If your tumour is hormone-receptor positive, it may depend on hormones to grow. Hormone therapy lowers hormone levels or blocks their effects, starving the cancer of what it needs.
Common hormone therapies
- Tamoxifen: blocks oestrogen at the cancer cell
- Aromatase inhibitors: lower oestrogen production after menopause
- Ovarian suppression: stops the ovaries producing oestrogen
Hormone therapy is usually a daily tablet taken for five to ten years. Side effects can include hot flashes, joint pain and fatigue — manageable with support, and the protection lasts.
