Final answer:
Signs and symptoms of cancer can include abnormal fatigue, bleeding, lumps, persistent cough, and unexplained weight loss, among others. These require medical evaluation as early detection and treatment can greatly improve outcomes.
Step-by-step explanation:
Some of the signs and symptoms to watch for in cancer development include uncommon fatigue, unusual bleeding, and persistent changes such as unusual lumps or swelling, which may indicate the presence of a tumor. Other signs might include chronic pain, ulceration, enlarged lymph nodes, persistent cough, unexplained weight loss, poor appetite, excessive sweating at night, unexplained anemia, and other specific paraneoplastic phenomena. These symptoms are not necessarily diagnostic of cancer, as they can be attributable to a variety of health issues, but they warrant medical evaluation to determine the underlying cause. It is important to remember that detecting and treating cancer early can often lead to a cure, making an awareness of these warning signs crucial for timely medical consultation.
