These are the medical treatments doctors use to treat people with cancer. Surgery, radiotherapy, chemotherapy, hormonal and targeted therapies are all conventional medical treatments.
Many cancers are cured with these treatments. Even when treatments are unable to cure cancer, they often help people live for longer and/or reduce their symptoms.
Conventional medical treatments for cancer are scientifically tested and researched. This means we know how safe and effective they are and what their possible side effects are. This is called evidence-based medicine.
