New drugs for breast cancer affected women

New Treatment for Breast Cancer patients

Research by Wellcome Trust Sanger Institute, UK shows that 1 out of 5 women suffering from breast cancer can be treated by PARP inhibitors. This makes it 10,000 women a year in UK.

Once approved as a cancer-drug, it can potentially change the lives of many women patients all over the world.

PARP inhibitors are also believed to treat common types of breast cancer.

What are PARP inhibitors?

PARP (Poly ADP ribose polymerase) inhibitors repair the DNA structure in faulty genes and suppress the tumour. Olaparib is a PARP inhibitor that is used to treat ovarian cancer.

The drug's effect on cancer

More types of breast cancer can now be treated by PARP inhibitors.

These forms of the cancer are biochemically comparable to the rare cases of mutation of BRCA genes. Without mutation, BRCA1 and 2 genes are tumour suppressing genes or caretaker genes.

If the clinical trials are successful, the drug can also be helpful in treating other forms of cancer like prostate cancer.
