Can a blood test detect breast cancer?

Can a blood test detect breast cancer? No. If breast cancer is suspected, a blood test can only detect whether there is an abnormality in the white blood cells, but cannot confirm that it is any cancer. Only after diagnosis, a sample of the diseased tissue is taken for culture testing to confirm the diagnosis. Below we introduce the examination methods for breast cancer.

1. Self-examination

(1) Examination time: between the 5th and 10th day after the end of menstruation each month, when breast tissue is the softest and the disease detection rate is high; menopausal women can have an examination on a fixed day each month.

(2) Inspection method:

a) Stand in front of a large mirror with your hands hanging naturally, and observe whether there are any changes in the shape and size of your breasts.

b) Raise your hands behind your head, straighten your chest and observe whether the surface of your breasts is sunken or wrinkled. Turn your body left and right and observe your breasts from different angles, such as the front and side.

c) Observe the nipple and pinch it gently with your thumb and index finger. For some women, a small amount of white discharge is normal. If there is bleeding or abnormal discharge, consult a doctor immediately.

d) Lie down on a flat surface, place a small pillow or folded towel under one shoulder, and place the hand on the same side behind the head. Use the other hand to touch and press the breast to check for swelling or lumps. The examination range must end at the armpit. Repeat the same steps on the other side.

2. Regular physical examination

Regular physical examination means going to the hospital and having an experienced doctor who specializes in the diagnosis and treatment of breast diseases do a comprehensive palpation examination again. According to age, it is recommended that women aged 20 to 50 have a regular check-up once a year, and women over 50 should have a breast examination every six months.

3. Auxiliary examination

The most commonly used methods for breast examination include mammography, ultrasound, CT breast ductography, ductoscopy, puncture biopsy of lumps and biopsy of sections, etc. The specific examination items should be determined by the doctor according to the needs of the patient.
