Improved methods of early detection and modern therapeutic protocols for malignant diseases led to better survival and increased ratio of cured patients diagnosed for malignances. Cancer survivors are population with increased risk not only for recurrence of the disease but for new primaries and other chronic conditions. Life-style factors, such as nutrition, physical activity and weight management, play key role in preventing these risk factors. Patients in each phase of malignant disease have specific nutritional needs and location of the primary disease and therapeutic modalities additionally modify these needs.
