Microbiology Can single-celled bacteria get cancer?

Typically, growth of single-celled organisms is limited by nutrients and the time it takes for them to replicate their genome. Cancer grows uncontrollably, but cancer cell growth is also limited by the nutrients it can get from the environment. Thus, it can be argued that unicellular organisms are similar to cancer cells. However, for bacteria, rapid growth can be beneficial as it can make more copies of its genome (multiply). For the same reason, it is also an advantage for the cancer cell, but a big problem for the organism in which the cancer cell grows. Rapid growth absorbs nutrients and produces toxins that kill the host. So, in the end, bacteria cannot get cancer. But that's a semantic point. It all comes down to the definition and effect of cancer on the host.

No, this is only a trait of multicellular organisms
