Coronavirus resources & support Coronavirus FAQ Does having had cancer treatment in the past (for example, stem cell transplants, chemotherapy, radiotherapy) – even if I am now in remission – increase my risk if I get the virus? This depends on the type of cancer and the treatment you have had. Most people make a full recovery after cancer treatment and their immune system either recovers fully or is not affected. If you have been in close contact with someone with a confirmed case of COVID-19, call 111 (England, Scotland and Wales) or 0300 200 7885 (Northern Ireland). Tell the person you speak to about the type of cancer and the treatment you had.
