What Are the Different Types of Cancer Screening?

Tumor screening is an important way to detect cancer and precancerous lesions early. Various blood test indicators in physical examination, B-ultrasound, X-ray, anorectal digital examination, Pap smear, breast molybdenum palladium in gynecological physical examination are common methods for screening tumors.

1,

1. A history of long-term smoking or exposure to toxic and harmful gases. Regular chest x-ray examinations and combined examination of tumor markers (CEA, SCC, NSE, TPA).

2. Middle-aged women have regular infrared breast scans and combined tumor markers (CEA, CAl5-3, TPA). The mass was obviously examined for breast cancer by breast puncture.

3, women over 35 years of age and human papillomavirus infection (HPV) are at high risk for cervical cancer, and should undergo regular vaginal exfoliation cytology examinations, or thin-layer cell preparation techniques (TCT) and tumor markers (SCC, CAl25, TPA) joint inspection. Pathological biopsy was performed under colposcopy to confirm the diagnosis.

4. If you are in a high incidence area of liver cancer or have chronic viral hepatitis (especially hepatitis B and C), it is recommended that you do a combined examination of the five markers of ultrasound, hepatitis B and tumor markers (AFP, AFU).

5. In the high incidence area of nasopharyngeal carcinoma, regular virus tests should be performed, if necessary, puncture cytology and pathological biopsy to confirm the diagnosis.

6. Have a history of chronic gastric disease for gastroscopy and tumor markers (CEA, CA72-4, CA19-9, CA242) combined examination. Biopsy of gastric mucosa tissue under electron microscope confirmed the diagnosis.

7. Pancreatic cancer is easily misdiagnosed clinically. Suspected pancreatic cancer should be examined by B-ultrasound and tumor markers (CEA, CAl9-9, CAl25, CA50).

8. Those with persistent blood in the stool were selected for combined examination of tumor markers (CEA, CAl9-9, CA50). Rectal tissue biopsy confirmed the diagnosis.

9. Combined examination of B-ultrasound and tumor markers (CEA, CAl25, CAl9-9) for suspected ovarian cancer; laparoscopic biopsy of ovarian tissue to confirm the diagnosis.

10. Middle-aged and elderly men are susceptible to prostate cancer and need to be tested for tumor markers (PSAl).

11, if you often have dizziness, low fever, pale, anemia, enlarged liver, spleen and lymph nodes, bleeding or bleeding points, blood tests and blood cell smears are the most convenient and practical. If the blood image indicates a malignant tumor of the blood system, a diagnosis can be made by simply taking a bone marrow for cytology.

12. Tumor marker heat shock protein 90 (Hsp90) is positively correlated with tumor malignancy. As long as a drop of blood is drawn, you can detect whether you have cancer.
