Die neuen Impfstoffe und Behandlungen, die den Krebs in den Strecken stoppen könnten

[Cancer](https://inews.co.uk/topic/cancer?ico=in-line_link), one of the most feared of all medical conditions, is often seen as an unstoppable force. But in fact, the opposite is true. It is common for our bodies to successfully eradicate early cancers without us even noticing.

By middle age, most of us probably have several microscopic tumours dotted around the body that are in the process of being destroyed by the immune system. It is only when cancers start beating our immune defences that they grow to a noticeable size and cause symptoms.

Once a tumour has reached this stage, while the [immune system](https://inews.co.uk/news/health/the-truth-about-boosting-your-immune-system-fighting-viruses-819001?ico=in-line_link) battle continues, the cancer is much more likely to win. Yet many scientists believe the fact that the immune system can defeat at least some early cancers suggests it could hold the secret to developing better treatments.
