Explanation by: Admin

Cancer is a disease characterized by uncontrolled cell division, specifically due to uncontrolled mitosis, where cells keep dividing without the normal regulatory checks.

Why other options are incorrect:

  • (A) Loss of immunity of cells – While a weak immune system can fail to detect cancer, it’s not the direct cause.
  • (B) Uncontrolled meiosis – Meiosis is the division process for gametes (sperm/egg), not somatic cells where cancer occurs.
  • (D) Rupturing of cells – This can happen due to damage but doesn’t cause cancer.
