What are the differences between normal cells and cancer cells in terms of their characteristics and behavior?
Normal cells and cancer cells differ in several ways. Normal cells have a controlled growth and division rate, while cancer cells grow uncontrollably. Normal cells have a specific function in the body, while cancer cells lose their specialized function. Additionally, normal cells undergo programmed cell death when necessary, but cancer cells evade this process. Finally, normal cells have a limited ability to spread to other parts of the body, while cancer cells can invade nearby tissues and metastasize to distant organs.
What is the process through which cells normally die How are cancer cells different?
Cells normally die through a regulated process called apoptosis, or programmed cell death, where they undergo a series of biochemical events leading to cell shrinkage, DNA fragmentation, and ultimately elimination by immune cells. This process is crucial for maintaining tissue homeostasis and removing damaged or unnecessary cells. In contrast, cancer cells often evade apoptosis, allowing them to survive and proliferate uncontrollably due to mutations that disrupt the apoptotic pathways. This resistance to cell death contributes to tumor growth and the persistence of cancerous cells in the body.
How is the behaviour of cancer cells different from that normal cells?
Cancer cells have the ability to grow and divide uncontrollably, whereas normal cells grow and divide in a regulated manner. Cancer cells can also invade surrounding tissues and spread to other parts of the body, a process known as metastasis, which normal cells do not do. Additionally, cancer cells may evade the body's immune system and resist cell death signals that would normally eliminate damaged cells.
What happens when cells do not respond the signals that normally regulate their growth?
Cancer cells do not respond to the signals that regulate the growth of most cells. such cells called cancer cells divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues
what is a breast cancer?
Brest cancer is any unregulated growth in breast tissue. Cells in tissues normally have "boundaries" that they do not go beyond. Cancer cells don't pay any attention and grown beyond and over these.
What cell function appears to go awry in the case of cancer cells?
Cell reproduction goes awry in the case of cancer cells. Due to an error in DNA replication, the normal mechanism that controls cell reproduction does not function, and the cancer cells continuously reproduce without any control.
What happens when cell do not respond to the signals that normally regulate their growth?
Cancer cells do not respond to the signals that regulate the growth of most cells. such cells called cancer cells divide uncontrollably and form masses of cells called tumors that can damage the surrounding tissues
A scientist has decided to develop a new cancer treatment she has observed how patients react to current treatments function when they encounter cancer cells and how cancer cells behave in the body wh?
Make a plan of what approach she will take to treat cancer.
What is one difference between cancer cells and normal cells?
One key difference is that cancer cells can divide uncontrollably whereas normal cells have a regulated cell division process. This uncontrolled division is one of the factors that leads to tumor formation in cancer cells.
Is cancer made of atoms or elements?
Cancer is made of atoms, which are the basic building blocks of all matter, including elements. The atoms in cancer cells interact to form molecules, which make up the structure and function of cells.
Why is it important to know how cells divide when studying cancer?
I am no expert, but I remember very clearly his section of my biology class. Basically, cells go through a few phases when they divide. Once a cell has officially replicated itself, it goes through a checking process to make sure that the new cell has the proper genetic make up and that no mistakes were made in the replication process. In cancer cells, this process is skipped. The "healthy" cells make "unhealthy" cancer cells, but don't realize it. The healthy cell then dies off because there is a cell to replace it. However, the cell taking its place is a cancer cell. The cancer cell then divides and makes more cancer cells. This is how cancer grows and replaces healthy tissue. Also, because the cells don't take the time to make sure the cell was replicated properly in the cancer process, the cancer cells grow faster because they don't stop to double check that their growth is proper.
What are the cancer cells called that break free and travel?
Cancer cells that break free and travel to other parts of the body through the bloodstream or lymphatic system are called metastatic cancer cells.
