guarantee that this type of cancer will appear only in these areas. At an early stage, squamous cell carcinoma appears as a red mark that may resemble a wart. This type of cancer usually only affects the area where it occurs, since it lies deeper in the tissue that surrounds it. There is a possibility that it will spread, penetrate high-risk areas and lead to death.
It is a type of cancer that develops from pigment cells, called melanocytes. It usually appears as a dark spot. This is due to increased melanin, produced by cells that darken the skin and can lead to black or brown spots on the skin. Mole cancer is the leading cause of death from skin cancer. It usually occurs in fair-skinned people (Caucasians). 165,000 cases of mole cancer are detected each year worldwide, of which 48,000 are fatal. These cells are generally very invasive because they have the ability to spread throughout the body. Other organs that can be affected are the intestines and eyes. Melanoma is responsible for 75% of fatal cases.
The most influential factor for melanoma is exposure to sunlight . Solarium is another factor when it comes to preventing skin cancer. There are skin care treatments that, if performed regularly, can prevent skin cancer.
Recommendations for preventing skin cancer
There are risk factors for people who are often in direct contact with sunlight, and they should take extra precautions. With a view to preventing a possible skin cancer, it is recommended that you use the following when exposed to sunlight:
People over the age of 50 with fair skin and blue eyes should be more vigilant, as there is a greater risk of being exposed to this disease.
Some of the factors that can trigger skin cancer:
- Excessive exposure to natural or artificial light. We must avoid UV rays, but these can be filtered with sunscreen
- Light colored or blue eyes
- Genetic changes associated with this type of cancer
- Weakened immune system
- Exposure to arsenic
- Exposure to high radiation
Remember: always use sunscreen and be careful, it is important to detect skin cancer early!
