Treatments provided by Dr Mark Tuthill

Having a diagnosis of cancer can be a highly stressful and difficult time for patients and their families. Dr Tuthill uses a patient-centred approach to help those suffering from cancer to review and understand their treatment options.


Chemotherapy drugs are used to kill cancer cells and can be used to prevent cancer from returning after breast, bladder, lung, and testes surgery or to treat recurrent cancer.


Immunotherapy treatments for cancer are drugs which harness the immune system to kill cancer cells. Cancer immunotherapy has revolutionised the treatment of many forms of cancer including lung cancer, kidney cancer, bladder cancer, skin cancer and may become a treatment for some forms of breast cancer.

Cancer growth inhibitors

Cancer growth inhibitors are used to treat cancers of the prostate, lung, kidney and breast. Many cancer growth inhibitors target specific cancer mutations within the cancer cells such as Herceptin in breast cancer, EGFR in lung cancer, cancer growth receptors in kidney cancer, and the testosterone receptor in prostate cancer.

Hormone therapy

Breast cancer can be treated by lowering the female hormone oestrogen, and prostate cancer can be treated by reducing the male hormone testosterone. Often it is possible to combine cancer growth inhibitors with hormone therapy. The side-effects of these treatments can be minimised by using various techniques.
