Tenovus Cancer Care's first Mobile Support Unit was launched in February 2009. Since its launch, the Unit has opened its services in more than 50 locations and has accommodated over 5,000 patients and visitors. Working with Velindre NHS Trust, Tenovus Cancer Care has been delivering chemotherapy and other cancer treatments in Cwmbran and Nantgarw. During this period, over 10,000 treatments have been provided. In October 2013 the second Mobile Support Unit was launched to deliver support for people with Lymphoedema, an incurable condition which can be a side-effect of cancer treatment. In October 2018, HRH The Princess Royal unveiled the charity's new £1m Mobile Support Unit, the largest mobile chemotherapy treatment unit in the world. It is 60% bigger than the first Mobile Support Unit, with seven chemotherapy chairs and is capable of seeing 30 patients a day and delivering more than 8,500 treatments a year. Calculations show that the two existing Mobile Support Units save the NHS in Wales more than £1m a year, and the new Mobile Support Unit could deliver more than 125,000 treatments over the course its lifetime.
