1. Unexplained Weight Loss: Losing weight without even trying might seem like a good thing, but this could be an indication of cancer, such as pancreatic, lung, or stomach cancer.
2. Persistent Fatigue: Feeling extremely tired even when you have had enough rest might be a sign of cancer growth, significantly if your situation does not improve after taking ample rest. It frequently occurs in colon or leukemia cancers.
3. Fever: A fever that does not go away and cannot be explained by a known infection may indicate the presence of cancer, especially if accompanied by night sweats. It happens in leukemia or lymphoma.
4. Pain: Lasting pain, including headaches or back pain, can indicate numerous types of cancer in situations where other treatments fail to relieve them.
