What can cause abnormal cellular proliferation?

• A. Factors leading to cancer and other growth disorders.
• B. Conditions that promote normal tissue maintenance.
• C. Dehydration.
• D. Vitamin C deficiency.

Answer: (A)

Abnormal cellular proliferation happens when the regulatory systems that keep cell division in check fail, leading to unchecked growth as seen in cancer and other growth disorders. Factors that drive this include genetic mutations that activate growth-promoting pathways, deactivate tumor suppressors, or disrupt DNA repair, as well as chronic inflammation or exposure to carcinogens that constantly push cells to divide. In contrast, normal tissue maintenance relies on balanced turnover with controlled proliferation and timely cell death, so conditions like dehydration or vitamin C deficiency don’t inherently cause abnormal proliferation.
