What may increase the risk of physical activity for cancer patients?

• A. Hypertension
• B. Hyperglycemia
• C. Dehydration
• D. Marked anaemia

Answer: (D)

Marked anaemia reduces the blood’s ability to carry oxygen. When a person exercises, muscles demand more oxygen. If hemoglobin is low, the body can’t deliver enough oxygen to working muscles, leading to quicker fatigue, shortness of breath, rapid heart rate, dizziness, or fainting. In cancer patients, anemia is common due to disease and treatment, so this limitation directly raises the risk during physical activity. While dehydration, high blood pressure, or high blood sugar can create complications during activity, they don’t compromise oxygen delivery to the same extent as marked anaemia in this population, making anaemia the most impactful factor here.
