Symptoms and screening

Possible cancer symptoms: when to seek medical advice

Many symptoms associated with cancer are more often caused by other conditions. A symptom list cannot tell you whether you have cancer, and some cancers cause no early symptoms. New, persistent or unexplained changes deserve medical assessment rather than guessing from a checklist.

Discuss your questions

Changes worth discussing

Pay attention to a change from what is normal for you. Examples include:

  • A new lump, swelling or breast change
  • Unexplained bleeding, blood in urine or stool, or unusual bruising
  • A cough or hoarse voice that persists, or difficulty swallowing
  • Unexplained weight loss, lasting fatigue, fever or night sweats
  • A lasting change in bowel habits
  • A changing mole or a sore that does not heal

When should I arrange an assessment?

Contact a doctor about unexplained changes, particularly if they persist, recur or worsen. Do not wait for pain: cancer can be painless. A new lump or unexplained bleeding should be discussed promptly. The urgency depends on the symptom and your condition; there is no single waiting period that suits everyone.

Assessment is different from screening

Screening is intended for people without symptoms. A new symptom needs its own assessment, even after a recent normal screening result. Your doctor reviews your history and examines you, then chooses relevant tests. Blood tests, scans or a biopsy may be needed; no single blood test can rule out every cancer.

Make the visit useful

Note when the change started, whether it is worsening and how it affects daily life. Bring existing reports and your medication list. Explain any personal or family cancer history. Before leaving, agree how you will receive results and what to do if symptoms continue or new ones appear.

Questions to ask at your consultation

  • What are the possible explanations for this symptom?
  • Which tests are useful in my situation, and why?
  • What changes should prompt an earlier review or urgent care?

Discuss your questions

A consultation can help put persistent or unexplained changes and existing reports into context and clarify the next assessment steps. Seek urgent care for the severe symptoms described above.
