Here’s a detailed breakdown of 16 early warning signs that cancer may be developing in your body, along with explanations and guidance on what to do if you notice them. These signs are subtle and can be mistaken for less serious conditions, which is why awareness is key.
1. Unexplained Weight Loss

Direction: Track your weight regularly. If you notice unexplained loss, consult a doctor for evaluation.
2. Persistent Fatigue

Direction: Note how long fatigue lasts. Persistent fatigue that doesn’t improve with rest should prompt a medical check-up.
3. Unusual Bleeding or Discharge
