We asked Dr Nicola Davis, specialist breast and general surgeon, whether a lump is the only sign of breast cancer.
Breast cancer is the most common cancer affecting New Zealand women with more than 3,300 diagnosed per year. Screening mammograms with BreastScreen Aotearoa can diagnose small, asymptomatic cancers early, resulting in better outcomes.
Being breast aware by performing regular self-examinations is also important to detect changes early.
A new lump is a common symptom of breast cancer. Breast cancer lumps are usually hard, non-painful and grow with time but they may just be a thickened area that feels different to the rest of your breast tissue. Checking under the armpits for lumps is also important.
You should also be on the lookout for other breast changes, for example, nipple changes – including inversion, discharge and crusting – may signify cancer. Distortion of the breast with an alteration of shape, dimples, dents or puckering can be caused by a tumour pulling the skin inwards. Changes to the skin, including persisting or progressive redness, dimpling/orange peel appearance or thickening may also indicate cancer. Finally, unusual pain that is not related to your menstrual cycle is an uncommon symptom.
Whilst most breast changes are due to non-cancerous conditions, it is important that you see your GP for an assessment if you notice something unusual in your breasts.
