Question

In carcinoma of breast, spread of tumour through blood stream is to
(A) Thoracic vertebrae
(B) Ribs
(C) Lumbar vertebrae
(D) Femur
(E) Skull
Choose the correct order of frequency from the options given below:

• A. (A), (C), (B), (E), (D)
• B. (C), (D), (A), (B), (E)
• C. (B), (C), (A), (E), (D)
• D. (E), (C), (B), (A), (D)

Hint:

When considering the spread of carcinoma of the breast, the vertebral column (lumbar and thoracic regions) is more commonly affected due to the rich vascularization and blood flow from the breast.

Answer 1

The Correct Option is B

In carcinoma of breast, the tumour spreads through the blood stream most frequently to the lumbar vertebrae (C), followed by the femur (D). The thoracic vertebrae (A) are the next common site for metastasis, followed by the ribs (B), and finally the skull (E). Thus, the correct order of frequency is: (C), (D), (A), (B), (E).
