NCI: Stage II is divided into stages IIA, IIB, and IIC. In stage IIA, (1) the tumor is more than 1 but not more than 2 millimeters thick, with ulceration (a break in the skin); or (2) more than 2 but not more than 4 millimeters thick, with no ulceration. In stage IIB, (1) the tumor is either more than 2 but not more than 4 millimeters thick, with ulceration; or (2) more than 4 millimeters thick, with no ulceration. In stage IIC, the tumor is more than 4 millimeters thick, with ulceration.,NCI: Stage II includes: IIA: (T2b, N0, M0); (T3a, N0, M0); IIB: (T3b, N0, M0); (T4a, N0, M0); IIC: (T4b, N0, M0). T2b: Cutaneous melanoma with a tumor measuring 1.01-2.0 mm in thickness, with ulceration. T3a: Cutaneous melanoma with a tumor measuring 2.01-4.0 mm in thickness, without ulceration. T3b: Cutaneous melanoma with a tumor measuring 2.01-4.0 mm in thickness, with ulceration. T4a: Cutaneous melanoma with a tumor measuring more than 4.0 mm in thickness, without ulceration. T4b: Cutaneous melanoma with a tumor measurin
