Regular breast examinations are so important to keep track of any changes. Never done one before? Spend some time feeling your breast all-over to get an idea of what it normally feels like. Then check one week a month, such as the week after your period.
To start, stand in front of a mirror and look for any immediate changes, such as the shape, puckering or dimpling in the skin, changes to the nipple or any discharge.
Then, with one hand by your side, use the flats of your fingers to to gently massage and check all around your breasts, making sure to follow the tissue up to the underarm and under the boob. See the video above for a simple demonstration.
But it's about more than just feeling for lumps - here are the seven signs to look out for.
1.Dimples or puckering.
Dimples are a significant sign of breast cancer yet one that many women are unaware of. Thankfully, due to women like Lisa Royle and more recently Claire Warner sharing warnings to #CheckYourDimple, awareness is slowly increasing.
Notice either of these? Make an appointment at the doctors to get it checked out, just in case.
2. Nipple changes.
Behind the nipples is a common location for tumours, which can often change the way it looks and feels. If your nipple is inverted, flattened or indented (and it wasn't like that previously) get it checked.
Breast cancer can also reduce sensitivity of the nipples. (Post continues after gallery.)
Unless you're breastfeeding, any discharge from your nipples should be looked at by a doctor as it may be caused by a tumour near the milk duct. The skin of the nipple may also become crusty, scaly or inflamed.
According to Cancer Research UK, itchiness is a rare but important sign of inflammatory breast cancer. In this type of cancer, the area of skin over the tumour can become inflamed, red, painful and itchy. A condition associated with breast cancer called Paget's disease of the nipple, can also cause itchiness.
