New Technique To Study The Genetics Of Breast Cancer

A new technique to study genetic changes that can lead to breast cancer could be one step closer.

The aim of the research is to identify the many undiscovered genes thought to be involved in the early stages of breast cancer.

Ian Ellis, Professor of Cancer Pathology said to develop a technique which would allow the genetic information of many thousands of breast samples to be studied which would be of huge importance in understanding the genetic changes that occur in early breast cancer.”

It is known that breast cancer can develop when the genes in breast cells change and stop working properly.

Inherited defects in genes account for around five to 10 per cent of all breast cancers but all forms of breast cancer have acquired gene defects during their initial stages of development and many of these genes are yet to be discovered.

These defective genes can lead to physical changes in the breast cancer cell resulting in breast cancer.

The earliest physical sign of a normal breast cell developing into one common type of breast cancer is the presence of a flat atypical epithelial (FEA) cell.

Professor Ellis will study the genes in the FEA cells to identify which ones are involved in the very earliest stages of breast cancer.

Pamela Goldberg, Chief Executive, Breast Cancer Campaign, said, “Every year breast cancer kills 12,500 women in the UK.

It is therefore vital that we identify new genes involved in breast cancer development so that women who inherit these faulty genes and are therefore at higher risk of breast cancer, can be monitored at an early stage.”
