Exploring nanoparticle therapies in breast cancer treatment

Abstract

Breast cancer is one of the leading cancers in women, which may occur at any age. Traditional treatments such as chemotherapy, radiotherapy, or surgery are being replaced by nanoparticle-based therapies. As nanoparticle therapies are next-generation treatments, they have fewer side effects than other treatments. Nanoparticles can carry medicines directly to the cancer cells, which helps to reduce damage to the normal tissues and makes the treatment more specific. Different types of nanoparticles are: gold particles, metallic and metal-oxide nanoparticles, magnetic nanoparticles, liposomes, nanobubbles, and polymer-based particles, which can carry drugs and respond to changes in tumor characteristics like pH, enzyme, light sensitivity, and others. These particles work in different ways, for example, stopping cancer cell growth, blocking cancer cell signaling, and helping the immune system against cancer cells. However, there are challenges with nanoparticle use in breast cancer treatment, but the future of this can be very promising with focused research work, as the therapy has higher effectiveness in Oncogenic cells.
