I would have adviced lymph node biopsy
Detailed Answer:
Hi. Thanks for posting your concern at HCM
Melanoma is less common than other skin cancers. However, it is much more XXXXXXX if it is not found early.
If melanoma is found early, while it is still small and thin, and if it is completely removed, then the chance of cure is high.
Early signs of melanoma are changes to the shape or color of existing
moles. At later stages, the mole may itch, ulcerate or bleed. Early signs of melanoma are summarized by the mnemonic "ABCDE":
--Asymmetry
--Borders (irregular)
--Color (variegated)
--Diameter greater than 6 mm (0.24 in): Diameter is the weakest sign in this system is the diameter. Many melanomas present themselves as lesions smaller than 6 mm in diameter; and all melanomas are malignant on day 1 of growth, which is merely a dot
--Evolving over time
Five year survival rates depend on the size, lymph node involvement and presence or absence of distant metastasis (TNM Staging). It is not dependent on the number of melanomas and site of melanomas.
Size of the Melanoma is a favorable one in your case e.g a
tumor ≤ 1.0 mm without ulceration; no lymph node involvement; no distant metastases has >95% five year survival rate as compared to a tumor > 4.0 mm without ulceration; no lymph node involvement; no distant metastases, which has 63%-67% five year survival rate.
Lymph node involvement does lowers the five year survival to 30%-59%, thus even i would advice a biopsy from the
enlarged lymph node no matter how less likely it is to be due to Melanoma.
Hope this helps you
take care
