Recently, scientists have developed a new device for the early detection of breast cancer - "electronic skin." It can feel some small bumps that are missed when a finger detects a breast. Detecting the size and shape of the mass will help early diagnosis of breast cancer. The researchers tested the new device on a silicone breast model. Related articles are published in the journal ACS Applied Materials & Interfaces.
The researchers point out that early diagnosis of breast cancer is very important for women's health, but small tumors have never been easily detected. Commonly used detection methods, including nuclear magnetic resonance and ultrasonic waves, are highly sensitive but expensive. Mammograms are also not perfect, especially when it is used to test young women or women with dense breast tissue.
The initial steps in a clinical breast examination are performed by medical staff, but usually cannot be detected until the length of the mass reaches 21 mm. If the size of the mass is detected at half the size above, the patient's survival rate will increase by 94%.
Currently, there are some devices that can mimic manual detection, but their image quality is poor and the shape of the lump cannot be determined. The shape of the lump can help the doctor determine if the lump is cancerous. Scientists involved in such research want to fill this gap.
The "electronic skin" they invented consists of nanoparticles and polymers that sense and reflect small objects. To test how the device is used on the patient, they implanted a lump-like object in a silicone breast model and then pressed the device against the model with the same pressure that the clinician used to detect the patient's breast. As a result, they found a "stalle" of a 5 mm long lump at a depth of 2 cm.
The researchers said the device can also be used to detect early detection of other cancers, including melanoma.
