Early detection tests for breast cancer
In the ongoing fight against breast cancer, doctors are now focusing on a more personalized approach to screening. This shift aims to improve early detection and prevention strategies based on individual risk profiles.
Breast cancer screening refers to checking the breasts for signs of cancer before any symptoms appear. A mammogram, a scan that uses X-rays to take an image of the breast, is one of the best tests for finding early signs of breast cancer. Regular screening, therefore, is the most important tool for early detection.
However, breast cancer can have no obvious symptoms or signs in the breast tissue. This is where personalized risk assessment comes into play. These tools help doctors estimate a person's potential risk of developing breast cancer by analyzing individual data such as age, race, ethnicity, and family medical history. The results of these assessments give doctors a general indication of a person's breast cancer risk.
One such tool is the Tyrer-Cuzick score, which some doctors may use to assess breast cancer risk. Other models, like the AI-based system developed at Washington University, analyse mammogram images directly to produce more accurate five-year risk predictions. These systems integrate with existing mammography and generate an absolute risk score that helps clinicians decide when to intensify screening, refer patients to specialists, or consider preventive measures.
Personal risk is a combination of many factors, and no single risk factor or group of risk factors guarantees cancer development. Main risk factors for breast cancer include increasing age, reproductive history, personal history of breast cancer or related conditions, inherited genetic mutations, family history of breast or ovarian cancer or disease, dense breast tissue, previous radiation therapy, some drugs like diethylstilbestrol, overweight or obesity after menopause, sedentarism, alcohol use, hormone use, and certain types of birth control pills.
It's important to note that early signs and symptoms of breast cancer can vary widely, and some people may have no signs or symptoms at all. Anyone who has concerns about their risk of breast cancer, experiences symptoms, or believes they may be at high risk should contact a doctor. If a suspicious area is found, a biopsy—a procedure where a bit of tissue from the area is removed for laboratory inspection—may be recommended.
Other tests such as breast tomosynthesis, contrast-enhanced mammography, molecular breast imaging, electrical impedance imaging, and positron emission mammography may be recommended in some cases. Additionally, ultrasound and MRI, which uses radio frequencies and magnets to make a very detailed picture of the breast tissue, may also be used in certain situations.
Managing lifestyle factors may also help reduce the risk of breast cancer. This includes maintaining a healthy weight, regular exercise, limiting alcohol consumption, and avoiding hormone replacement therapy.
In conclusion, personalized breast cancer screening is a significant step forward in the fight against breast cancer. By moving beyond one-size-fits-all approaches, this new method enables a more individualized process that enhances early detection and prevention strategies based on personalized risk profiles. Early detection of breast cancer is crucial as it is most treatable in its earliest stages, and screening can help reduce deaths from breast cancer and increase life expectancy, 5-year survival rates, and decrease the number of people with late-stage cancer at diagnosis.
