How to do a breast self-examination?

　　1) Ask your breast cancer specialist to assess whether you are at high risk; 2) Ask your doctor to make a clinical breast examination plan; 3) Ask for a mammogram once a year over the age of 40; 4) Ask for a breast self-examination on the tenth day after the start of each menstrual cycle or at the same time of the month if your period is irregular.　　The most important part of the screening is the clinical examination and X-ray. X-rays mainly reveal small calcified foci of different sizes, concentrated in one area, and sometimes several calcified foci are found in a small area of the breast. There are also lumps in the mammogram, which are often seen on mammograms. If you find any abnormalities in the breast, you should seek medical attention (mammogram, breast ultrasound, breast biopsy, etc.) to determine if it is breast cancer. Some women think that breast lumps are not important, or they are afraid of embarrassment and do not go to the doctor. Some women mistakenly use some inappropriate health care products, which may delay the disease.
