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.

Is there a possibility of curing melanoma with lymphatic metastasis?

Melanoma is a type of skin tumor caused by the excessive growth of melanin cells. For melanoma that has spread to the lymph nodes, surgical treatment is recommended, along with adjunctive radiotherapy and chemotherapy, which can effectively control the spread and metastasis of cancer cells. Traditional Chinese medicine can also be used in conjunction, which not only controls the growth of cancer cells but also mitigates the damage to the body from radiotherapy and chemotherapy. After treatment, patients should pay attention to their diet, exercise moderately, and maintain a good physical condition.

Melanoma CT manifestations

The CT manifestations of melanoma vary depending on the location of the tumor. Generally, melanomas that occur on the skin can appear on CT scans as mass-like lesions, and the scans can show whether there are any urgent conditions involving the surrounding nerves, blood vessels, and tissues. Some patients may only show CT imaging changes such as localized thickening of the skin. In melanomas that occur inside the skull or in the vulva, the CT mainly shows localized mass-like lesions. These lesions are typically low-density foci with poor blood supply around them, and they generally have an irregular shape.

Melanoma is divided into several types.

Melanoma is a type of malignant tumor with a relatively high level of malignancy. The exact causes of melanoma are not very clear but may be related to multiple factors including genetics, irritation, viral infection, and immunity. Generally, there are four types of melanoma: nodular melanoma, superficial spreading melanoma, acral lentiginous melanoma, and lentigo maligna melanoma. Once melanoma occurs, it is crucial to seek prompt medical diagnosis and treatment.

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.

Melanoma originates from which tissue?

Melanoma does not originate from any specific tissue, but from melanocytes. Therefore, melanoma can occur in any tissue where melanocytes are present. The most common sites for melanoma are the skin and mucous membranes. Additionally, because melanocytes are widely present throughout the body, melanoma can also occur in hollow organs such as the gastrointestinal tract, in skeletal muscles, and in the nervous system. Once diagnosed, melanoma needs to be treated promptly. The main treatments include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy.
