This is because some treatments reduce the level of oestrogen, which helps keep bones strong. For example, chemotherapy can cause an early menopause, which reduces oestrogen. Some hormonal therapies cause a temporary or permanent menopause. Joint stiffness and pain are common side effects of aromatase inhibitor drugs (AIs). They reduce the risk of breast cancer coming back so it’s very important to keep taking them. Your doctor can prescribe drugs to control joint pain or change you to a different AI if you have difficult side effects. You will have a scan to check your bones before and sometimes during treatment with an AI.
