Morphology

cancerous = cancer (semi-transparent) = cancer + ous

Formally derived from 'cancer' + '-ous', but this sense is a metaphorical extension (spreading/destructive), so the relation is not fully literal for learners.

Etymology

Cancerous comes from the same root as cancer and the star sign Cancer, which is a 'crab'. Because a crab seems to reach outward, cancerous is used for things that spread and cause harm, like corruption or bad feelings that eat away at something.
