The Royal Marsden is a specialist cancer hospital in London providing diagnosis, treatment and research across a wide range of cancers. Its specialist environment brings together medical oncology, clinical oncology, surgery, radiotherapy, haematology, pathology, radiology and supportive care.

Cancer treatment at The Royal Marsden can involve multidisciplinary teams that assess each patient's diagnosis, cancer stage, pathology and previous treatment before developing an appropriate care plan. Depending on the disease, treatment may include surgery, chemotherapy, radiotherapy, targeted treatment, immunotherapy, hormonal treatment or combinations of these approaches.

Medical oncology focuses on systemic treatments that circulate through the body. These can include chemotherapy, immunotherapy, targeted therapies and hormone-based treatments where clinically appropriate.

Clinical oncology combines expertise in systemic cancer treatment and radiotherapy. Radiotherapy uses carefully planned radiation to treat malignant cells while attempting to protect surrounding healthy tissue.

Surgical oncology provides operations for selected cancers. Surgical treatment may be used to remove a primary tumour, obtain tissue for diagnosis, control local disease or manage complications. The type of surgery depends on tumour location, size, stage and relationship with nearby structures.

The hospital provides specialist services across numerous cancer types, including breast, prostate, lung, colorectal, gynaecological and other cancers. Haematology services cover blood cancers and related disorders.

The Royal Marsden also has an important research role. Specialist cancer centres conduct clinical research and participate in the development and evaluation of new treatments. Patients considering participation in research or clinical trials must meet specific eligibility requirements.

Diagnostic services are an important part of cancer management. Imaging, pathology and laboratory investigations help clinicians establish a diagnosis, determine disease extent and monitor response to treatment.

International patients considering cancer treatment in London should prepare pathology slides or reports, CT or MRI scans, PET imaging when available, laboratory results, operative reports and previous treatment summaries.

The hospital's multidisciplinary approach means patients may receive input from several specialists depending on their diagnosis. Treatment planning should always be individualized and based on the patient's medical circumstances.

For medical-tourism purposes, patients should verify current international-patient services, consultant availability, treatment costs, estimated treatment duration and follow-up arrangements directly with The Royal Marsden.
