Cancerous cells do not show

Options

A. Uncontrolled divisions
B. Metastasis
C. Contact inhibition
D. Neoplastic transformation

Answer

**Step-by-Step Solution:**

1. **Understanding Normal Cell Behavior**: Normal cells in the body have mechanisms that regulate their growth and division. They know when to divide and when to stop dividing based on signals from neighboring cells.

2. **Contact Inhibition**: One of the key properties of normal cells is contact inhibition. This means that when normal cells come into contact with each other, they receive signals that inhibit further division. This helps maintain proper tissue structure and function.

3. **Cancerous Cells**: Cancerous cells, also known as oncogenic cells, lose this ability to regulate their division. They do not respond to signals from neighboring cells and continue to divide uncontrollably.

4. **Uncontrolled Division**: The hallmark of cancerous cells is their uncontrolled division. Unlike normal cells, which stop dividing when they are in contact with other cells, cancerous cells ignore these signals and proliferate excessively.

5. **Conclusion**: Therefore, cancerous cells do not show the property of contact inhibition, which is a characteristic feature of normal cells.

**Final Answer**: Cancerous cells do not show contact inhibition.
