Cancer Biology and Cell Science

Track 1 : Cancer

Cancer is a broad term. It describes the disease that results when cellular changes cause the uncontrolled growth and division of cells.

Some sorts of cancer cause rapid cell growth, while others cause cells to grow and divide at a slower rate. Certain sorts of cancer end in visible growths called tumors

Most of the body’s cells have specific functions and glued lifespans. A cell death is part of a natural and beneficial phenomenon called apoptosis.

A cell receives instructions to die in order that the body can replace it with a modern cell that functions better. Cancerous cells lack the components that instruct them to stop dividing and to die.

As a result, they build up within the body, using oxygen and nutrients that might usually nourish other cells. Cancerous cells can form tumors, impair the system and cause other changes that prevent the body from functioning regularly.

Cancerous cells may appear in one area, then spread via the lymph nodes. These are clusters of immune cells located throughout the body.

Causes:

There are many causes of cancer, and some are preventable

For example, over 480,000 people die in the U.S. each year from smoking cigarettes, according to data reported in 2014.

In addition to smoking, risk factors for cancer include:

• heavy alcohol consumptionexcess weight physical inactivity
• physical inactivity
• poor nutrition
