Scientists have begun to explore gene therapy as a potential candidate for breast cancer treatments. To give you a clue of what cancer gene therapy is, it's basically programming cancer cells by supplying genes. The genes enter the cancerous cells and have a direct effect on changing the malign cell behaviour.

The therapeutic genes as they are called are delivered to cancerous cells via vectors (or carrier vehicles). Think of them as command delivery officers, who reprogram the bad cells. They basically deliver therapeutic healthy genes to cancerous cells. This is as close to curing the cause of the malign tumour as modern medicine can get.

However, the greatest constraint in gene therapy in general and for breast cancer as well is an optimal delivery vector. There is extensive research seeking to optimize therapeutic gene delivery to cancerous cells combined with other available therapies. It is hoped that gene therapy will limit the toxic side effects for the patient undergoing other treatments.

The future of gene therapy is limitless, but the question is what can be applied nowdays. Either when used in conjunction with another or as a sole form of treatment it can already be applied today. The success rate percentage data is hard to find from good sources, but this therapy is definitely worth of your attention. Through gene therapy it is possible to explicitly target cancerous cells in the body and attempt to destroy them. Also, gene carriers will continuously travel in the blood to search cancer cells.

Genes play a central role in the breast cancer development. Statistics show that hereditary breast cancer makes up approximately 5% to 10% of all forms. Some scientists believe that gene therapy is the most effective means of treating this type of cancer and it may have better impact than any other available treatment.
