Summary Introduction

To write:

To discuss the differences between the normal and cancerous cells.

Introduction:

Cancer cells are found as very different from the normal cells in terms of size, shape, and organization. These cells are known as abnormal cells because they have abnormal features of the division.

Explanation of Solution

Some of the common differences between the cancerous cells and normal cells are the following:

Normal cells stop growing (reproducing) when enough cells are present bu cancerous cells keep on dividing. Cancer cells don't communicate with other cells as normal cells do. Normal cells keep on communicating with nearby cells.

Normal cells get when they are damaged or get old. Cancer cells are not repaired or do not undergo apoptosis. Normal cells secrete substances that make them stick together in a group. Cancer cells do not stick together. Normal cells perform the specialized function, whereas cancer cells may not be functional. Normal cells stay in a specific area, For example, lung cells remain in the lungs.

Cancer cells, due to lack of adhesion molecules that cause stickiness, are able to travel via the bloodstream and lymphatic system to other regions of the body. They have the ability to metastasize. Normal cells reproduce themselves and then stop when enough cells are present. Cancer cells reproduce rapidly before the cells have had a chance to mature. Normal cells mature. Cancer cells, because they grow rapidly and divide before cells are fully mature, remain immature.

Conclusion

Thus, there is a number of differences found between the cancerous cells and normal cells.
