Answer:
The options
A. No evidence of primary tumor, no abnormal regional lymph nodes, and no evidence of distant metastasis
B. Carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis
C. Can t assess tumor or regional lymph nodes and no evidence of metastasis
D. Carcinoma in situ, no demonstrable metastasis of the regional lymph nodes, and ascending degrees of distant metastasis
The CORRECT ANSWER IS B.
B. Carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis
Explanation:
A. No evidence of primary tumor, no abnormal regional lymph nodes, and no evidence of distant metastasis❌
No proof of primary, no unusual regional lymph nodes, and no sign of distant metastasis is classified as T0, N0, M0.
B. Carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis✔
TIS, N0, M0 shows carcinoma in situ, no abnormal regional lymph nodes, and no evidence of distant metastasis.
C. Can t assess tumor or regional lymph nodes and no evidence of metastasis❌
If the tumor and regional lymph nodes can't be evaluated and no proof of metastasis exists, the lesion is grouped to be TX, NX, M0.
D. Carcinoma in situ, no demonstrable metastasis of the regional lymph nodes, and ascending degrees of distant metastasis❌
A Gradual rise in tumor size, no signs of metastasis of the regional lymph nodes, and increasing degrees of farther metastasis is classified as T1, T2, T3, or T4; N0; and M1, M2, or M3.
