2. Drastic and unexplained weight loss
If you are experiencing weight loss quickly and don’t really have an explanation for it, there could be a deeper reason.
Most cancers will cause you to lose weight at some point so keep an eye on those numbers.
3. Persistent pain
Constant pain that seemingly has no cause or reason can be a sign of cancer, especially if you are taking treatment but it is not working.
Depending on where the pain is in your body means it might be a symptom of a brain tumor, rectum, ovary or colon cancer.
