To support a patient with breast cancer in managing treatment-related side effects, ensure they have a named clinical nurse specialist or key worker to provide continuous support throughout diagnosis, treatment, and follow-up. This facilitates personalised care and continuity.

Provide clear, written information about common side effects such as cancer-related fatigue, including its management and available psychosocial support and patient-led groups.

Offer timely access to exercise programmes to help manage cancer-related fatigue.

Inform patients about the risk of lymphoedema before treatment starts, including risk reduction strategies such as maintaining a healthy weight, infection prevention, skincare advice, physical activity, and how to self-monitor for early signs and symptoms. Provide information in a suitable format for patients to take away.

For patients with advanced breast cancer experiencing significant fatigue, assess for treatable causes and offer appropriate management.

Discuss menopausal symptoms and avoid recommending unproven treatments such as soy, red clover, black cohosh, vitamin E, or magnetic devices.

Offer baseline bone mineral density assessment (DEXA scan) for women starting aromatase inhibitors, with treatment-induced menopause, or starting ovarian ablation/suppression, to manage bone health proactively.

Ensure patients have an agreed, written care plan recorded by a named healthcare professional, including details of surveillance, signs and symptoms to watch for, and contact details for specialist and support services.

Encourage a healthy lifestyle to reduce recurrence risk, including maintaining a healthy weight, limiting alcohol intake to below 5 units per week, and regular physical activity.
