Study Notes
Global Cancer Impact
- Cancer is a leading health challenge worldwide, causing nearly 10 million deaths annually.
- In 2024, an estimated 19.3 million new cancer cases are projected alongside 10 million cancer deaths.
- Common cancers include breast, lung, colorectal, prostate, skin (non-melanoma), and stomach cancer.
- The annual economic cost of cancer exceeds $1.5 trillion USD, considering healthcare costs and lost productivity.
- Cancer significantly affects quality of life for patients and families, leading to emotional and physical distress.
Diet as a Modifiable Risk Factor
- Nutrient-rich diets with fruits, vegetables, and whole grains protect against oxidative damage and inflammation.
- Obesity is a significant risk factor for several cancers; weight management is essential.
- Minimizing processed meats can reduce exposure to carcinogens.
- Foods rich in omega-3s and phytochemicals can lower cancer risk through anti-inflammatory effects.
- Balanced diets promote hormonal balance, reducing the risk of hormone-related cancers.
Nutritional Management in Oncology
- Proper nutrition is crucial for treatment tolerance, enhancing recovery from chemotherapy, radiation, and surgery.
- Good nutrition maintains muscle mass and energy levels, improving treatment outcomes.
- Nutritional support helps manage side effects such as nausea, diarrhea, and appetite loss.
- Adequate nutrition strengthens the immune system, supporting overall recovery and quality of life.
Nutritional Challenges for Oncology Patients
- Anorexia and cachexia lead to significant weight loss and malnutrition among cancer patients.
- Treatments can alter taste perception, making food less appealing.
- Gastrointestinal issues (nausea, vomiting, diarrhea) commonly interfere with nutrient intake.
- Difficulty swallowing, psychological factors, and stress can impact eating habits.
Nutritional Screening and Assessment
- Regular assessments identify patients at risk of malnutrition, enabling timely interventions.
- Individualized nutrition plans should be tailored based on cancer type, treatment regimen, and health status.
- Important components of nutritional assessment include anthropometric measurements, biochemical data, and functional assessment.
Nutritional Strategies for Cancer Prevention
- Antioxidants protect against oxidative damage and may lower cancer risk.
- High-fiber diets promote digestion and may reduce colorectal cancer risk.
- Recommendations include consuming diverse fruits and vegetables, whole grains, and limiting red processed meats and alcohol.
Specific Nutritional Considerations
- For breast cancer, higher body fat levels correlate with increased risk; omega-3s may have protective effects.
- Lung cancer risk factors include smoking, but diets rich in antioxidants such as fruits and vegetables can mitigate risk.
Nutritional Management of Cachexia and Anorexia
- Cachexia is characterized by severe weight and muscle loss and requires high-calorie, high-protein diets to manage.
- Nutritional supplements and appetite stimulants may be necessary to counteract food intake challenges.
- Managing gastrointestinal toxicities involves small meals, hydration, and symptom management.
Dietary Considerations During Treatment
- Pre-surgery nutrition should focus on balanced diets with sufficient hydration and protein to support healing.
- Post-surgery, high-protein diets are vital for recovery, coupled with gradual reintroduction of solid foods.
- Chemotherapy necessitates high-protein and high-calorie diets to combat weight loss and muscle wasting, alongside hydration and small meals.### Cancer Treatment Nutritional Management
- Tailor diet to manage specific side effects associated with chemotherapy, immunotherapy, radiotherapy, and bone marrow transplant.
