Key points

  • Breast cancer is the second most common cancer in women, after skin cancer.
  • Warning signs include lumps, changes in breast shape or nipple, unusual pain, and skin changes.
  • The disease is classified as non-invasive (contained within the breast) or invasive (spread to surrounding tissue).
  • Mammograms can detect breast cancer early, possibly before it has spread.

Medicines listed for Breast Cancer

The five products on this page contain four active ingredients, all supplied as tablets. Tamoxifen and raloxifene belong to a class called selective oestrogen receptor modulators, which work by blocking oestrogen’s effect on breast tissue. Anastrozole and exemestane are aromatase inhibitors, a group that lowers the amount of oestrogen the body produces. Both classes target oestrogen, a hormone that can fuel certain breast cancers.
