Explanation:

1. removal, excision

In medical terminology, the suffix "-ectomy" means removal or excision (e.g., appendectomy is the removal of the appendix). Another option could be "-otomy" but that is more about incision, while "-ectomy" is specific to removal. So a common part for removal/excision is "-ectomy" (or the combining form "resect/o" but suffix is more direct here, and "-ectomy" is a standard suffix for excision).

The combining form for brain is "encephal/o" (e.g., encephalitis is inflammation of the brain) or "cerebr/o" (relating to the cerebrum, part of the brain). "Encephal/o" is a more general combining form for the brain.

The prefix "trans-" means across or through (e.g., transatlantic means across the Atlantic, transdermal means through the skin). Another option is "per-" (through) but "trans-" is a very common prefix for across/through.

Answer:

-ectomy (or e.g., resect/o, but -ectomy is a common suffix for this meaning)
