Question

How do cancer cell differ from noncancerous cell? how are they similar ?

Answer 1

Answer:

Cancer cells differ from noncancerous cells in several ways. Here are a few examples:

1. Uncontrolled Growth: Cancer cells grow and divide uncontrollably, unlike normal cells, which have a regulated growth cycle.

2. Genetic Changes: Cancer cells have genetic changes or mutations that cause them to behave abnormally, which can lead to the formation of tumors.

3. Immortality: Cancer cells can divide indefinitely, unlike normal cells, which have a limited lifespan.
Invasion and Metastasis: Cancer cells have the ability to invade and metastasize to other parts of the body, while normal cells generally stay in one location.

However, cancer cells also share some similarities with normal cells. Both cancer cells and normal cells are made up of the same types of molecules, such as proteins, lipids, and nucleic acids. They also require nutrients and energy to survive and grow. Additionally, cancer cells can undergo many of the same processes as normal cells, such as DNA replication and cell division. However, these processes are dysregulated in cancer cells, leading to uncontrolled growth and other abnormalities.

Answer 2

1) grow in the absence of signals telling them to grow.

2)
Normal cells follow a typical cycle: They grow, divide and die. Cancer cells, on the other hand, don't follow this cycle. Instead of dying, they multiply and continue to reproduce other abnormal cells. These cells can invade body parts, such as the breast, liver, lungs and pancreas
