Challenges and Future Directions in Mammography
Mammography has revolutionized the early detection of breast cancer, but it is not without its challenges. Despite advances in technology, mammography still faces limitations that affect its effectiveness and comfort for patients.
Current Challenges in Mammography
Radiation exposure and tissue compression are two significant challenges in mammography. Radiation exposure can be a concern for patients, as it raises the risk of developing cancer over time. Tissue compression, on the other hand, can cause discomfort and pain during the imaging process. Additionally, mammography can be less accurate in detecting cancer in dense breast tissue, leading to false negatives and delayed diagnosis.
Mammography radiation exposure can vary depending on the machine used and the imaging protocols followed. However, the average exposure from a mammogram is relatively low, equivalent to about 0.4 millisieverts (mSv). For comparison, a typical chest X-ray exposes a patient to about 10 microsieverts (μSv).
Tissue compression is a necessary aspect of mammography, as it helps to flatten the breast tissue and provide a clear image. However, this compression can be painful for some patients, particularly those with sensitive breasts.
