Come si presenta un melanoma sulla pelle?

What are the chances of recurrence of melanoma in situ?
- Further primary i.e. not secondary developments, melanomas in situ have a recurrence rate of 0.5% per annum for the first five years post-treatment, decreasing thereafter. Certain age ranges demonstrate a greater propensity for recurrence too, those aged between 15 and 39 and 65 to 79 with the middle years less favoured.
What does malignant melanoma in situ mean?
- Melanoma in situ is also called stage 0 melanoma. It means there are cancer cells in the top layer of skin (the epidermis). The melanoma cells are all contained in the area in which they started to develop and have not grown into deeper layers of the skin. Some doctors call in situ cancers pre cancer.
Is melanoma the deadliest form of cancer?
- Malignant melanoma is a highly aggressive cancer that tends to spread to other parts of the body. These cancers may be fatal if not treated early. Like many cancers, skin cancers start as precancerous lesions. These precancerous lesions are changes in skin that are not cancer, but could become cancer over time.
Why is melanoma so deadly?
- Melanoma is an aggressive and deadly form of skin cancer. The relatively low toll of non-melanoma skin cancers may explain why people ignore or do not detect the more deadly melanoma. In so doing, they miss early detection of a cancer that can quickly turn deadly. Melanoma skin cancers kill nearly 8,000 people a year.
