The type of water—whether it is tap, filtered, or bottled—is generally a personal choice. However, cancer patients should be cautious about the water they consume to avoid any additional health risks. Tap water should be clean and free from contaminants. Filtered water can remove impurities, making it a safer option. Bottled water should be from a reliable source to ensure it is free from harmful substances. Some studies suggest that alkaline water might offer additional benefits, but more research is needed to confirm these claims.
