It is important to be aware of any unexplained changes to your body, such as the sudden appearance of a lump, blood in your urine or a change in your usual bowel habits.
These symptoms are often caused by other, non-cancerous illnesses, but it is important you see your GP so they can investigate. 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 is 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
You should visit your GP if you have had a cough for more than three weeks.
Symptoms such as shortness of breath or chest pain may be a sign of an acute (severe) condition, such as pneumonia (a lung infection). Go to see your GP straight away if you experience these types of symptoms.
Changes in bowel habits
Go to see your GP if you have experienced one of the changes listed below and it has lasted for more than a few weeks:
You should also go to see your GP if you have any unexplained bleeding such as:
- blood in your urine
- bleeding between periods
- blood from your back passage
- blood when you cough
- blood in your vomit
Go to see your GP if you have a mole that:
- has an irregular or asymmetrical shape
- has an irregular border with jagged edges
- has more than one colour (it may be flecked with brown, black, red, pink or white)
- is bigger then 7mm in diameter
- is itchy, crusting or bleeding
Any of the above changes means that there is a chance you have malignant melanoma (skin cancer).
Unexplained weight loss
You should also go to see your GP if you have lost a lot of weight over the last couple of months that cannot be explained by changes to your diet, exercise or stress.
