问题     Mike Slabaugh doesn’ t have a stomach. Neither do his 10 cousins. Growing up, they watched helplessly as a rare hereditary stomach cancer killed their grandmother and some of their parents, aunts and uncles. Determined to outsmart the cancer, they turned to genetic testing. Upon learning they had inherited Grandmother Golda Bradfield’ s flawed gene, these were their options: Risk the odds that they might not develop cancer, with a 70 percent chance they would; or have their stomachs removed. The latter would mean a challenging life of eating very little, very often.
    All the cousins chose the life-changing operation. Doctors say they’re the largest family to have preventive surgery to protect themselves from hereditary stomach cancer. "We’re not only surviving, we’ re thriving," said Slabaugh 16 months after his operation at Stanford University Medical Center in Palo Alto.
    Advances in genetic testing are increasingly giving families with bad genes a chance to see the future,  sometimes with the hope of pre-emptive action. People have had stomachs, breasts, ovaries, colons or thyroid glands removed when genetic tests showed they carried a defective gene that gave them a high risk of cancer.
    But what about people whose families don’ t have these rare, but powerful genetic defects? Experts  say that someday, doctors may do DNA tests as routinely as they check cholesterol(胆固醇) levels  now, spotting disease risks that can be lowered. That day isn’t here yet, but progress is being made.
Who will benefit more from advances in genetic testing?
