Going to the doctor when you're sick is a no-brainer. But going when you're perfectly fine can be a lifesaver. "People who schedule routine visits get the best preventive services, and that sets the stage for success," says Jonathan Temte, M.D., Ph.D., associate professor of family medicine at the University of Wisconsin School of Medicine and Public Health, in Madison. Screening tests are crucial: Your chances of beating virtually any condition are much greater when you catch it in its earliest stages—when it's most treatable or even curable. Use this chart as a guide, but discuss your personal history and specific needs with your doctor. 
Blood Pressure

When to go: All adults should have their blood pressure checked every two years (every 6-12 months if you have hypertension).
How to prep: Arrive with five minutes to spare and take a few deep breaths while you wait. Stress and anxiety can falsely inflate the results.
What comes next: A healthy pressure is 120/80 or less, 140/90 is considered high, and in between is "prehypertension." Since high blood pressure ups your risk of stroke and heart attack, if you have it your doctor will likely tell you to lose weight, exercise, change your diet, limit alcohol intake, and quit smoking (which all lower blood pressure) before putting you on medication.
Colorectal Cancer

When to go: Men and women need an initial screening at age 50 (21 if you have a family history). The gold standard is a colonoscopy every 10 years (more often if at high risk). A flexible sigmoidoscopy is a substitute, but colonoscopy reaches higher in the colon where cancer is more often found in women.
How to prep: For a colonoscopy, maintain a special liquid diet and drink a colon-clearing solution for one to two days. A sigmoidoscopy requires only two enemas the morning of the appointment.
What comes next: If polyps are spotted, they're removed and biopsies are taken of anything abnormal. Questionable spots in sigmoidoscopy are looked at more closely with a colonoscopy.
When to go: An overall lipoprotein profile is recommended at age 20 and every five years after that. Children with a family history of high cholesterol can be tested too.
How to prep: It's a simple blood test, but you need to fast for 10-12 hours before, so make it easier on yourself by scheduling an early morning appointment.
What comes next: Total cholesterol should be less than 200 mg/dL; LDL (bad) less than 100; HDL (good) higher than 40; triglycerides below 150. High total and LDL levels cause buildup on artery walls and block oxygen and blood flow, increasing heart attack risk. Your doctor may suggest changing your diet, increasing activity, and a retest in 3 to 6 months before considering medication.
