There are different ways of taking these drugs, depending on your cancer. It could be by injection, through a drip, as a tablet or even as a cream on the skin. You might be offered immunotherapy in combination with other treatments.
How long does it take?
Treatment could be every day, every week or every month - it depends on your cancer. You might have treatment in cycles - with breaks in the treatment so your body can rest, respond to the treatment and build up healthy cells.
Your doctor or specialist nurse can tell you more about immunotherapy and whether it might be an option for you.
