Cancer symptoms

It can be easy to assume that new problems are part of the ageing process or existing conditions. But if you are experiencing any new, persistent symptoms, there is a chance they could be a sign of cancer, so it’s important that you tell a GP or another healthcare professional.

In particular, if you notice any of the following symptoms, you should contact your GP:

• Hoarseness of the voice that lasts more than three weeks.
• A cough that lasts more than three weeks, or coughing up blood.
• A new lump that doesn’t go away.
• A sore or ulcer, on the skin or in the mouth, which won’t heal.
• A mole that changes in size, shape, sensation or colour, or any change to the skin.
• Blood in your stools or urine.
• Bleeding from the vagina.
• Indigestion that doesn’t go away or keeps coming back.
• Unexplained weight loss.
• A change in bowel habit that lasts longer than six weeks.

These symptoms can be caused by conditions other than cancer. Even if they are not symptoms of cancer, your GP will be able to help you manage them.

Some people with these symptoms are reluctant or embarrassed to tell their GP. However, if cancer is found early, treatment is more likely to be successful, so it's important to tell your GP about these symptoms.
