According to Cancer Research UK, most cancer pain is caused by the tumour pressing on bones, nerves or other organs in the body.
“Sometimes pain is due to your cancer treatment. For example, some chemotherapy drugs can cause numbness and tingling in your hands and feet,” explains the charity.
“Or they might cause a burning sensation at the spot where you have the drug injection.”
It adds: “Radiotherapy can cause skin redness and irritation.”
