Lumps in the breast can be benign (non-cancerous) or malignant (cancerous).
Unfortunately, if left untreated, the primary tumour can spread via the lymph nodes or blood vessels to other parts of the body including the liver, lungs and bones. The spread of cancer can create more tumours around the body, which is called metastasis.
Breast cancer affects both women and men, but is the most common cancer affecting Australian women. In 2021, breast cancer was the most commonly diagnosed cancer in Australia.
