Understand that insensitivity to growth inhibition is an important cancer hallmark.. 2. List the tumor suppressor genes that if mutated result in this insensitivity.. II.Rate of growth. Most . benign tumors grow slowly . & most of cancers grow faster . & eventually spread locally & to distant sites (metastasis) & causing death.. In some exception, some benign tumors grow more rapidly than some cancers e.g. leiomyoma (uterine fibroid), which is benign smooth muscle tumor influence by estrogen & so increase in size during pregnancy.. infection in colorectal carcinogenesis.
