Abstract

Cancer is a major cause of death worldwide, with over ten million fatalities reported each year. Common cancer treatments involve surgical procedures, radiation, and chemotherapeutic drugs. However, these treatments can cause toxicity in patients and may also harm healthy cells. As a result, scientists are exploring ways to selectively target cancer cells without damaging healthy cells. Intratumor heterogeneity, which refers to the diversity of cancer cells within a tumor, poses a significant challenge to effective cancer treatment. Nevertheless, advancements in diagnostic technologies and a better understanding of the molecular basis of tumors can potentially enhance the treatment of different types of cancer.

Cancer is a condition in which cells grow uncontrollably and evade cell death, leading to the formation of a tumor, except in the case of hematological cancers. The tumor grows by developing new blood vessels and eventually gains the ability to spread to other areas of the body, resulting in metastasis and death. Cancer can be caused by genetic mutations resulting from either inherited or environmental factors. For localized and nonmetastatic cancers, surgery and radiotherapy are the primary treatments. However, for metastatic cancers, chemotherapy, hormone therapy, and biological therapy are used. Chemotherapy works by inhibiting the growth of rapidly dividing cells, which is a characteristic of cancer cells. Unfortunately, chemotherapy also affects normal cells that have a high proliferation rate, such as hair follicles, bone marrow, and gastrointestinal tract cells, resulting in unwanted side effects. The need for targeted treatments based on the molecular changes of tumor cells arises from the indiscriminate destruction of normal cells, the toxicity of conventional chemotherapy, and the development of multidrug resistance.

The cancer diagnosis and treatment field are rapidly evolving, and there have been many exciting developments in recent years. While much work remains to be done, these advances offer hope for improving patient outcomes and ultimately finding a cure for this devastating disease.
