What is the most common type of melanoma?

Superficial spreading melanoma is the most common type of melanoma skin cancer. It makes up about 70% of all melanoma skin cancers.

What is the most aggressive type of melanoma?

Nodular melanoma – This is the most aggressive form of cutaneous melanoma.

Which type of melanoma has the best overall prognosis?

Nodular melanoma had the lowest melanoma-specific survival, while superficial spreading or lentigo maligna had the best prognosis among histological subtypes. However, differences in melanoma survival in different sex and age groups, localizations and histological types were not statistically significant.

What are the four types of melanoma?

What are the Types of Melanoma?

  • Melanoma is a type of cancer that develops in the melanocytes—the cells in our skin that produce pigment. …
  • There are four main subtypes of cutaneous melanoma: superficial spreading; nodular; lentigo maligna; and acral lentiginous.

How common is superficial spreading melanoma?

Superficial spreading melanoma is the most common type of melanoma, accounting for around 70 percent of all cases. It starts growing along the top layer of the skin. Over time it penetrates deeper into the skin. This cancer can occur in adults of all ages.

Is nodular melanoma a death sentence?

Nodular melanoma tends to spread rapidly and eventually metastasize to vital organs. It may be fatal within months of recognition.

Which is worse melanoma or carcinoma?

Melanomas are generally much more dangerous than carcinomas. Early detection helps with treatment in both cases and can be a key to dealing with the problem.

Where is melanoma most common?

In women, the legs are the most common site. Other common sites are the neck and face. Children can also develop melanoma. In 2021, an estimated 207,390 cases of melanoma will be diagnosed in the United States.

How long does it take for melanoma to metastasize?

214 patients with MM were evaluated retrospectively. Distant metastases (82%) were the most frequent for patients initially metastatic. The median and 1-year survival rates of initially MM patients were 10 months and 41%, respectively. The median time to metastasis for patients with localized disease was 28 months.

Is Stage 1 melanoma serious?

Prognosis for Stage 1 Melanoma: With appropriate treatment, Stage I melanoma is highly curable. There is low risk for recurrence or metastasis. The 5-year survival rate as of 2018 for local melanoma, including Stage I, is 98.4%.

Is there a difference between melanoma and malignant melanoma?

Melanoma is a cancer that begins in the melanocytes. Other names for this cancer include malignant melanoma and cutaneous melanoma. Most melanoma cells still make melanin, so melanoma tumors are usually brown or black.

Is there more than one kind of melanoma?

There are four main types of skin melanoma. Superficial spreading melanoma is the most common type of melanoma.

Is melanoma always malignant?

While malignant, these are unlikely to spread to other parts of the body if treated early. They may be locally disfiguring if not treated early. A small but significant number of skin cancers are malignant melanomas. Malignant melanoma is a highly aggressive cancer that tends to spread to other parts of the body.

Can melanoma stay in situ forever?

Melanoma in situ can be cured if it is cut out (excised) completely. However, if not removed with appropriate surgery, it can develop into an invasive cancer.

Can melanoma stay in situ for years?

The basic tumour staging of melanoma includes five stages, stage 0 (in situ) to stage IV. The survival rates based on this staging system are listed in Table 2 and the main types of melanoma are listed in Table 3. In general, the prognosis deteriorates from the in situ stage (stage 0) to stage IV.

Can melanoma be smaller than 6mm?

Melanomas are often larger than 6 mm (1/4 inch) in diameter. However, with increased awareness about early detection, about 30% of melanomas are found when they are less than 6 mm in diameter.
