- Prostate-specific antigen (PSA) test: for prostate cancer (men over 50)
- Low-dose computed tomography (LDCT): for lung cancer (current or former smokers over 50)
- Epidermal growth factor receptor (EGFR) mutation test: for lung cancer (never or former light smokers)
Recommended Screening Ages and Frequency
The recommended screening age and frequency for specific cancers vary depending on factors such as age, gender, personal risk factors, and family history. Here are general guidelines:
- Cervical cancer: Pap test every 3 years starting at age 21
- Breast cancer: Mammogram every 1-2 years starting at age 40
- Colorectal cancer: Colonoscopy every 10 years starting at age 45
- Lung cancer: LDCT scan annually for current or former smokers over 50
- Prostate cancer: PSA test every 1-2 years starting at age 50
Importance of Regular Check-Ups and Follow-Up
Regular cancer screenings are essential for early detection, timely treatment, and improved outcomes. It is important to attend scheduled screenings and follow-up appointments as recommended by your doctor. If a screening test detects any abnormal findings, further tests may be required to confirm a diagnosis.
