When cells are not responding to normal controls over growth and division they form tissue mass known as?
When cells are not responding to normal controls over growth and division, they can form tissue masses known as tumors. Tumors can be either benign (not cancerous) or malignant (cancerous).
When uncontrolled cell division occurs cells can become what?
When uncontrolled cell division occurs, cells can become cancerous. Cancerous cells can continue to divide and grow uncontrollably, forming a tumor. These cells can also invade surrounding tissues and spread to other parts of the body through a process called metastasis.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
Why are the number of cells in division higher for cancerous cells?
Cancerous cells divide more rapidly than normal cells due to mutations that disrupt the regulatory mechanisms controlling the cell cycle. These mutations can lead to the overexpression of growth factors, activation of oncogenes, or inactivation of tumor suppressor genes, all of which promote uncontrolled cell proliferation. Additionally, cancer cells often evade the normal apoptotic signals that would typically lead to cell death, allowing them to accumulate in greater numbers. As a result, the overall rate of cell division in cancerous tissues is significantly higher.
Would cancerous cells be more dangerous if they went through mitosis slower than normal cells?
Cancerous cells are typically characterized by uncontrolled and rapid cell division, which allows them to proliferate quickly and invade surrounding tissues. If cancerous cells underwent mitosis more slowly than normal cells, they might be less aggressive in terms of growth and spread. However, their danger could still stem from other factors, such as their ability to evade the immune system or resist treatments. Ultimately, the overall impact of cancerous cells depends on multiple factors beyond just the rate of mitosis.
What is a uncontrolled division of cells?
A cancerous tumor.

Why the cells depicted in line A are most likely cancerous?
The cells in line A are likely cancerous because they appear crowded, irregularly shaped, have enlarged nuclei, and are not organized in a uniform manner as normal cells. These characteristics suggest uncontrolled growth and division typical of cancerous cells.
Will normal or cancerous cells have a higher growth rate?
the cancerous cells
What kind of cell don't respond to normally to the bodys control system for cell division and divide excessively?
Cancerous cells.
What is happening to the cells in the field and why?
The cells in the field are experiencing a high rate of division known as mitosis. This rapid cell division is necessary for growth and repair within the field. As the cells continually divide, they differentiate into specific cell types to carry out various functions in the body.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
How many cells are in prophase during the process of cell division?
During prophase of cell division, there are typically 46 cells in humans.
What role does mitosis play in cancer?
Mitosis arguably plays the largest role in cancer. Mitosis is responsible for the growth and division of the cancerous cells.
What cells are more cancerous?
Brain cells
