Treatment for cancer
These are cancer treatments using medical technologies (interventional treatments).
Radiofrequency ablation (RFA) uses heat made by radio waves to kill cancer cells. You might have it on its own or with other treatments.
A laser is a very thin, focused beam of light. It heats the tissue to high temperatures, destroying abnormal cells. Lasers can focus very accurately on tiny areas.
High intensity focused ultrasound (HIFU) is a treatment that aims to kill cancer cells with high frequency sound waves. It is only available in specific centres or as part of a clinical trial.
Photodynamic therapy is a treatment for several different types of cancer. It uses a light sensitising drug and very bright light to destroy cancer cells.
Cryotherapy is a treatment that uses extreme cold to destroy cancer cells. It's a treatment for some early cancers and some pre cancerous conditions.
You might have ultraviolet (UV) light phototherapy treatment for a type of skin cancer called cutaneous T cell lymphoma (CTCL) and some other conditions. Find out more.
