According to the world's latest cancer data released by the International Agency for Research on Cancer (IARC) of World Health Organization on 4 February 2021, breast cancer in women has overtaken lung cancer as the most common cancer, with an estimated 2.3 million new cases (11.7%), followed by lung cancer (11.4%). This is the first time that breast cancer has surpassed lung cancer to become the "world's largest cancer". The growth rate of breast cancer incidence in China is twice that of the global average growth rate, ranking first in the world.

In order to reduce the incidence of breast diseases, many manufacturers at home and abroad have developed intelligent monitoring bras, which use dozens of NTC thermistors to monitor the temperature of the mammary glands in real time, and send relevant data to the mobile APP through Bluetooth or WiFi, which is convenient for users to view. Intelligent monitoring bra uses NTC thermistors to determine and analyze the temperature of different locations of the mammary glands, in this way, cancer monitoring is carried out when the temperature changes suddenly, and the data will be sent to the mobile APP in real time for comparison and analysis with the data in the database, so as to check the health of mammary glands. If there is an exception, a risk assessment is performed and the user is prompted for further checks.

Compared with the existing mammary gland monitoring methods, the intelligent monitoring bra can save the time cost of users and does not need to go to the hospital or related medical institutions for examination; And real-time monitoring of mammary glands, so that users can better understand their own mammary glands situation; The close-fitting design can better obtain temperature information and ensure the accuracy of monitoring.

CB series SMD type NTC thermistor developed newly by EXSENSE Electronics Technology Co., Ltd., it has the characteristics of small size, leadless, good bending ability, which is suitable for high-density surface mounting, so it is widely used in intelligent monitoring bras, smart bracelets, TWS Bluetooth headsets and other wearable smart devices.
