tumorinitiering
Tumorinitiering refers to the initial stage of cancer development where a normal cell undergoes a genetic alteration that marks the beginning of its transformation into a tumor cell. This process is often triggered by exposure to carcinogens, which are substances or agents that can cause cancer, or by spontaneous errors in DNA replication. These initial genetic changes, known as mutations, can affect genes that control cell growth, division, or repair.
Once a cell acquires these critical mutations, it may begin to divide uncontrollably, forming a small cluster
Further changes, often referred to as tumor promotion and progression, are necessary for the initiated cells
