Question

5. (5 pts.) Cells normally don't move from one tissue to another. But in late stages of cancer, cells move from one tissue to another. Using what you know about cell connections, explain what would have to happen for cancer cells to move to new tissue.

Answer 1

Mutations result in the formation of cancerous cells. Cancerous cells replicate in uncontrolable manner. Human system can't control their proliferation and death using cell signals. That is cancerous cell become irresponsible against cell signals.

During the initial stages of cancer , the cancer is appeared as benign. Benign tumours are those confined with in boundaries of tissue. Later stage of cancer, it is developed into malignant tumour. Malignant stage have the capability of breaking boundary and enter the nearby tissues. This terminal stage is knows as metastasis.

In metastasis, cancerous cell enters the blood stream , lymphatic system and thereby travels into new area of body. In those new area, they begin to divide and lay a basement for secondary tumours.
