Our DNA does not preclude us from any disease. Its all about when the epithelial cell cannot turn itself off. By removing the BRCA gene then you only eliminate the risk of developing breast cancer induced by the BRCA gene. There are still numerous other ways to get cancer (whether breast or not)
What makes a good cell turn to cancer? Well there are 3 ways:
1.Radiation (sun, nuclear energy and nuclear medicine, Hiroshima, etc)
2.Virus (ie: HPV's; mostly eradicated from mankind - except in Africa where unknown diseases are prevalent)
3.Environment - combustion, cigarettes, exhaust; nutritional deficiencies, hormonal, ---Anything that we metabolize either by eating or inhaling.
So, removing the BRCA gene may lessen the risk of developing BRCA induced breast cancer, but cancer has other ways of developing. I am sure the family that has the gene removed knows that their risk is lessened, but aware their are other triggers.
