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.

Melanoma stage IV is the fourth stage.

Melanoma stage IV refers to the fourth stage of melanoma, where IV represents the Roman numeral for 4. Stage IV melanoma means that the melanoma is no longer confined to the local lesion but has metastasized to distant organs. The most common locations for melanoma include the skin and mucous membranes, with typical metastatic sites including the lungs, brain, liver, etc. Once diagnosed as stage IV, there are no indications for surgical treatment. Treatment primarily involves a comprehensive approach combining chemotherapy, radiotherapy, targeted therapy, and immunotherapy.

Is melanoma easy to get?

Melanoma is not easy to contract, with relatively low incidence and mortality rates. Melanoma is a tumor derived from the malignant transformation of melanocytes, highly malignant, often occurring in the skin but also in mucous membranes, the choroid of the eye, the pia mater, and other various parts and tissues. In the Chinese population, it commonly appears on the extremities of the skin, such as the sole of the foot, toes, fingertips, and under the nails. According to global cancer statistics from last year, melanoma accounts for 1.6% of all new cancer cases. In China, the incidence and mortality rates of cutaneous melanoma are relatively low, with about one case per 300,000 people. In recent years, there has been a rapid increase in the incidence of melanoma, which needs to be monitored carefully.

What are some good methods for treating widespread metastasis of melanoma?

Melanoma greatly torments patients, affecting their physical and mental health, and also unnecessarily harming their external appearance. However, treatment of this disease must be approached with caution. Surgical excision is recommended and is the first choice for the surgical treatment of melanoma. If diagnosed, surgery should be carried out promptly. The extent of excision depends on the type and location of the tumor. After excision, the resulting tissue defect is generally repaired using simple methods initially, followed by reconstructive surgery after confirming no recurrence.

What are the symptoms of subungual melanoma?

Subungual melanoma, clinically, displays different symptoms depending on the stage. In its early stages, subungual melanoma primarily manifests as changes in nail color, with some cases showing localized thickening of the nail. As the melanoma progresses, abnormal secretions such as bloody or serous fluids may appear under the nail, and the nail itself may become uneven. As the subungual melanoma invades surrounding tissues, symptoms such as swelling, pain, or bleeding in the localized fingernail may occur. In advanced stages, symptoms of metastatic sites, such as coughing, chest pain, and chest tightness from lung metastases, can also manifest.

How long does it take for melanoma to develop?

The duration of melanoma development varies because melanoma is a type of skin cancer with a relatively high degree of malignancy. However, clinically, the types of melanoma are diverse, and the onset time generally correlates with the patient's clinical phenotype. For some superficial types of melanoma with low malignancy, it generally takes several years to develop. For highly malignant melanomas, the disease generally progresses rapidly within about six months to a year. Once melanoma progresses, it can affect multiple parts of the body and severely impact the patient's lifespan.
