Vital breast cancer research makes discovery

Researchers at the University of Pennsylvania believe they have pinpointed the protein, P-Rex1, which scientists have found in great abundance in over 60 percent of breast cancer cases, according to In greater numbers, the protein seems to inhibit metastasis and allow the cancer to spread. The discovery could help lead to new treatment options for breast cancer patients.

The research is uplifting news for breast cancer patients and their families as it could possibly lead to less invasive treatment and localized therapy. The study results allow doctors a different perspective to find out why some patients respond well to traditional treatment options while others don't.

"We identified a downstream target of the ErbB receptors which seems to be crucial for cancer cell proliferation," said Dr. Marcel Kazanietz, professor of pharmacology at University of Pennsylvania's School of Medicine in a statement, according to the news source.

Dr. Kazanietz believes pinpointing the start point for metastasis and the protein that allows it to spread and grow are incredible breakthroughs that will help breast cancer patients in the near future.

According to the American Cancer Society, excluding skin cancer, breast cancer is the most common form of cancer among American women.
