Morphology
tumor + suppressor + gene
The meaning is directly compositional: 'tumor' (abnormal cell mass) + 'suppressor' (one that prevents or reduces) + 'gene' (DNA segment) yields 'a gene that prevents or reduces tumor formation.' This compound follows regular scientific noun-modifier patterns and has close equivalents in many languages, so a learner who knows the constituent words can infer the MWE meaning.
Etymology
Tumor suppressor gene gives a clear picture: a gene is like instructions, a suppressor is like a brake or guard, and a tumor is a growing lump. So a tumor suppressor gene is a gene that 'stops' or slows cells from making a tumor, which is why the phrase means a gene that keeps cell growth under control.
