"Health" as long as man has been alive, you will get cancer

Why do people get cancer?

This is probably from "alive" to start talking about ......

As long as people live

The body's cells will stop division

One point two, two in four ......

The birth of new cells

Old cells die

Maintain a cycle

If the body as a society

That is the cell of society "people"

There are good people, there are bad guys

Once every cell division

They are likely to be born a bad person

It is this:

But do not worry too much

Low probability of the birth of cancer cells

But also is eyeing "immune cells"

If cancer cells are hooligans

That is, the police immune cells

Your body in good time

Stem cells will get down immune cancer

But when you are old

Immune cells will retire

Cancer cells will stage a comeback

Split into a small rogue

Organized and disciplined "triad"

then

Underworld will develop into cancer

Many people think

China is a country of high incidence of cancer

But in fact

China's incidence of cancer is not high

The world's top 70 or so

Real high incidence of cancer of the place

Are developed

Global cancer incidence ranking

▼

because of them

Live longer

Age is an important factor in the pathogenesis of cancer

Both men and women

After the 50-year-old cancer rates will rise sharply

In addition to age,

There are some people more susceptible to cancer

such as

Take smoking for

A cigarette can bring 78 kinds of carcinogens clear

Cause lung cell death

Lung cells continue to divide new cells to repair the lungs

More cell division

Increase the probability of the birth of cancer cells

Those carcinogens is fueled

So, smokers are more likely to get lung cancer

Cancer Why so tough?

Cancer itself is not strong

Many things can destroy it

The real difficulty is: distinguish cancer cells

Because they all are "disguised" master

The first treatment

Chemotherapy and radiotherapy

Both therapies

Can easily kill cancer cells

But the question is:

Cancer cells and normal cells looked like

Chemotherapy and radiotherapy can not distinguish between them

Often harming normal cells

Therefore, this treatment must be controlled dose

Otherwise, life was not guaranteed

do you know?

"Arsenic" is a kind of chemotherapy drugs ......

(Hint: do Freeze patient use, according to a doctor's prescription to be precise dose)

All chemotherapy drugs

As long as enough doses, they are able to kill poison

Targeted therapies

Precision attack cancer cells

Because the side effects of chemotherapy, radiotherapy

Scientists invented the minor side effects

"Targeted drugs"

The drug appeared

To improve the survival rate of cancer patients part

But cancer is not a vegetarian

They soon learned to disguise

Once cancer cells have resistance

Targeting the drug is also a bit weak

Only a better understanding of cancer

In order to create better-targeted drugs

Immunotherapy

The new weapon of mankind

People there is a way

Strengthen the immune cells

Just to the immune cells in a "probe glasses."

They can identify cancer cells disguise
