What is Breslow Depth melanoma?
Breslow thickness is the measurement of the depth of the melanoma from the surface of your skin down through to the deepest point of the tumour. It’s measured in millimetres (mm) with a small ruler, called a micrometer.
What is TNM staging melanoma?
The TNM staging system is how the doctor stages your melanoma skin cancer. The stage of a cancer tells your doctor how thick it is and how far it’s spread. It helps your doctor decide which treatment you need. TNM staging for melanoma skin cancer is complicated.
How is Breslow thickness measured?
1 Breslow thickness is measured from the top of the granular layer of the epidermis (or, if the surface is ulcerated, from the base of the ulcer) to the deepest invasive cell across the broad base of the tumour (dermal/subcutaneous) as described by Breslow.
Is Breslow Depth or Clark’s level more important?
Tumor thickness as defined by the Breslow Depth of Invasion is the most important determinant of prognosis for melanomas.
What is the difference between Breslow and Clark?
The Clark scale is used to determine how many layers of the skin the melanoma has grown into; the Breslow scale is used to determine how thick the melanoma is. The melanoma cells are only in the top layer of the skin, the epidermis.
Why is Breslow thickness important?
The Breslow Depth is a helpful measure of how far melanoma has invaded the body. Knowing the depth of melanoma is helpful because it is important when considering future treatment. The Breslow Depth has been replaced by the American Joint Committee on Cancer (AJCC) staging system.
Is Stage 0 melanoma precancerous?
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.
