NEW YORK |
NEW YORK (Reuters Health) ? Screening for mutations in a gene famous as CHEK2 competence assistance establish a woman?s contingency of breast cancer if a illness runs in her family, Polish scientists suggested Monday.
A lady harboring a CHEK2 mutation, for instance, would have a 34 percent risk of building breast cancer if her mom or sister had a disease, they estimate.
But U.S. experts pronounced a exam isn?t prepared for primary time yet, and emphasized that Polish women competence be opposite from Americans.
?It would be beforehand to tell women that we should all go out and get CHEK2 screening,? pronounced Dr. James P. Evans, editor-in-chief of a American College of Medical Genetics? biography Genetics in Medicine.
Still, he called a investigate ?a good start.?
Women with a questionable settlement of breast or ovarian cancer in a family are already speedy to get screened for mutations in a BRCA 1 and 2 genes that advise of a heightened growth risk.
But if those tests come adult empty, doctors don?t have most to offer, Dr. Diana Petitti, of a Arizona State University in Phoenix, told Reuters Health.
?This does paint an vicious breakthrough,? she pronounced of a new findings. ?But this is a margin where riposte is critical.?
The Polish researchers tested a genes of scarcely 7,500 women with breast cancer who didn?t have BRCA 1 mutations.
They found that 3 percent had a certain form of turn in a CHEK2 gene.
Among women but breast cancer, reduction than one percent harbored mutations. Although CHEK2 has been tied to cancer before, it wasn?t transparent what purpose cancer in a family played. When a group asked a women either they had any influenced relatives, those whose mom or sister had had breast cancer were during top risk.
About one in 8 American women ? or some 12 percent ? will get breast cancer during some indicate in their lives.
In Poland, that figure is usually 6 percent, Dr. Cezary Cybulski of a Pomeranian Medical University in Szczecin and colleagues write in a Journal of Clinical Oncology.
From their findings, they guess that a lady with a CHEK2 turn has a risk of 20 percent. If she also has a mom or sister with breast cancer, her risk jumps to 34 percent, and to 44 percent if a second-degree relations is also sick.
?CHEK2 turn screening detects a clinically suggestive risk of breast cancer and should be deliberate in all women with a family story of breast cancer,? a researchers say.
According to Evans of a American College of Medical Genetics, such tests are already available, expected for reduction than $100.
While that competence sound cheap, it adds adult quickly, he added. ?If we give this exam to all women who have a tighten relations with breast cancer, we are now articulate about a outrageous expenditure,? Evans told Reuters Health.
At this point, he said, women with a family story of breast cancer would be improved off articulate to their doctor, or a genetic counselor, to find out what options they have.
Those who have BRCA 1/2 mutations, for instance, competence cruise carrying their breasts and ovaries removed, or holding certain medications, to wand off tumors.
Petitti also struck a discreet note about a new test.
?We are only not there yet,? she said. ?It?s a matter of investigate during this point.?
