When the lymphatic structures are blocked due to tumors, the result is
a. increased pressure in the lymphatics proximal to the blockage
b. shrinkage of tissues distal to the blockage due to inadequate delivery of lymph
c. severe localized edema distal to the blockage
d. abnormally high lymph drainage from the distal region

The correct answer is option C. severe localized edema distal to the blockage.

Explanation:

The localized edema is a disorder that is taking place by swelling due to tumors or any other blockage that accumulate excessive fluid at specif sites such as lymphatic structures. It generally goes away on its own however it can be severe if occurs due to underlying diseases such as lymphedema due to tumors.

Thus, the correct answer is option C. severe localized edema distal to the blockage.

the correct answer is c
