What does dysplasia indicate about cell changes?

Dysplasia is a term specifically used to describe abnormal changes in cells that can involve variations in size, shape, and organization of cells within a tissue. It is often associated with pre-cancerous lesions where the cells exhibit atypical features compared to normal cells. This condition can indicate underlying issues with cellular health and may reflect an increased likelihood of developing cancer in the affected tissue if left unchecked.

The other options reflect different aspects of cellular health and growth. For example, normal growth and organization of cells signifies healthy and typical function, which does not align with the concept of dysplasia. Reversible cell type replacement pertains more to metaplasia, where one cell type changes to another in response to stress. Increased number of cells could relate to hyperplasia, which signifies a proliferation of cells without the abnormal organization seen in dysplasia. Thus, the specific characteristics of dysplasia as abnormal alterations in cellular morphology make the chosen answer the right one.
