It's important to be aware of any unexplained changes (signs and symptoms) to your body, this can be critical indicators that you might be having cancer. These signs and symptoms that you have cancer include; the sudden appearance of a lump, blood in your urine, or a change to your usual bowel habits.
These symptoms are often caused by other, non-cancerous illnesses, but it's important to see your GP so they can investigate.
If your GP suspects cancer, they'll refer you to a specialist – usually within two weeks.
The specialist will carry out further tests, such as a biopsy or X-ray, and plan any necessary treatment.
Other potential signs and symptoms of cancer are outlined below.
Lump in your breast
See your GP if you notice a lump in your breast or if you have a lump that's rapidly increasing in size elsewhere on your body.
Your GP will refer you to a specialist for tests if they think you may have cancer.
Coughing, chest pain and breathlessness
Visit your GP if you've had a cough for more than three weeks.
Symptoms such as shortness of breath or chest pain may be a sign of a severe (acute) condition, such as pneumonia. See your GP straight away if you experience these types of symptoms.
