Is cancer a virus or bacteria?

Please only answer if you honestly know and have something to back your answer up with.

Is cancer a virus or bacteria?
It is neither.

Cancer is simply a group of cells whose signals got turned on to keep multiplying.

There is some evidence that things like viruses and bacteria can CAUSE cancer... but they are not in and of themselves cancer.
Reply:neither it is a disease
Reply:Neither. It is an error in the replication of your DNA that causes cells to reproduce much faster than normal.
Reply:Cancer is neither a virus or bacteria. Cancer is an abnormality in the cell's genetic makeup that causes it to mutate. This mutation can be caused by toxins, radiation, genetics, etc... The mutation causes an abnormal growth called a tumor, or if smaller a lesion.
Reply:neither its uncontrolled growth of your own cells they grow and multiply but they don't kill them selves with apoptosis

it's because of mutations in your cells that make them lose their ability to perform apoptosis
Reply:Neither! Its when the DNA of a cell gets mutated causing it to divide uncontrollably. It produces lots of cells, all these cells together are called a tumour. I think this is right - i study biology at A-Level so i hope so!

Hope it helps.
Reply:cancer isn't a virus or bacteria, it's an uncontrolled growth of abnormal cells resulting in tumor, much more complex than a simple virus or bacteria.
Reply:Cancer is not a virus. There are some viruses that increase a person's risk of getting cancer, but cancer itself is not viral and not contagious. Cancer is not bacterial either, although certain bacteria are thought to facilitate cancer. It is a group of diseases characterized by uncontrolled growth and spread of abnormal cells resulting from an error in the way your DNA replicates.
Reply:Cancer can be caused by a virus or bacteria, but it is not a microorganism by itself. It is actually a deranged cell that has stopped reproducing normally. A cancer cell is characterized by rapid cell division, interference with neighboring cell function or sometimes producing toxic proteins.

One known viral contributor is the human paploma virus (HPV) that contributes to cervical cancer. But other things can cause cancers such as chemicals, pollutants, high electromagnetic fields and radiation.
Reply:its neither...

cancer is just a group of cells that have mutated inside a body and grow at a proliferated rate.

cancer is not an infection that could be caused by a bacteria or virus. cancer is classified as a non-transferable disease. non-transferable diseases cannot betransfered from one person to another. this kind of diseases also include diabetes, heart disease etc.

any disease that is caused by a microorganism is trasferable as the microorganisms can spread to other people by several mean such as air, water, bodily fliuds, etc.

such diseases include cold, malaria, pnemonia, etc.
Reply:If you are young and develop certain cancers, the Oncologist orders an HIV test.

I believe this is because cancers are immune mediated in our body. The Oncologist says we all have cancer in our body, but our immune system keeps it away. When our immunity fails, cancer comes into the picture.

Over the last 13 yrs, I have noticed AIDs pts are dying from Lymphoma which is cancer.

I believe we have not even begun to determine how cancers invade the human body, but it should be interesting to see what the next 50 yrs brings.
Reply:Cancer is part of your body wherease bacteria and viruses come from outside and are not part of your body.
