And why it is so difficult to treat
- Cancer cells vary in size and form. They grow in a very chaotic way.
- Cancer cells don’t stop dividing.
- They destroy surrounding healthy cells by invasion.
Our immune cells don’t detect cancer cells easily, and fail to recognise the danger.
They spread to other body parts, including important organs, at the very beginning.
Affected cells lose the ability to stop dividing.
Areas inside tumours with a bad blood circulation can’t be reached by many drugs
There are always cells within a tumour that are resistant to the treatments
In many cases, the immune system is already weak due to lifestyle factors
