How fast nodular melanoma grow

Because thicker melanomas and NMs were associated with rapid tumor growth in the present study, we may be able to explain why rapidly growing melanomas were not associated with large numbers of nevi. Another important finding of this study is that rapid tumor growth is associated with atypical clinical features, including amelanosis, symmetry, border regularity, elevation, and the presence of symptoms.

These features have already been described for NMs 25 but are likely to be shared by any area of rapid expansile proliferation, whether it occurs de novo, as in an NM, or supervenes on a preexisting radial growth phase.

In summary, this study provides descriptive data on the spectrum of melanoma ROGs and insights into subgroups of patients with melanoma that are associated with rapid growth.

We propose that this information on melanoma ROG be incorporated into education programs for patients and health professionals. Special attention should be given to the promotion of awareness of the clinical characteristics of rapidly growing melanomas, such as symmetry, elevation, amelanosis, border regularity, and symptoms.

Lack of awareness of the features associated with rapidly growing melanomas among health care practitioners frequently leads them to inappropriately reassure patients about their lesions.

The penalty associated with diagnostic delay is particularly severe with a rapidly growing melanoma. Awareness of these lesions among health care practitioners should lead to expedited treatment rather than potentially catastrophic delay. Patients who develop aggressive tumors seem to lack the most important risk factors for melanoma, particularly the presence of a large number of nevi and freckles.

The lack of these risk factors makes it more difficult for the physician to identify a lesion with atypical clinical features as a melanoma. We propose that further education programs target early detection and accelerated management of the most aggressive melanomas. Further research is required to investigate the clinical, histologic, epidemiologic, and molecular associations of rapidly growing melanomas.

Melanomas are more likely to be asymmetrical when compared to a normal mole. A mole has smooth edges and clearly defined borders. Cancerous moles may have fuzzy borders and notched or scalloped edges. Abnormal coloring of a mole is definitely a reason for concern.

Most nodular melanomas will appear as a blackish-blue or reddish-blue bump. However, some nodules have no color or are flesh-toned. Flesh-toned nodules are called amelanotic nodules. These melanoma spots appear as the same color as the surrounding skin because the nodule lacks pigment. Amelanotic nodules occur in about 5 percent of nodular melanoma cases.

If the skin lesion is larger than 6 millimeters in diameter or growing, it may be a sign of melanoma. Some skin cancers begin as bumps or thick spots on your skin. As its name suggests, a nodule, or a dome-shaped growth on the skin, is the primary characteristic of nodular melanoma. Increased elevation of the skin bump is a warning sign for melanoma, particularly for nodular melanoma, and should be a red flag that something may be wrong. Moles and birthmarks that rise above the skin are typically limp or give easily when pressed.

Nodular melanomas are not. Instead, these melanoma sites are often very firm to the touch, not giving or moving when pressured with a finger. Press the site that concerns you with your finger. If you feel a hard knot, ask your doctor to look at the growth. New freckles or moles typically develop and stop growing within a few weeks. New developments that continue to grow after two or three weeks may be melanoma. The most common growth sites for nodular melanoma are the neck, head, and the trunk of the body.

Unlike some other types of skin cancer, nodular melanomas typically begin as a new growth, rather than developing within a pre-existing mole. It can take as little as three months for these types of cancer to spread internally. Nodular melanoma can quickly jump to advanced stages.

That is part of what makes this type of skin cancer so deadly. Advanced stages of nodular melanoma are difficult to successfully treat. Early stages of melanoma are treated by using surgery to remove the melanoma and some of the healthy skin surrounding the melanoma. Your doctor may also recommend a lymph node biopsy so they can see if any cancer cells have spread to your lymph nodes.

Melanoma that has spread to lymph nodes or internal organs requires other treatment methods, such as:. Melanoma becomes more difficult to treat and cure once it has begun to spread internally. Learn more about melanoma risk factors. But there are other signs of melanoma to be aware of. Learn more about how to identify melanoma. Nodular melanoma is highly curable when diagnosed early. However, because nodular melanoma grows so quickly, it is often found at a more advanced stage.

The goals for treatment of nodular melanoma are to:. The extent and depth of the melanoma guides your care plan. Treatment often involves surgery to remove the melanoma. If the melanoma is more advanced and has spread to other parts of the body, such as the lymph nodes or internal organs, then immunotherapy, targeted therapy, chemotherapy, radiation, surgery, or a combination of therapies may be used to shrink the tumor.
