Explanation:

Identify the correct characteristics of cancer cells:

1. Cancer cells have impaired cell-cell communication, so "Can't communicate properly with other cells" is correct.
2. Normal cells anchor to tissue attachment points; cancer cells lose this anchorage dependence, so "Anchor to attachment points in tissues" is incorrect.
3. Cancer cells often secrete their own growth-promoting signals, so "Can secrete their own growth hormones" is correct.
4. Cancer cells do not perform normal specialized cell functions, so "Carry out normal cell functions" is incorrect.

Answer:

• Can't communicate properly with other cells.
• Can secrete their own growth hormones.
