The relationship between high protein diets and cancer progression is complex and not yet fully understood. Some studies suggest that certain types of protein, particularly those from animal sources, may be linked to an increased risk of certain cancers. However, other research indicates that protein is vital for maintaining muscle mass and overall health during cancer treatment. Plant-based proteins, which are often lower in saturated fat and contain beneficial phytochemicals, may be a better option for some patients. It is important for cancer patients to discuss their dietary choices with their healthcare team to tailor recommendations to their specific needs and circumstances.
