Melanoma and moles are distinguishable; firstly, moles are generally smaller, while melanomas have a larger diameter. Secondly, the color of a mole is more uniform, whereas the color of a melanoma is inconsistent in depth. Furthermore, moles are typically symmetric in shape, while melanomas are asymmetric. Lastly, melanoma is a type of malignant tumor, whereas a mole is simply a skin condition.

Is amputation useful for melanoma?

Melanoma is a very terrifying disease. Once melanoma develops on the limbs, there is a tendency to favor as extensive a surgery as possible. It seems that the larger the excision, the cleaner it becomes, which helps to prevent future recurrence and metastasis. Even undergoing amputation surgery doesn’t necessarily eliminate the risk of metastasis and recurrence. Sometimes, if the margins of the excision are not beyond the range, the risk still exists. Therefore, the extent of the excision should be determined based on the patient’s 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.

Is melanoma a malignant tumor?

Melanoma is a type of malignant tumor with a relatively high degree of malignancy and a high chance of metastasis, leading to a high mortality rate in the later stages. Once diagnosed, it is imperative to undergo surgical removal at a recognized hospital's dermatology department, followed by radiotherapy and chemotherapy. Melanomas usually develop from common melanocytic nevi, so if such nevi appear on the body, they should be treated correctly. If small, they can be removed with laser treatment; if slightly larger, surgical removal is recommended. If localized melanocytic nevi cause pain, itching, oozing, or bleeding, these could be precursors to malignant transformation and should be taken seriously.

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.

symptoms of melanoma bone metastasis

Once melanoma metastasizes, patients will experience significant pain, which will become increasingly severe and eventually unbearable. Having melanoma can also cause the bones to become brittle and prone to fractures and cracks. Once melanoma metastasizes, it also destroys the body's immune system, causing patients to suffer from long-term headaches and nausea, and making the body weaker.
