This collects unwanted particles and infectious organisms. When melanoma spreads through the lymphatic system, cancer cells may settle in lymph nodes around the neck, in the armpits or in the groin. The lymph nodes catch foreign or harmful substances such as bacteria and cancer cells. When this happens the nodes can become swollen and tender to touch. Haematogenous spread is when melanoma spreads into the blood stream.
Once in the blood stream, melanoma cells can travel around the body. The cells can settle anywhere and start growing. The new growths of metastatic melanoma can make you very sick. Melanoma often grows in the lungs, the liver and brain.
Melanoma may also grow in bone, heart, pancreas, adrenal glands , digestive tract, spleen, kidneys and thyroid glands. The outlook of metastatic melanoma is poor, especially if there is nodal metastasis and haematogenous spread to internal organs.

Melanoma tumors that have metastasized to other parts of the body are still considered melanoma. For example, melanoma found in the lungs is called metastatic melanoma of the lung or melanoma with lung metastases. Major risk factors for melanomas include:. Other factors have been connected with increased metastasis.
In a study in the Anais Brasileiros de Dermatologia and a study in the Journal of the National Cancer Institute , the following factors were associated with higher levels of metastasis:.
This is especially important for those with many risk factors. Melanoma is more treatable at early stages, so early identification may prevent metastatic melanoma from developing.
For this, a small section of suspected cancerous skin is removed with a razor, scalpel or small punch tool. To test for metastatic melanoma, or melanoma that has spread to lymph nodes or distant parts of the body, your care team may perform the following tests. Your melanoma is given a stage depending on how much the cancer has progressed upon diagnosis.
Stages 0, 1 and 2 are melanoma. Stage 3 some cases and stage 4 melanomas are considered metastatic melanomas. This cancer can be any thickness and may or may not have spread to nearby lymph nodes. Metastatic melanomas can be difficult to treat. The five-year survival rate for people diagnosed with melanoma that has spread to nearby lymph nodes is 66 percent, according to the American Cancer Society.
When cancer has spread to distant parts of the body, there may also be other metastases too small to detect by scans. For people diagnosed with stage 4 melanoma, or melanoma that has spread to distant parts of the body, the five-year survival rate is 27 percent.
Multiple therapies can be used at any given time, and your care plan is a dynamic process. You and your care team should discuss all the options and decide on a treatment plan.
Other medications and options may help manage the symptoms of your cancer treatment, so you can live the highest quality of life possible throughout the course of your treatment and disease.
