Cancer symptoms

Cancer symptoms vary depending on many factors, such as the cancer type, stage, size and location. The early stages of cancer may not produce noticeable symptoms. As the disease progresses, symptoms often become more apparent.

Some general symptoms of cancer include:

  • Fatigue
  • Unexplained weight loss/gain
  • Fever
  • Pain
  • Change in appetite
  • Nausea, vomiting
  • Skin changes

Many symptoms share characteristics of other, non-cancerous conditions. If you experience any persistent symptoms or other changes in your health, it’s important to see a doctor as soon as possible.

Diagnosing cancer

If you experience any cancer symptoms, it’s important to consult with a medical professional. A doctor will evaluate your symptoms and use diagnostic tests to first confirm the presence of disease, and then to identify the correct tumor type, location, extent and stage. An accurate cancer diagnosis helps your doctors determine a treatment approach that works for you.
