The term that refers to the process of programmed cell death is apoptosis. Apoptosis is a crucial physiological process that allows the body to eliminate unhealthy or unnecessary cells without causing an inflammatory response. This process is essential for normal development and tissue homeostasis, as it helps to maintain a balance between cell proliferation and cell death.

During apoptosis, cells undergo a series of characteristic changes, such as cell shrinkage, chromatin condensation, and DNA fragmentation, ultimately leading to the orderly dismantling of cellular components. This safe and controlled form of cell death is vital for preventing the development of cancer, as it helps remove cells that may acquire mutations or become dysfunctional.

In contrast, angiogenesis refers to the formation of new blood vessels, which is an essential process for tumor growth and metastasis. Lymphoma is a type of cancer that originates in the lymphatic system, and invasion describes the ability of cancer cells to infiltrate surrounding tissues. None of these terms pertain to the mechanism of programmed cell death as apoptosis does.
