what are the basic elements causing cancer?

Question

i mean that if they basic cells are oncogens how do they enter the body? how did it enter the first person? and what are the types of cancer that can be cured?

Answer 1

Cancer is a class of diseases or disorders characterized by uncontrolled division of cells and the ability of these cells to invade other tissues, either by direct growth into adjacent tissue through invasion or by implantation into distant sites by metastasis. Metastasis is defined as the stage in which cancer cells are transported through the bloodstream or lymphatic system. Cancer may affect people at all ages, but risk increases with age. It is one of the leading causes of death in developed countries.

There are many types of cancer. Severity of symptoms depends on the site and character of the malignancy and whether there is metastasis. A definitive diagnosis usually requires the histologic examination of tissue by a pathologist. This tissue is obtained by biopsy or surgery. Most cancers can be treated and some cured, depending on the specific type, location, and stage. Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy. As research develops, treatments are becoming more specific for the type of cancer pathology. Drugs that target specific cancers already exist for several cancers. If untreated, cancers may eventually cause illness and death, though this is not always the case.

Answer 2

Melanoma cells are mutant cells that expand for the period of the body ,they do not ENTER the body simply is not recognized accurately what makes an extended-headquartered telephone to grew to become an cancerous telephone=changes that make this cells to divide out of control and in view that the frame produce them ,the body might no longer battle them ,so that they a few and take the complete blood circulate from the typical organs and enhance until they strangle the typical cells there are a few leukemia's they are saying curred in younger humans

Answer 3

Melanoma cells are mutant cells that improve for the duration of the physique ,they do not ENTER the physique simply isn't identified exactly what makes an extended-headquartered cell to grew to be an cancerous cell=adjustments that make this cells to divide uncontrolled and in view that the body produce them ,the physique would now not fight them ,in order that they a few and take the whole blood circulation from the normal organs and boost until they strangle the natural cells there are some leukemia's they're saying curred in younger persons

Answer 4

cancer cells are mutant cells that grow inside the body ,they don't ENTER the body
is not known exactly what makes a normal cell to became an cancerous cell=changes that make this cells to divide uncontrolled and because the body produce them ,the body doesn't fight them ,so they multiple and take all the blood circulation from the normal organs and grow until they strangle the normal cells
there are some leukemia's they say curred in young people

Answer 5

I can only say that all cancers originate from an aberration in the genetic structure of the cell and there are many ways of producing an altered genetic structure.

A simple virus could cause it, and many other catalists cause the alteration. Viruses alter genetic structure and permenantly alter the genes.

Answer 6

depends on the cancer. some it's radiation, or genetic. it's probably a mutation. most can be treated if not cured, but the earlier it's caught the better the chances of the patient are.
