What is the prognosis for melanoma in situ?
Prognosis: Stage 0 melanoma, or melanoma in situ, is highly curable. There is very little risk for recurrence or metastasis. The 5-year survival rate as of 2018 for local melanoma, including Stage 0, is 98.4%.
How long does acral melanoma stay in situ?
[4], the duration of ALM in situ ranged from 5 to 30 years and none progressed to invasive melanoma for the follow up period.
Is melanoma in situ the same as Stage 1?
Stage I Melanoma This is a noninvasive stage, which is also called melanoma “in situ,” meaning “in its original place.” With stage I melanoma, the tumor’s thickness is 1mm or less. This tumor may or may not have ulcerated, and it isn’t yet believed to have spread beyond the original site.
Does melanoma in situ always progress?
In situ melanomas don’t spread to other parts of the body or cause death, but if the tumor has an opportunity to grow even one millimeter deep into the skin, it can lead to more involved treatment and greater danger. If left untreated, it can metastasize and even become life-threatening.
Is Stage 1 melanoma curable?
Learn more about melanoma treatments here. 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%.
How long does melanoma in situ take to spread?
The lesion can grow slowly for 5 to 15 years in the in situ form before becoming invasive. The exact percentage of lentigo maligna lesions that progress to invasive lentigo maligna melanoma is unknown but is estimated to be less than 30% to 50%.
How is Stage 0 melanoma treated?
Stage 0 melanoma (melanoma in situ) has not grown deeper than the top layer of the skin (the epidermis). It is usually treated by surgery (wide excision) to remove the melanoma and a small margin of normal skin around it. The removed sample is then sent to a lab to be looked at with a microscope.
Does melanoma in situ spread?
Can melanoma in situ spread?
How serious is melanoma in situ?
Can melanoma in situ become invasive?
Stage 0 melanoma is not considered invasive melanoma; the other stages (I, II, III, and IV) are invasive. In Stage 0 melanoma, there is no evidence the cancer has spread to the lymph nodes or to distant sites (metastasis). Stage 0 is local melanoma, meaning it has not spread beyond the primary tumor.
Does Stage 0 melanoma spread?
In Stage 0 melanoma, there is no evidence the cancer has spread to the lymph nodes or to distant sites (metastasis). Stage 0 is local melanoma, meaning it has not spread beyond the primary tumor.
What is the best treatment for melanoma in situ?
Stage 0 melanoma (melanoma in situ) has not grown deeper than the top layer of the skin (the epidermis). It is usually treated by surgery (wide excision) to remove the melanoma and a small margin of normal skin around it.
