There is a persistent myth in medicine that if you feel fine, nothing is wrong. The reality is that many serious health conditions develop silently, without symptoms, until they are advanced enough to cause problems. This is especially true for conditions that affect women differently—including certain cancers, autoimmune diseases, and cardiovascular conditions that present differently in women than in men.

Preventive care exists to catch these conditions early, when they are most treatable. But preventive care only works if you actually get it. Many women fall through the cracks because they do not know what screenings they need, when to start, or how often to repeat them.

Cardiovascular Screening

Heart disease is the leading cause of death in women, killing more women each year than all cancers combined. Yet most women do not think of heart disease as their problem. Cardiovascular screening for women should include blood pressure checks at every annual visit, lipid panels starting in your 20s, and a discussion about other risk factors like smoking, family history, and diabetes.

If you have normal blood pressure and no major risk factors, the American Heart Association recommends a lipid panel every four to six years starting at age 20. If you have risk factors, you may need more frequent monitoring. For blood sugar, the recommendation is to start screening at age 45, or earlier if you have risk factors for type 2 diabetes—which includes being overweight, having a family history, or having had gestational diabetes.

Breast Cancer Screening

Mammography recommendations have been genuinely confusing, with different organizations giving different advice. The current consensus from most major medical groups is that women at average risk should start routine mammograms at age 40 or 50, depending on the organization, and continue every one to two years through at least age 74.

The confusion around mammography timing does not mean screening is not valuable. What is clear is that mammography saves lives. If you are in your 40s or 50s and have not discussed a mammography schedule with your doctor, that conversation is worth having.

For women with higher risk—such as a strong family history of breast or ovarian cancer, genetic mutations like BRCA1 or BRCA2, or dense breast tissue—screening may need to start earlier and include additional imaging like MRI.

Cervical Cancer Screening

Cervical cancer screening has evolved significantly over the past two decades. Current guidelines recommend cervical cancer screening starting at age 21, regardless of sexual activity. Women ages 21-29 should have a Pap smear every three years. Women ages 30-65 have three options: a Pap smear every three years, an HPV test every five years, or co-testing every five years.

HPV vaccination has changed the risk landscape for younger women but does not eliminate the need for screening, since the vaccine does not cover all cancer-causing HPV strains. If you are over 30 and have been vaccinated, you can discuss with your doctor whether co-testing every five years is appropriate for you.

Colorectal Cancer Screening

Colorectal cancer screening should begin at age 45 for both men and women, according to updated guidelines. This was lowered from the previous recommendation of 50, reflecting the concerning rise of colorectal cancer in younger adults. Screening options include colonoscopy every 10 years, stool-based tests like FIT or Cologuard, CT colonography, or flexible sigmoidoscopy.

Colonoscopy remains the gold standard because it can both detect and prevent cancer—if precancerous polyps are found, they can be removed during the procedure before they become cancer.

Bone Health

Osteoporosis is dramatically underdiagnosed in women until a fracture occurs. The USPSTF recommends bone density screening for all women aged 65 and older, and younger women who have risk factors such as low body weight, smoking, long-term steroid use, or a family history of osteoporosis-related fractures.

The reason to catch low bone density early is that you can slow its progression with weight-bearing exercise, adequate calcium and vitamin D, and in some cases medication. Waiting until a fracture happens to diagnose osteoporosis means you have already lost significant bone mass that could have been preserved.

Preventive care is not about finding disease for its own sake. It is about catching what is treatable before it becomes less treatable. If you have not had a physical exam and basic screening panel in the past year, that is a reasonable thing to prioritize—regardless of how good you feel.
