Melanoma is a very serious disease, and if detected in its early stages, treatment should be sought promptly. If treatment is delayed, the effects of treating the disease in its advanced stages are not very good or significant. Melanoma is a type of malignant tumor that is prone to occurrence and poses a significant risk, endangering life. Generally, if melanoma is being tested, the Vacca double PAP immunoenzymatic marking method is used for detection.

What is melanoma?

Melanoma, also known as malignant melanoma, originates from the malignant transformation of melanocytes. It is commonly found in individuals with fair skin, blond or red hair, and blue eyes, who are often prone to this type of disease, particularly in tropical regions where the condition is more prevalent. The incidence rate increases after the age of fifty, and the rate of occurrence between men and women within the same group is quite similar. In a minority of cases, melanoma can also occur in parts outside of the skin, such as the anus, rectum, esophagus, or inside the eyes. When the tumor is confined within the epidermis, referred to as in situ carcinoma, it can be cured through surgery. If there is metastasis, treatment may include immunotherapy, chemotherapy, or local radiotherapy.

Melanoma cancer symptoms

Once melanoma begins to transform cancerously, the tumor will gradually grow larger, and the melanocytic nevi on the skin will also exhibit unusual phenomena. If various colors or a deepening of color appears in the melanin on a patient's body, it might indicate the onset of malignant changes. If a patient develops melanoma, it is advisable for them to seek medical attention promptly for surgical treatment, as this can help prevent the progression to cancer.

Is melanoma flat or raised?

Melanoma is generally raised and does not have a fixed shape. In the early stages of local growth, melanoma appears flat. As the tumor grows and proliferates, some protrusions may occur, but protrusions should not be equated with malignancy. If a previously flat mole suddenly becomes raised, one should be vigilant about the possibility of malignancy. However, a raised mole is not necessarily melanoma; there are some intradermal nevi or benign skin lesions, and other types of skin cancers can also manifest as raised changes. Therefore, if there are some melanocytic nevi on the skin that quickly develop symptoms such as ulceration, bleeding, pain, or itching, it is important to promptly visit a dermatology department at a standard hospital for an examination and, if necessary, surgical removal and pathological investigation.

How to diagnose melanoma

For the judgment of melanoma as a malignant tumor, it cannot solely rely on clinical experience. Instead, the skin lesion should undergo surgical excision. During the surgery, freezing can be scheduled, and the results of the freezing report will determine the scope of the surgery. The final diagnosis still depends on the paraffin section. The diagnostic gold standard is based on the pathological results, and only a pathology examination can determine whether the lesion is a malignant melanoma. Diagnosing such diseases requires extreme caution due to their high malignancy and ease of metastasis, which can endanger life. Standardized surgical excision is necessary, supplemented by chemotherapy and other methods.

Does melanoma develop quickly?

If melanoma is diagnosed, this disease must not be taken lightly. It is crucial to seek timely medical treatment and not miss the optimal treatment window, thus avoiding serious consequences. The progression of melanoma is very rapid, so once detected, it should be treated as soon as possible. This approach helps to control the spread of the disease and reduce further damage to the body. Melanoma easily causes pigmentation of the skin and can lead to localized breakdown and bleeding. Generally, if the treatment is not timely, ulcers and satellite lesions may develop, thus having a greater impact. Melanoma is also a disease that tends to metastasize easily. Patients may experience nausea, vomiting, affected appetite, weakness in the limbs, and it can also affect the liver, lungs, brain, and bones, causing symptoms including bone pain. Therefore, it is imperative to detect and treat this disease early to improve the body's healing rate.
