Unintentional weight loss is associated with an increase in the risk of a cancer diagnosis within the coming year, according to a new study. Compared with participants who did not lose weight, recent weight loss was associated with significantly increased risk for several types of cancer, including upper gastrointestinal tract (including esophageal, stomach, liver, biliary tract, and pancreatic cancer), hematological (including non-Hodgkin lymphoma, multiple myeloma, and leukemia), colorectal, and lung cancers. However, recent weight loss wasn’t found to be associated with increased risk for other cancer types, such as breast cancer, genitourinary cancer, brain cancer, or melanoma.
