Читать книгу The Cancer Directory - Dr. Daniel Rosy - Страница 84

A normal cell knows where it should be, and stays there until it dies, when another cell takes its place. It does this by sticking to the cells surrounding it. A cancer cell loses this ‘stickiness’ and breaks away from its surroundings to be transported via various body systems to other organs, where it takes up residence and starts to divide and grow into a new tumour. This is known as ‘metastatic spread’, or the development of a secondary cancer.
