6 signs of cancer, go see a doctor immediately

Coughing can occur with colds, flu, allergies, etc., and can also be a side effect of certain medications. However, a long-term cough (referring to a cough lasting more than three or four weeks) should not be ignored, especially for smokers, who should seek medical attention. It could be a symptom of lung cancer, chronic bronchitis, or acid reflux.

Difficulty swallowing

Some people experience difficulty swallowing, but do not take it seriously, thinking that eating more liquids and drinking more soup will solve the problem. In fact, dysphagia may be caused by digestive tract tumors, such as esophageal cancer, so you should ask a doctor to check.

We all know that when a pigmented mole on the skin grows larger, we should be alert to cancer. But other changes in the skin should also be noted.

If you smoke, pay special attention to white spots in your mouth or on your tongue; these changes indicate hematospermia. This is a precancerous lesion that may progress to oral cancer. Consult a doctor or dentist.

Many people, especially the elderly, believe that noticeable indigestion is the result of a heart attack. However, persistent indigestion may be caused by esophageal cancer or gastric cancer, so you should seek medical attention.
