6. Swollen Lymph Nodes

Lymph nodes are small, bean-shaped glands that often swell due to infections. However, persistent swelling without a clear cause could indicate leukemia or lymphoma.

7. Difficulty Swallowing

Occasional swallowing difficulty isn’t alarming, but persistent trouble, especially when accompanied by weight loss or vomiting, could be a symptom of esophageal or throat cancer.

8. Unexplained Weight Loss

Unexpected weight loss without changes in diet or exercise could indicate pancreatic, stomach, or lung cancer. If you lose more than 10 pounds without effort, see a doctor.

9. Chronic Heartburn

Frequent heartburn that doesn’t improve with lifestyle changes may indicate esophageal cancer. Persistent acid reflux should be evaluated by a doctor.

10. Mouth Changes

White or red patches inside the mouth or on the lips may be signs of oral cancer, particularly in individuals who smoke or drink excessively.
