What causes cells to replicate and form tumours?
Cancer cells are able to hide themselves from the immune system so they’re not killed off
Response by Guest Expert Being Together Hertfordshire: Dr Rebecca Kristeleit

In our normal cells, there are many, many mechanisms to keep those cells healthy. Cancer cells are able to hide themselves from the immune system so they’re not killed off. Cancer cells are able to evade all those normal mechanisms that would normally detect a faulty cell. It’s helpful to think about these things in therapeutic targeting, and trying to target several of those mechanisms in order to prevent the cancers being able to grow. If we could understand fully how the cancers start, we could stop them growing.
