Question

How is a cancerous cell different from a normal cell?

Answer 1

Normal cells and cancerous cells are different from each other in the following ways:

• Cells have slow growth and cancerous cells have fast and uncontrolled growth.

• Contact inhibition is present in normal cells which means cells growth stops when cells come in contact with each other whereas in cancerous cells growth is uncontrolled and no contact inhibition is present.
• Metastasis is not present in normal cells whereas in cancerous cells metastasis is present meaning they can travel through the body and form a tumour at another location.

Answer 2

The key differences between normal cells and cancer cells are:-

1) *CELL SHAPE*

• Normal cells shape changes accordingly the specialized functions. All the normal cells possess a uniform shape.

• Cancer cells:- They possess irregular shape

2. *NUCLEUS*

•Normal cells- Spheroid shape, single nucleus

• Cancer cells:- irregular and multi-nucleated

3) *CHROMATIN*

•Normal cells- evenly distributed

•Cancer cells:- present in aggregated form

4) *GROWTH*

•Normal cells:-Controlled

•Cancer cells:- Uncontrolled

5) *MATURATION*

•Normal cells:- mature into specialized cells

•cancer cells:- remain immature

Explanation:

• __Our human body posses approx *37 trillion cells* ..

•The normal cells are the body *basics building blocks* and perform specific functions ..

•Some *genetic changes* disrupt the functioning of normal cells affecting their growth.

• Cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumour

•Cancer cells have more genetic changes as compared to normal cells

•The genetic changes further affect the specific types of genes

1) *Proto-oncogenes

2)DNA repair gene

3)Tumor suppressor gene*
