Skin patches help people reduce their dependence on nicotine, now patches which deliver estrogen into the blood may be a cheaper and safer treatment for prostate cancer than current therapies.
Currently, the main treatment is injections of a chemical to cut levels of testosterone – the driving force of many prostate cancers.
The Imperial College London study in the Lancet Oncology compared patches and injections in 254 patients.
The injections caused adverse side effects including overdosing the liver .. the patches did not.
Researchers say both estrogen and testosterone are very similar chemically so ramping up the levels of estrogen in the body can reduce the amount of testosterone produced – and slow prostate cancer growth.
