Kingston Hospital wants to extend its oncology unit to bring cancer diagnosis and treatment services into one building.
The Sir William Rous Unit is proposed to be expanded to bring in chemotherapy from the Roehampton Wing, as well as providing space for examination rooms, drugs facilities and a roof terrace for relaxation.
It currently houses oncology outpatients services - cancer treatment for patients who do not have to stay in the hospital.
According to plans, the new unit will "mimic the chemotherapy service provided by the Royal Marsden".
The National Cancer Patient Experience Surveys, published in 2016, showed that the haematoma-oncology service scored above average in just five of 59 questions.
The hospital claims this development would be "an opportunity to improve patient experience".
