A nurse is teaching a client about the seven warning signs of cancer. Which of the following signs should the nurse include as manifestations of cancer? (Select all that apply.)

A. A nonhealing sore is an early warning sign of cancer, particularly skin or oral cancers, and warrants prompt evaluation. B. Bloating is nonspecific and not included in the classic seven warning signs. While it can be associated with some cancers (e.g., ovarian), it is not considered a primary early indicator. C. Nagging cough can indicate lung or throat cancer and is considered an early warning sign. D. Change in moles may indicate melanoma and is included in the warning signs for early detection. E. Change in bowel pattern may indicate colorectal or gastrointestinal cancers and is a key early warning sign.
