Radiation can harm both normal and cancerous cells, but because cancerous cells are often more sensitive to radiation, they may be more likely to be damaged or killed by radiation therapy. Normal cells can repair themselves more effectively than cancerous cells, which helps protect them from the effects of radiation.

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.
What are cells that are not cancerous and have no affect on health called?
Non-cancerous cells that do not affect health are referred to as normal cells. These cells function properly within the body and perform their intended roles without causing harm or disrupting the normal functioning of tissues and organs.
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).
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 %
What are dividing normal human cells called?
Dividing normal human cells are called somatic cells. These cells undergo the process of mitosis to divide and create identical daughter cells with the same genetic material.
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
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.
What are cells that are not cancerous and have no affect on health called?
Non-cancerous cells that do not affect health are referred to as normal cells. These cells function properly within the body and perform their intended roles without causing harm or disrupting the normal functioning of tissues and organs.
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.
What is Radiation used in a sentence?
Radiation therapy is commonly used to treat cancer by targeting and destroying cancerous cells with high-energy radiation beams.
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 does nuclear waste do to you?
The nuclear waste gives off radiation. That radiation in large enough doses changes DNA in cells. When the DNA changes sometimes the cells can become cancerous. In even higher doses the cells will die.
