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.

Is melanoma cancer?

Melanoma is generally a malignant tumor caused by melanin in the skin and other organs, which means melanoma is also known as cancer, and it is a very bad tumor. If there are hair follicles in this melanoma, then it is very likely that cancerous changes will occur. Patients should pay attention as the malignancy of the disease is extremely high, and they should seek timely medical examinations and treatment.

Can melanoma without metastasis avoid chemotherapy?

For patients with melanoma that has not metastasized, direct surgical removal can be performed, and chemotherapy is not necessary after surgery. Melanoma is a malignant tumor that originates from melanocytes and can occur in many parts of the body, with melanomas of the skin and mucous membranes being the most common, accounting for about 70% of all cases. Once melanoma is diagnosed, if there is no distant metastasis to other organs, curative surgical removal can be performed. Postoperative treatment mainly involves immunotherapy, not systemic chemotherapy. For patients who are diagnosed with distant organ metastasis, systemic chemotherapy and immunotherapy are required.

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 check what items

If patients suspect that they have melanoma, they must go to a qualified hospital for examination. The diagnosis of melanoma mainly relies on visual inspection of colored moles that vary in color and shape, which can be directly observed with the eye. Also, if previously existing moles have enlarged or changed shape recently, these are signs that we need to pay attention to. If patients are suspected of having melanoma after a diagnosis, it is recommended to perform a complete excisional biopsy of the lesion, followed by a pathological examination after the surgery.

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.
