Excessive angiogenesis and reduced apoptosis are two of the six characteristics that define cancerous tumors. Discuss how developing treatments for these two conditions might prevent the development of cancer altogether from pre-malignant tumors.

Angiogenesis:
Angiogenesis refers to the process of the growth and development of new blood vessels from existing blood vessels. This process is essential for the normal development and maintenance of the body's tissues and organs, as well as for wound healing and tissue repair. Angiogenesis is regulated by a complex interplay of signaling molecules and cells, including growth factors, extracellular matrix proteins, endothelial cells, and pericytes. Abnormal angiogenesis has been linked to a number of diseases, including cancer, cardiovascular disease, and diabetic retinopathy. Therefore, understanding the mechanisms of angiogenesis has important implications for the development of new treatments for these conditions.
Apoptosis:
Apoptosis, also known as programmed cell death, is a natural process that occurs in cells to ensure proper development and maintenance of the body. It is a tightly regulated process that eliminates unwanted or damaged cells without causing inflammation or harm to surrounding tissues. Apoptosis is characterized by a series of molecular events, including activation of caspases, DNA fragmentation, and membrane blebbing, which ultimately lead to the breakdown of the cell into small, membrane-bound apoptotic bodies that can be phagocytosed by neighboring cells or macrophages. This process plays a crucial role in a variety of physiological processes, such as embryonic development, tissue homeostasis, and immune system regulation. Dysregulation of apoptosis has been implicated in a number of diseases, including cancer, autoimmune disorders, and neurodegenerative diseases.
