How do tumors become cancerous?

Question

I'm doing an extra credit assignment and it would be helpful if I got some answers. thanks

Answer 1

its an overproduction of cells which eventually necrose...mutations of the cells within the tumor can lead to cancer.

Answer 2

That's a query in your health practitioner! Pituitary tissue just isn't brain tissue despite the fact that the gland is on your mind. It may reason different problems due to the fact that it's a gland however now not most often melanoma. Find out extra from your doc precisely what variety of tumor it is and where it is in the gland. Take notes if it helps so you are very clear about it. He's purported to let you know all this. It's your body and your lifestyles. He works for you!

Answer 3

Cancer simply means that cells are growing and multiplying over the limit. They are out of control. The end result is a tumor which keeps getting bigger and bigger. What causes cancer remains a mystery, but we are all born with it and if allowed to live long enough would die from it. Most people wind up dying from something else. The only tumor that is not cancerous is a wart.

Answer 4

Inside our bodies are oncogenes. These control the cell multiplication and inhibits cellular growth within our bodies. They are programmed to stop growing if it contacts with another cells, or called as contact inhibition. If something goes wrong with them, cells starts to multiply out of control and can no longer be inhibited, that is when tumors become cancer. Usually the free radicals are the cause of their malfunction. We get these from the preservatives found in canned goods, and other synthetic products.

Answer 5

tumours are either malignant - cancer or benign - non cancerous. They do not become so, they develop that way, some do appear to be benign but are not, which is where people get confused. A cancer does not always have a tumour as such but can be spread quite thinly across an area, basically the cells continue to spread and in the case of cancer destroy the good cell by changing them into replica cancer cells or by absorbing them. In myaloma it is the overproduction of one cell and the destruction or prevention of red (or alternatively white) cells thereby.

Answer 6

A few types of cancer in non-humans have been found to be caused by the tumor cells themselves. This phenomenon is seen in Sticker's sarcoma, also known as canine transmissible venereal tumor.The closest known analogue to this in humans is individuals who have developed cancer from tumors hiding inside organ transplants.

Answer 7

tumors start out just a lump of harmless cells but too many can develop problems and deformities so it causes cancer .

Answer 8

Over activity, usually because of a deficiency in diet.
Caution: the drug industry controls what Doctors learn. Many think the only cure is by cutting. It's not. Nutrition can stop many problems.

Answer 9

They produce too many cells.
