Breast cancer is considered as a fatal disease and it is known to be the number one cause of cancer fatality in women. According to American cancer society, an estimated 1.3 million new breast cancer instances are detected every year which includes 465,000 deaths. In order to productively tackle this devastating disease, we must push innovative scientists to research cancer at its most basic stage. In other words, breast cancer research work should be done at its molecular stage. Also, besides the governments, private organizations must offer flexible budget to scientists who will be doing breast cancer research work.
Proper financial support of breast cancer investigation projects; can not only lead to better prevention methods but it can also assist towards earlier detection techniques and new anticancer drugs and cure.
Not so long ago, scientists who are working towards breast cancer research project, have created and successfully tested a breast cancer vaccine which is possibly to cure women with treatment – resistant HER2 – positive breast cancer and thus be able to avoid cancer remission. Breast cancer scientists look forward to use HER2 DNA vaccines for cancer-free women, in order to avoid early development of these tumours. Today therapies such as trastuzumab and lapatimib are used towards treating breast cancer patients. However, it was lately noticed that a huge number of patients develop a resistance in trastuzumab and lapatimib. HER2 receptors are identified to promote a specifically aggressive kind of cancer that affects an estimated thirty percent of breast cancer patients. The latest breast cancer vaccine is created by the body’s own cells. It gives a cancer combating gene into cells, which subsequently produce immune system proteins and also cancer ? fighting cells.
According to the lead researcher Wei – Zen Wei, a professor of immunology and microbiology at the Karmanos Cancer Institute, the vaccine is made by using so – called naked DNA from genes that makes the HER2 receptor. This DNA is mixed with an immune stimulant. The method involved in the making of the vaccine, is called as electro oration.
In this process, pulses of electricity were used in order to inject the vaccine into the leg muscles in mice. The genes acted towards the cells, which then created HER2 receptors that led to activation of antibodies and immune cells called Killer T cells.
