Recent reports and guideline changes suggest some medical tests should be delayed, avoided or done less often:

Mammogram: Most women don’t need a mammogram in their 40s, and they should get one every two years starting at 50, according to the U.S. Preventive Services Task Force, a government-appointed but independent panel.

The task force’s advice is controversial, and other national guidelines recommend that screening start at 40.

Pap smear: Most women in their 20s can have a screening test for cervical cancer every two years instead of annually, say new guidelines from the American College of Obstetricians and Gynecologists. And screening with a pap smear shouldn’t start until age 21. Other national guidelines vary slightly.

Prostate cancer: Though many men get tested, most groups don’t support routine screening for prostate cancer. The American Cancer Society says doctors should have a frank discussion of the benefits and limitations at age 50 with men at average risk.

Heart tests: A recent study suggests too many low-risk patients are given angiograms to check for heart disease. The researchers say doctors could do a better job of choosing who really needs the exam.

Cesarean sections: A government panel says too many women don’t get the chance to avoid a repeat cesarean delivery; only 1 in 10 women who have a C-section deliver their next baby vaginally.
