Nutrition plays a critical role in the management and recovery of cancer patients, as it directly impacts their strength, immunity, and treatment tolerance. Nurses serve as key healthcare providers in assessing nutritional status, educating patients and families about dietary needs, and collaborating with dietitians to create personalized nutrition plans. They also monitor for signs of malnutrition, manage side effects that interfere with eating (like nausea or mucositis), and encourage adequate fluid and nutrient intake. By promoting optimal nutrition, nurses help improve quality of life, enhance treatment outcomes, and support overall patient well-being during cancer care.
