Breast cancer is one of the most common types of cancers in the UK, according to the NHS.
Around one in every eight women are diagnosed with the deadly condition during their lifetime.
Women should check their breasts regularly to check for any changes to the tissue.
You should see a GP if you notice any differences to your breasts, the NHS urged.
These are five signs to look out for of breast cancer.
“The first symptom of breast cancer most women notice is a lump or an area of thickened tissue in their breast,” said the NHS.
“Most breast lumps [90 per cent] aren’t cancerous, but it’s always best to have them checked by your doctor.
“See your GP as soon as possible if you notice any symptoms of breast cancer, such as an unusual lump in your breast or any change in the appearance, feel or shape of your breasts.
“Your GP will examine you. If they think your symptoms need further assessment, they’ll refer you to a specialist breast cancer clinic.”
When checking your breasts, look out for any new lumps that weren’t there before.
A change in the size of shape of one, or both, of your breasts may also be an early warning sign of the cancer.
Other breast cancer symptoms can include a bloodstained discharge from either of your nipples, a lump or swelling in either of your armpits, or finding a change in the appearance of your nipples.
Breast pain isn’t usually a symptom of breast cancer, the NHS added.
Knowing what your breasts normally feel like will help you to become more aware of any abnormal changes.
Detecting breast cancer earlier means that treatments may be more effective.
It’s not known if breast cancer can be prevented, the NHS said.
But, maintaining a healthy weight and regular exercise may help to lower your risk.
There are also benefits for women who have a low intake of saturated fat and alcohol.
It’s also been claimed that women who breastfeed are less likely to develop breast cancer.
More than 50,000 women are diagnosed with invasive breast cancer every year in the UK.
