Researchers shed light on the advanced potential of nanotechnology in caring for breast cancer patients. The researchers explained how nanoparticles reshape the diagnosis and treatment of breast cancer, allowing early detection, careful delivery of medicines, and innovative strategies to combat aggressive sub -types of tumors.
The nanoparticles are very small molecules with a diameter of 1 to 100 nanometers, and they are thus thinner thousand times than human hair.
Researchers from the University of Sichuan in China reviewed research related to this technology and their review was published in the MED Com magazine (Medcomm -Biomateries and Applications) on May 5 and wrote about the Yurrick Alert website.
Breast cancer and its challenges
Breast cancer is the most common types of cancer among women, whether in developed or developing countries, and several factors cause the disease, including lifestyle and heredity.
Breast cancer occurs when some cells begin to grow abnormally as a result of a mutation or a change in the genetic substance, then spread to the rest of the breast areas and to the lymph nodes, and from there to other parts of the body. Breast cancer usually begins in the cells of channels that produce milk, and may start with glandular tissues in the breast.
Breast cancer is a major health challenge all over the world. According to the World Health Organization, there were 2,261 million new negative triple breast cancer patients around the world in 2020, ranked first among all malignant tumors.
The negative breast cancer, which lacks the expression of estrogen receptor, the receptors of the hormone (PROGESTERONE RECEPTOR) and the receptors of the human skin growth factor (Human Epidermal Growth Factor Receptor 2), between 15% And 20% of all cases of negative triple breast cancer. This type of cancer is particularly aggressive, with a death rate of 40% in the advanced stages during the first five years after the diagnosis.
What are the potential of nanoparticles?
Current diagnostic methods, such as X -ray and tissue firmness, are limited in early detection and careful diagnosis. Traditional treatments, such as surgery, chemotherapy, and radiotherapy, are often accompanied by severe side effects and limited effectiveness in the treatment of advanced or metastatic cancer, which is cancer formed in another region separate from the first region in which the initial cancer arose, for example cancer may start in the intestine and then transmit to the liver. In light of these challenges, nanotechnology provides a glimmer of hope.
Nanoscopic particles have shown promising potential to improve diagnostic imaging. For example, nanoparticles can be used as nanoparticles as auxiliary factors in diagnostic photography as these particles accumulate in oncology sites and produce strong contrast effects, enabling early and more accurate detection of the tumor.
Nanoscopic particles also play a decisive role in the treatment of breast cancer, as they can be designed as advanced nanoparticles to improve the supplications of the drug, its stability and connection to the affected area. For example, nanoparticles associated with antibodies can specifically connect chemotherapy to cancer cells, which reduces side effects on healthy tissues.
Hypervision and heat optical therapy is provided using nanoparticles as non -surgical alternatives to traditional treatments, as it generates heat to destroy cancer cells. Dynamic optical therapy, which combines sensitive medications for light and light, is also enhanced by nanoparticles, which improves the delivery of the drug and reduces side effects.
Moreover, the connection of nucleic acids using nanoparticles carries great potential for breast cancer treatment at the genetic level. RNA can be connected to the cancer cells to regulate genetic expression, inhibit carcinogenic genes, or enhance the expression of genetic genes.
