These are numbers going from 0 through Roman numerals I to IV. The cancer is very small less than 1 mm deep and does not appear ulcerated.
It is localized but invasive meaning that it has penetrated beneath the top layer into the next layer of skin.
Melanoma first stage. Stage 0 is also called melanoma in situ. A normal mole is usually smaller than a pencil eraser has smooth and symmetrical borders an even color and stays about the. New or changing moles.
Survival rates decrease with later stages of melanoma. Melanoma is treated by cutting it out primarily. If you have melanoma skin cancer you doctor will say its in one of five stages as a way to describe how far along it is.
Stage I melanoma is typically treated by wide excision surgery to remove the melanoma as well as a margin of normal skin around it. First symptoms of melanoma. Treating stage I melanoma.
Stage I melanoma is no more than 10 millimeter thick about the size of a sharpened pencil point with or without an ulceration broken skin. Wide surgical tumor removal is typically used for these cancers and its often effective. In situ is a Latin phrase that means in position and this diagnosis means that the cancer cells.
However melanoma may also appear as a new mole. People should tell their doctor if they notice any changes on the skin. The first stage is called stage 0 or melanoma in situ.
The cancer is smaller than 1 mm in Breslow depth and may or may not be ulcerated. Melanoma is staged as follows. A higher number such as stage IV means cancer has spread more.
The first group includes cancers that have not spread beyond the area bordering the skin irregularity. Melanoma usually appears on the skin as a new spot or growth or a change in an existing mole. You have abnormal melanocytes but only on the outermost layer of skin epidermis.
More serious interventions may be needed to treat the cells. Melanoma can also start in the eye the intestines or other areas of the body with pigmented tissues. In stage 0 abnormal melanocytes are found in the epidermis the very top of the skin and have not spread to the dermis the second layer of skin below the epidermis.
Stage 0 and I are localized meaning they have not spread. In the first or second stage this may be enough to lose stop the progress in its tracks. The last stage is called stage 4.
Radiation and chemotherapy drug are two such methods. As a rule the lower the number the less the cancer has spread. It is also not dividing rapidly.
Surgery to remove the melanoma and a border of normal skin completes treatment. This noninvasive stage is also called melanoma in situ. The earliest stage melanomas are stage 0 melanoma in situ and then range from stages I 1 through IV 4.
Melanoma is localized in the outermost layer of skin and has not advanced deeper. The tumor and a large area of surrounding normal skin are outlined by an elliptical border and then removed. Often the first sign of melanoma is a change in the shape color size or feel of an existing mole.
This is also called melanoma in situ. The earliest stage of melanoma is stage 0 also known as melanoma in situ or carcinoma in situ. Some stages are split further using capital letters A B etc.
It has not spread to lymph nodes or distant sites. Most often no other treatment is needed. There is no evidence that Stage I melanoma has spread to the lymph tissues lymph nodes or body organs.
The staging system is detailed in the AJCC Cancer Staging Manual released by the American Joint Committee on Cancer. The width of the margin depends on the thickness and location of the melanoma. Stage I melanoma means the cancer cells have grown deeper into the skin but have not spread to the lymph nodes or other parts of the body.
