What stops the body from telling cancer cells for apoptosis?

One of the defining characteristics of cancer cells is that they systematically prevent programmed cell death (apoptosis), with which the body guards itself against the proliferation of defective cells. In order to do this, they express so-called apoptosis inhibitors (IAPs) among other proteins.

What is cancer cell apoptosis?

Cell biologist Michael Overholtzer explains apoptosis, a form of programmed cell death that can lead to cancer when it doesn’t function properly. The death of one tiny cell might seem like a simple thing. But the process is much more complicated than you would expect.

Does apoptosis occur in cancer cells?

Cancer is one of the scenarios where too little apoptosis occurs, resulting in malignant cells that will not die. The mechanism of apoptosis is complex and involves many pathways.

How do cancer cells survive?

Cancer cells have the same needs as normal cells. They need a blood supply to bring oxygen and nutrients to grow and survive. When a tumour is very small, it can easily grow, and it gets oxygen and nutrients from nearby blood vessels.
