What should you know about de novo breast cancer?

It is also called de novo metastatic breast cancer. This differs from breast cancer that returns in distant organs after treatment for an earlier, localised diagnosis.

Metastatic disease develops when breast cancer cells travel to distant parts of the body. Commonly assessed sites include bone, liver, lungs, and brain. Cancer found at those sites is still breast cancer because it retains characteristics of the breast tumour.

A biopsy confirms the cancer type and tests features such as hormone receptors and HER2. Imaging maps where disease is present. In selected situations, profiling of tumour tissue can identify changes that influence treatment. A sample from a metastatic site may be recommended because its biology can differ from the breast lesion.

Treatment usually centres on medicines that circulate through the body. The choice may include hormone therapy, targeted therapy, chemotherapy, or immunotherapy, depending on tumour markers, previous health conditions, symptoms, and where the cancer is active. Radiotherapy or a procedure may help control a specific painful or threatening site.

Before the planning visit, gather imaging reports, biopsy results, current medicines, and details of other illnesses. Tell the team about pain, appetite, sleep, mobility, breathlessness, and emotional strain. Supportive and palliative care can be provided alongside cancer treatment to improve symptom control and daily function.

Contact the oncology team urgently for new weakness or numbness, trouble walking, loss of bladder or bowel control, severe or rapidly worsening back pain, a new seizure, confusion, or a severe new headache. These symptoms can signal pressure on the spinal cord or involvement of the brain and need rapid assessment.

Seek immediate care for significant breathing difficulty, chest pain, coughing blood, uncontrolled bleeding, or a sudden marked decline. Fever during treatment also needs prompt advice because some cancer medicines reduce the body's ability to fight infection. Use the emergency instructions and contact numbers supplied by your treatment centre.

Where has the cancer been found? Which biopsy confirmed the diagnosis? What are the hormone-receptor and HER2 results? Is another biopsy or tumour profiling useful? What is the goal of the proposed treatment, how will response be checked, and whom should I contact after hours for new symptoms?
