Final answer:
Hyperplasia without atypical cells is generally considered a benign condition with a low risk of progressing to carcinoma, while hyperplasia with atypical cells has a higher risk of progressing to carcinoma.
Step-by-step explanation:
Hyperplasia is a condition characterized by an increase in the number of cells in an organ or tissue. It can occur with or without the presence of atypical cells. Hyperplasia without atypical cells is generally considered a benign condition and does not have a high risk of progressing to carcinoma, which is a type of cancer. On the other hand, hyperplasia with atypical cells, also known as atypical hyperplasia, has a higher risk of progressing to carcinoma and requires further evaluation and monitoring.
