Understanding Cancer at a Molecular Level

Cancer cells differ significantly from healthy cells in that they proliferate uncontrollably and can spread to other parts of the body, a process known as metastatic dissemination. The initial understanding of cancer involves recognizing tumorigenesis, where normal cellular organization breaks down, leading to excessive and misplaced cell growth. This disorganization disrupts the functions of tissues, rendering conventional treatments like surgery ineffective if the cancer has spread. Such insights underline the critical importance of studying cancer on a molecular level to develop effective treatment strategies.
