Life After Treatment
If Melanoma Recurs
The probability that melanoma will recur after appropriate treatment is characterized as low-risk, intermediate-risk, or high-risk.
The risk of recurrence increases with:
If you have had melanoma in the past, you are at increased risk for recurrence. A significant number of patients with a past history of melanoma develop a second primary tumor after a period of time. A study reviewing the data of 3310 patients with Stage I and Stage II melanoma revealed a 2.8% risk of developing a second melanoma after 5 years, and a 3.6% risk after 10 years.1 Therefore, screening for melanoma recurrence through skin self-examination and regular medical skin examinations is of the utmost importance.
The appearance of a second melanoma does not necessarily carry a poor prognosis, particularly when the recurrence is local and found in an early stage. Research supports the benefits of close physician follow-up and patient education in the early detection of second melanomas. In one study, the thickness of a second primary melanoma was compared to that of the initial primary tumor. In almost 50% of cases, the second melanoma was significantly thinner than the initial melanoma.2 With earlier diagnosis, these thinner, second melanomas can be treated with simple tumor surgery and carry an encouraging prognosis for long-term survival.References
