THESE are malignant skin tumors caused by abnormal cell growth. THEY can occur when the skin is exposed to the sun for a prolonged period of time without any protection. However, cancer can develop in unexposed areas. Following a diagnosis of skin cancer, there may be three types of cancer that are the most common: basal cell carcinoma, squamous cell carcinoma, and melanoma.
Signs and symptoms depend on the type of cancer. Basal cell carcinoma usually looks like a tumor with small blood vessels on the surface and has slow growth.
Whereas melanoma looks like a large, irregular mole that may bleed and has a very fast growth.
On the other hand, squamous cell carcinoma presents in the form of blisters or rough, red patches of skin. It is visible in areas such as the scalp, ears, mouth, and soles of the feet; and it may even be present in the genital area.
If you notice any abnormal growth on your skin, it is important to see a dermatologist. If the doctor considers that THERE IS A POSSIBITY of malignancy, a skin biopsy will be taken to confirm the diagnosis.
One of the most important risk factors for this type of cancer is exposure to ultraviolet radiation. Therefore, it is of utmost importance to use sunscreen and to cover ourselves with a hat, cap, sun sleeves for driving or clothing if we are going to be exposed to the sun. There are other methods to monitor and prevent cancer.
Unlike other types of cancer, early-stage skin cancer does not spread beyond the site where it is found. This is why the curative treatment is surgery without the need for chemotherapy or radiotherapy.
