What causes prostate cancer?

1-minute read

Prostate cancer occurs when the cells in the prostate gland grow in an abnormal way, creating a lump of tissue, known as a 'tumour'.

While the causes of prostate cancer are not fully understood, there are a number of factors associated with the risk of developing the disease.

These factors include:

  • increasing age
  • family history — having a father or brother who had prostate cancer increases the risk
  • changes to your genes — changes in the BRCA1 or BRCA2 genes may increase the risk of developing prostate cancer in some men
  • eating a high fat diet and not enough fresh fruit and vegetables
  • having high testosterone levels
