Abstract
<jats:p>Haematological cancers or blood cancers are types of cancer that affect blood cells. Studies have shown that patients with haematological cancers are at high risk of malnutrition due to treatment side effects. The nutritional risk for adults with haematological cancer is associated with diagnosis, treatment and side effects of treatment. When calculating nutritional requirements for adults with haematological cancers, there may be local. Nutritional interventions should be initiated where there is a risk of malnutrition. Side effects of treatment can act as barriers to dietetic interventions. Frequent monitoring of nutritional status is required and should include assessment of oral intake, tolerance of enteral and parenteral nutrition, along with anthropometrics, biochemistry and toxicity symptoms. Evaluating the nutritional status of adults and providing nutritional advice and interventions during different stages of treatment is a vital part of holistic and supportive care.</jats:p>
