Cancer is a formidable disease, but early detection can significantly increase the chances of successful treatment. Unfortunately, many early warning signs are subtle and often dismissed. Here are some key symptoms to watch for:

**1. Changes in Stool**
Persistent diarrhea, irregular bowel movements, or changes in stool size may indicate digestive tract cancer. If these symptoms persist alongside abdominal discomfort, seek medical advice.

**2. Changes in Urination**
Frequent urination, discomfort, or difficulty controlling the flow could signal prostate or bladder cancer. Don’t ignore these symptoms, especially if they persist.

**3. Unexplained Weight Loss**
Sudden, unintentional weight loss can be an early warning sign of various cancers, including stomach, lung, or pancreatic cancer.

**4. Persistent Cough or Hoarseness**
A cough that lingers for weeks, especially if accompanied by blood, could indicate lung or throat cancer.

**5. Unusual Lumps or Swelling**
Any persistent lump or swelling, especially in the breast, armpit, or neck, should be checked by a doctor.

Recognizing these symptoms early can lead to timely intervention and better outcomes.
