Why do people get cancer??

Question

how come certain people get cancer and some people dont?

Answer 1

It can be hereditary.

Other times it can be from UV lighting, sun, smoking, cellphones, or just not looking after your body.

Answer 2

Some people get cancer because of their genes.

Or smoking.

Answer 3

two reasons

1. exposure to outside sources (the list is really long, but foods, chemicals, airborn toxins, etc.

2. a predisposition to cancer (inherting certain genes that make you more susecptible to cancer)

example: Christina Applegates cancer-her mother had breast cancer--she got it

also, both can occur--a person with a predisposition to cancer is a heavy smoker

Answer 4

it has to do with the make up of their cells. genes have a lot to do with it.

Answer 5

Cancer is when a normal cell mutates and does not function normally anymore. It then replicates itself over and over sometimes causing tumors. Your body can usually get rid of these cells but not always. Cancer can be caused by so many things these days. Such as the sun, certain chemicals in the body, possibly cell phones, and so on.

Answer 6

Many reasons.

It is not a totally random disease.

Taking care of yourself plays a huge part in it. For example simply getting enough vitamin d throughout your life can cut your risks by around 60%.  http://www.forbes.com/health/feeds/hscou...

Other things such as anti-oxidants and exercise reduce cancer risks too. This is because it it harder for cancer to grow in a well oxygenated environment and because antioxidants kill free radicals that help contribute to cancer growth. I have links to those, but I don't know where they are right now. Google searches for those search terms will give you some info on that.

Exposure to toxins in the air, water, and products people use contribute, too. Avoiding these things and using things like water filters helps, too. I've found after many years that for almost every toxic thing to get the job done, even things like shampoo and bleach, there is a safer, cancer-free alternative that usually costs much cheaper.

There is more, but commit yourself to a healthy lifestyle and you will most likely avoid it. A healthy life style is something that you really need to read into to know much about because there are many people out there giving advice, and not all of it is good. Go for the stuff that has some backing by clinical tests and such.

Most importantly, get enough vitamin d in your life. It makes your immune system strong and prevents cancer and does so many things.  Best bet is from the sun, but don't burn, that is when the risk for skin cancer starts to come. I get out for 30 minutes a day about 3 days a week. In the winter I take about 2,000 IU a day.

Answer 7

sometimes someones cell mutates randomly and causes cancer or if they have been exposed to small amounts of gamma radiation that can also cause cells to mutate

Answer 8

Nobody knows the answer to that question.

Nobody knows why some people get it and others, with the same lifestyle and  the same risk factors or lack of them, don't get it.

That's what's so frightening about cancer; we don't know what causes most cancers. Cancer affects the healthy and the unhealthy alike.

Some people may tell you it's down to avoidable lifestyle factors like bad diet; that's just a reflection of their fears and prejudices - it can be a lot less scary for some people who haven't had cancer to 'blame the victim' rather than accept that cancer is a largely random disease that can strike any of us at any time.

People may also tell you it's largely genetic; it isn't. Cancer that 'runs in families' is rare - fewer than 10% of all cancer cases are due to hereditary factors.
