Final answer:
A qualified healthcare professional is essential for newly diagnosed cancer patients to manage nutrition, address symptoms, and counteract taste changes, which can significantly influence the treatment outcome.
Step-by-step explanation:
It is recommended to have a person who is newly diagnosed with cancer see a qualified healthcare professional to prevent and resolve nutrient deficiencies, address symptoms such as anorexia and early satiety, and address changes in taste and smell, as well as the disruption of eating habits. These professionals, like registered dietitians, are adept at designing nutrition plans that cater to the specific needs of cancer patients. They help manage the nutritional challenges that arise due to the cancer itself or the side effects of cancer treatment. These efforts are crucial because proper nutrition can play a significant role in the overall outcome of cancer treatment.
