Who Should Get Screened?

The need for cancer screening varies depending on factors such as age, family history, and lifestyle. It's essential to discuss your individual risk factors with your doctor to determine the most appropriate screening schedule for you.

Common Cancer Screenings

Here's a breakdown of common cancer screenings and their recommendations:

Breast Cancer

Average Risk:

- Women aged 40-49: Shared decision-making with their doctor about the potential benefits and risks of screening mammography.

- Women aged 50-74: Mammography every 1-2 years.

- Women over 75: Offer screening if life expectancy is 10 years or more.

Moderate Risk: First-degree relative with breast cancer but no genetic syndrome.

High Risk: MRI as an adjunct to mammography for women with a lifetime risk of breast cancer greater than 20%, BRCA mutations, or a history of chest radiation between ages 10-30.

Cervical Cancer

Women aged 21-29: Cervical cytology (Pap smear) every 3 years.

Women aged 30-65: HPV/cytology cotesting every 5 years or cytology alone every 3 years.

Women over 65 or with a total hysterectomy: No screening necessary unless they have a history of abnormal results or are at high risk.

Colorectal Cancer

Adults aged 45-75: Screening with one of the following:

- Stool-based tests (FIT, fecal immunochemical test, or Cologuard)

- Colonoscopy every 10 years

- Flexible sigmoidoscopy every 5 years with a home fecal immunochemical test (FIT) every year

Lung Cancer

Adults aged 50-80 with a smoking history of 20 pack-years or more: Annual low-dose CT scan.

Prostate Cancer

Men aged 50 and older: Discuss screening with their doctor, considering their individual risk factors and preferences.

Men aged 45-49: Consider screening if they are at increased risk due to family history or other factors.

It's important to note that these are general guidelines, and individual circumstances may vary. Always consult with your doctor to determine the most appropriate screening schedule for you.
