Woman covering her breastAccording to ABC 7 men have a one-in-two chance of getting a diagnosed with cancer, while for women, it’s one in three. But for some, cancer is inevitable because of genes that are passed from one generation to the next. It’s a riddle that researchers are trying to solve.

In three generations of Johnson women, only two have never gotten breast cancer.

“My aunt was diagnosed twice, then my middle sister, and she was diagnosed twice,” said Paulette Johnson, a breast cancer survivor.

The University of North Carolina’s Kristy Lee collects pedigree information, or family information, combined with blood and DNA. This tool may identify the genetic building block that flips on the Johnson’s breast cancer switch.

“These tragic stories of cancer in a family can be caused by a single change in one of those building blocks,” said Dr. Jim Evans, director of UNC Clinical Cancer Genetics Services.

Experts say rare and less common gene variants may cause inherited risk for some diseases. Researchers have identified over 100 families whose pedigree suggests a link to cancer.

Women with these genetic mutations are put at an 85 percent risk of developing breast cancer sometime in their life compared to the 10 to 12 percent risk in the rest of the population. If that specific mutation is found, scientists could test and ID at-risk folks before they get sick.

“There have been eight mastectomies. I don’t want them to go through that,” said Johnson.

Breast cancer remains one of the most curable forms of cancer when diagnosed early. Dr. O’Toole explains to his breast augmentation patients the importance of following the American Cancer Society’s recommendations for monthly breast self-examination and yearly mammograms after 40 years of age. Patients with significant history of breast cancer are advised to follow their primary care doctors recommendation for frequency of mammograms.
