78 Citations | Accurate and early detection of breast cancer can ensure long-term surviving for the patients. |
| Significant differences in the risk of having future contralateral breast cancer according to method of detection were not observed. Breast cancer detected by mammography screening is an independent prognostic factor in breast cancer and is associated with a more favorable survival rate as well as in long-term follow-up. | |

At what age early breast cancer is diagnosed?5 answersEarly breast cancer is typically diagnosed in patients aged 40 years and younger, with a median age at diagnosis reported to be around 36 years. However, studies have shown that early breast cancer patients can also be older, with a mean age at diagnosis of 51.2 years and 55.9% of patients being aged 50 years or older. Additionally, a study categorized patients into different age groups, with group Y aged ≤35 years, group M aged >35 and ≤45 years, and group E aged >45 years, showing that very young age (≤35 years) did not independently predict poor prognosis in early-stage breast cancer. Therefore, early breast cancer can be diagnosed across a wide age range, but the median and mean ages reported in the studies suggest that it is often diagnosed in younger individuals.
Mammograms and overdiagnosis of breast cancer?5 answersMammograms can lead to overdiagnosis of breast cancer, which refers to the detection of cancers that would not have caused harm or symptoms in a person's lifetime. The rate of breast cancer overdiagnosis is still a topic of debate. However, recent studies have provided estimates of overdiagnosis rates. One study by Ryser et al. found that in a biennial screening program for women aged 50 to 74, approximately 1 in 7 cases of screen-detected cancer were estimated to be overdiagnosed. Another study by Chiu et al. highlighted the importance of considering the balance between benefits and harms of mammography screening, especially in low- and middle-income countries where breast cancer incidence is increasing. These findings emphasize the need for informed decision-making and counseling about the risks and benefits of mammography screening to facilitate shared decision-making.
Why is it important to diagnose and screen for breast cancer early?5 answersEarly diagnosis and screening for breast cancer are important because they can significantly improve the chances of survival and reduce treatment costs. Early detection allows for timely initiation of treatment, which is more effective and less expensive. Screening programs for breast cancer have been recommended and applied worldwide, including in China, to reduce mortality rates. However, the benefits of screening have been a topic of debate, with some studies suggesting that the effectiveness may vary depending on the type of cancer being screened. Artificial intelligence techniques, such as convolutional neural networks and machine learning algorithms, have shown promise in early breast cancer diagnosis, providing reliable results and the potential for widespread accessibility. These advancements in technology can aid in the early detection of breast cancer, leading to improved outcomes for patients.
