Cancer Cells vs. Normal Cells: What’s the Difference?

There are many differences between cancer cells and normal cells. Some of the differences are well known, whereas others have only been recently discovered and are less well understood. You may be interested in how cancer cells are different as you are coping with your own cancer or that of a loved one. For researchers, understanding how cancer cells function differently from normal cells lays the foundation for developing treatments designed to rid the body of cancer cells without damaging normal cells. The first portion of this list discusses the basic differences between cancer cells and healthy cells.

Essentially, cancer is a disease of mitosis. As such, it occurs when normal cells are transformed into cancerous cells and proliferate uncontrollably. In the process, some of the cancer cells end up forming tumors not only at the first region to be affected lungs etc but also result in secondary malignant growths away from the primary site known as metastasis. Some of the main characteristics of cancer cells that differentiate them from other normal cells include:. Before looking at some of the main characteristics of cancer cells in detail, it's worth understanding what causes cancer. Basically, the transformation of a cell from normal to cancerous is caused by agents that are collectively known as carcinogens. On the other hand, such biological factors as viruses e.

Although most individuals facing a cancer diagnosis want to know what caused their cancer, the answer is not that simple. Living organisms, including human beings, are made up of cells. Cells generally have a specific life cycle depending on their location in the body. Different cells have different lifespans. For instance, your liver cells may live from six months to a year before being replaced.

Cancer cell

Cancer affects 1 in 3 people in the United States. Chances are that you or someone you know has been affected by cancer. Here is some information to help you better understand what cancer is. You are made up of trillions of cells that over your lifetime normally grow and divide as needed. When cells are abnormal or get old, they usually die. Cancer starts when something goes wrong in this process and your cells keep making new cells and the old or abnormal ones don't die when they should. This makes it hard for your body to work the way it should.

Cancer cells are cells that divide relentlessly, forming solid tumors or flooding the blood with abnormal cells. Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because of aging or damage. Healthy cells stop dividing when there is no longer a need for more daughter cells, but cancer cells continue to produce copies. They are also able to spread from one part of the body to another in a process known as metastasis. There are different categories of cancer cell, defined according to the cell type from which they originate.

Porse; Comparing cancer vs normal gene expression profiles identifies new disease entities and common transcriptional programs in AML patients. Blood ; 6 : — This study describes a method for the comparison of gene expression data of any type of cancer cells with their corresponding normal cells. Our analyses reveal novel disease entities, identify common deregulated transcriptional networks, and predict survival. Gene expression profiling has been used extensively to characterize cancer, identify novel subtypes, and improve patient stratification. However, it has largely failed to identify transcriptional programs that differ between cancer and corresponding normal cells and has not been efficient in identifying expression changes fundamental to disease etiology. Here we present a method that facilitates the comparison of any cancer sample to its nearest normal cellular counterpart, using acute myeloid leukemia AML as a model.

What Is Cancer?

Прикрыв глаза, давая им долгожданный отдых, он вдруг почувствовал, что кто-то тянет его за ногу.

Коммандер поднес его к уху. - В чем дело? - рявкнул он и замолчал, внимательно слушая собеседника. Сьюзан на какое-то время забыла про Хейла.

Мы должны пойти на. - Слишком поздно, - сказал Стратмор. Он глубоко вздохнул.

Сьюзан завороженно смотрела на захватывающую дух технику. Она смутно помнила, что для создания этого центра из земли пришлось извлечь 250 метрических тонн породы. Командный центр главного банка данных располагался на глубине шестидесяти с лишним метров от земной поверхности, что обеспечивало его неуязвимость даже в случае падения вакуумной или водородной бомбы. На высокой рабочей платформе-подиуме в центре комнаты возвышался Джабба, как король, отдающий распоряжения своим подданным. На экране за его спиной светилось сообщение, уже хорошо знакомое Сьюзан. Текст, набранный крупным шрифтом, точно на афише, зловеще взывал прямо над его головой: ТЕПЕРЬ ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА ВВЕДИТЕ КЛЮЧ_____ Словно в кошмарном сне Сьюзан шла вслед за Фонтейном к подиуму.

 - Дело в том, что это и есть ключ. Энсей Танкадо дразнит нас, заставляя искать ключ в считанные минуты. И при этом подбрасывает подсказки, которые нелегко распознать. - Абсурд! - отрезал Джабба.
