JAKARTA - The skin is the largest body organ that has an important role in protecting the body from various external threats, ranging from exposure to sunlight to microorganisms.

Therefore, changes that appear on the skin, such as the appearance of unusual spots or spots, should not be underestimated.

Although most of these changes can be temporary and harmless, there are times when these conditions are an early symptom of a more serious disease.

Most red spots or small bumps will indeed fade by themselves. However, if the spots appear suddenly, they never disappear, accompanied by pain, swelling, or even fever, then it needs to be watched out for.

Professional medical treatment is highly recommended to ensure whether the condition is mild or instead indicates more serious health problems, such as skin cancer or other dermatological disorders.

Here are 4 serious skin conditions that can be characterized by the appearance of patches or striking changes to the skin, reported by the Verywell Health page.

1. Basal Cell Carcinoma (Basal Cell Carcinoma)

Basal cell carcinoma is the most common form of skin cancer. This disease develops slowly and usually arises due to exposure to ultraviolet (UV) rays from the sun in the long term. One of the most distinctive signs of skin cancer this type is the emergence of small white bumps resembling candles, or brown scaly spots in areas of the body that are often exposed to sunlight, such as face, neck, or arms.

Although its growth tends to be slow, basal cell carcinoma still needs to be treated to prevent further damage to skin tissue. Treatment generally involves Mohs' surgical procedure, which is a highly effective micro surgery technique to remove cancer tissue as a whole. In addition, treatment can also be done through the use of topical drugs or other conventional surgery, depending on the size and location of cancer.

2. Karonoma Sel Skuamosa (Squamous Cell Carcinoma)

Other types of skin cancer that also occurs quite often are squamosa cell carcinoma. This condition develops from squamosa cells found in the outermost layers of the skin. Symptoms can vary, ranging from hard red nodules, scaly flat wounds, to red patches that can appear not only in the skin, but also in the mukosa area such as the interior of the mouth, genitals, or anus.

Unlike basal cell carcinoma, scuamosa cell carcinoma has the potential to spread to other body tissues if not handled early. Therefore, early detection is very important to prevent further complications. Treatment can include surgery, radiation therapy, or special creams containing active anticancer ingredients.

3. Melanoma

Compared to the previous two types of skin cancer, melanoma is the most aggressive and high-risk type that causes death if not treated quickly. Melanoma usually starts from moles that experience suspicious changes, such as color change, non-symmetric shape, uneven edges, enlarged diameter, or itching and bleeding.

Symptoms of melanoma are often abbreviated with the ABCDE formula, namely: Asymmetry, Boundary (Border), Color (Color), Diameter, and Evolving (Development).Melanoma can spread quickly to other organs if not diagnosed early. Treatments performed depend on the stage of disease, can be in the form of surgery to remove tumors, radiation therapy, chemotherapy, or immunotherapy to increase body resistance against cancer cells.

4. Actinic Keratosis (Actinic Keratosis)

Actinic ratosis is a preinvasive skin condition caused by damage to sun exposure over a long period of time. This rickshaw usually looks rough, scaly, and resembles a small wart. The areas of the body that are most often affected are the most common parts exposed to the sun, such as face, facial skin (especially in bald men), neck, hands, and lower arms.

Although actinic ratosis is not cancer, this condition can develop into a carcinoma of squeez cells if left untreated. Therefore, regular medical supervision is very important. Treatment can include topical creams that lift abnormal skin cells, frozen therapy (cryotherapy), or laser ablation procedures.

Prevention efforts are no less important. Reducing direct exposure to UV rays, using high SPF sunscreen, and wearing protective clothing while in the sun are steps that can help reduce the risk of the emergence of actinic keratosis and other skin cancers.
