Breast cancer detected during pregnancy after the birth of the child child, you need to do regular examinations for breast cancer screening. The cause of breast cancer is not yet clear, but some studies have shown that it is related to heredity, and generally the risk of breast cancer in children whose mothers develop breast cancer is usually 2 to 3 times that of the general population. This child would belong to the group of people with a family history of breast cancer. The recommendations for breast cancer screening are as follows: 1. Start screening at the earliest age of diagnosis of breast cancer in the family minus 10 years, but not necessarily earlier than 25 years of age and not later than 40 years of age. For example, if the mother was diagnosed at age 40, the child should be screened at age 30. If the mother was diagnosed at age 30, then screening should begin at age 25. 2. Once you start screening, get a mammogram every year. Women with dense breasts may also consider other imaging options such as ultrasound. 3. After discussing with your doctor, you can have a mammogram or breast MRI every 6 months, alternately. The screening program varies according to each individual’s risk profile and needs to be decided after discussion with your doctor. 4. You can discuss with your doctor whether genetic testing is necessary according to your condition. Usually, you should keep a good mood and ensure enough rest.
