Problem 21
Why are there no skin cancers that originate from stratum corneum cells?
Problem 21
In what ways are adipose tissue and bone similar? How are they different?
- In adults, over 90% of all cancers arise in epithelium. Such cancers are called carcinomas, or adenomas (adenocarcinomas) if they arise in glandular epithelia. In fact, cancers of the skin, lung, colon, breast, and prostate are all in these categories. Why do you think this is so?
