1. Abnormal bowel movements – Warning sign of colon cancer
Many people think cancer must always cause pain, but that is not necessarily true. In colon cancer, the most important sign is often a change in bowel habits.
Symptoms such as changes in stool shape, hard stools, bleeding, prolonged diarrhea, or constipation may be warning signs. If you experience these, the best approach is to undergo a colonoscopy.
2. Persistent cough – Sign of lung cancer
A continuous cough that does not improve with medication, especially in smokers, should be evaluated with a lung CT scan.
Early-stage lung cancer often does not cause coughing up blood or obvious shortness of breath but may present as a persistent dry cough. Unfortunately, this symptom is easily mistaken for a sore throat or bronchitis, leading many people to delay medical evaluation and miss early detection.
If you have a long history of smoking, you should proactively get a chest CT scan for early screening.
