Understanding the signs and symptoms of cancer, why they matter, and when to seek medical advice, can help lead to earlier diagnosis and better outcomes. Noticing changes in your body can feel worrying – but many symptoms aren’t cancer.
Signs are physical changes (like lumps or bleeding), while symptoms are feelings you experience (like pain or fatigue). These can vary and whilst they may not be cancer it’s always best to check with a doctor if you’re concerned or notice any changes in your body.
Early detection saves lives, so it’s important to know what to look for. You can also explore the signs and symptoms of specific cancers by cancer type.
