What are dividing normal human cells called?
Healthy, non-cancerous cells.
Why is it harmful for cells to become too large?
Cells that become too large can either block nutrients to other cells, or become a cancerous cell.
Is the percentage of cells in the resting stage is higher in cancerous cells than normal cells?
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
If cancer is present what is the likely explanation for what happened to cells B and D?
The choices are -they were harmed by radiation therapy -they died off because the cancerous cells deprived them of nutrients -they died off due to natural causes - they thrived with the cancerous cells
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 %
Will normal or cancerous cells have a higher growth rate?
the cancerous cells
Can radiation cure certain disease?
Radiation can cure cancer through what is known as radiation therapy. This is a process where the cancerous cells and genes are damaged.
What is a mutation that forms an oncogene that changes normal cells into cancerous cells?
to a gene
What are dividing normal human cells called?
Healthy, non-cancerous cells.
Why are sunbeds unhealthy?
It is like standing next to a star. Sunbeds expose you to ultraviolet radiation and this can ionise your cells and damage them as it passes through your body. This is potentially harmful if too many cells get damaged as they can become cancerous and cause a tumour which can kill you.
What is it called when normal body cells turn cancerous?
Carcino-Genesis.
How does Radiology treat cancer cells?
Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. ... But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells.
Is the percentage of cells in the resting stage is higher in cancerous cells than normal cells?
No, cancer cells are more active than normal cells. Cancer cells are always dividing at a faster rate than normal cells.
Why is it harmful for cells to become too large?
Cells that become too large can either block nutrients to other cells, or become a cancerous cell.

Can radiation kill pancreatic cancer?
When ionising radiation interacts with living cells is usually kills these cells. Thus yes, radiation can kill pancreatic cells that are cancerous. However the radiation will also destroy healthy cells (and destroy the pancreas) so the amount of radiation given has to be low and well targeted. This is difficult to achieve and if any cancerous cells remain alive they will regrow the cancer.
What are radioactive implants?
Radioactive implants are devices that are placed directly within cancerous tissue or tumors, in order to deliver radiation therapy intended to kill cancerous cells.
