DC therapy

Is DC therapy available on the NHS? , 

My wife has 2 primary cancers, secondary breast cancer which is in her bones and appears to be controlled by the drugs she has been prescribed. She also has cervical cancer which has stopped responding to chemotherapy. The oncologist seems to think we are at the end of the road as far as treatment is concerned and seems to be more interested in making her comfortable than treating the cancer.

I am very keen to find out if she is eligable for trials for DC therapy, or if there are any private clinics who can offer this treatment. 

Many thanks
