Cancer often develops silently. In many cases, the earliest changes in the body are easy to dismiss as stress, age, or a minor infection. However, certain early cancer symptoms act as important warning signs that something more serious may be going on. Recognising these patterns and acting quickly can lead to earlier diagnosis, simpler treatment, and better outcomes.
While not every symptom means cancer, some changes should never be ignored—especially when they persist or have no clear cause. Understanding key signs of cancer helps you decide when to contact a doctor and when to ask specifically for an oncology opinion.
