So basically, I've got a bio midterm tomorrow, and so in the process of studying, I realized I totally don't get that! Even my bio friends are like, what….? So if ANYONE can help us out here, that would be fantastic! Thanks!
Answer:
The word tumor is defined (in Answers.com) as “An abnormal growth of tissue resulting from uncontrolled, progressive multiplication of cells and serving no physiological function; a neoplasm.” So your teacher is playing with semantics here.
The only way a “mass” could be non-cellular would be if it were cystic - - a contained area of fluid. We see this with some ovarian tumors which might be benign or malignant. The benign ones are ovarian serous cystadenomas or mucinous cystadenomas which can be quite massive tumor masses. These do contain cells however in the membranous sacs surrounding the fluid
