Dysplasia may arise from chronic irritation or infection and may be precancerous.

• A. It is never cancer
• B. It is always malignant
• C. It is unrelated to cancer risk
• D. It may be precancerous arising from chronic irritation or infection

Answer: (D)

Dysplasia is an abnormal arrangement of cells that signals a precancerous state—the cells look atypical and their architecture is disrupted, but they have not invaded nearby tissues. Chronic irritation or infection can sustain inflammation and promote genetic changes that push tissues toward dysplasia. Because these abnormal cells carry a risk of progressing to cancer if the changes accumulate, dysplasia is considered precancerous. The statement that it may be precancerous arising from chronic irritation or infection captures this relationship between chronic stimuli, dysplastic change, and cancer risk. The other options mischaracterize the condition: it is not simply never cancer, it is not inherently malignant, and it is indeed related to cancer risk.
