Adverbs of degree

It seems like you're always hearing about how just about everything gives you cancer.

Adverbs of manner

It's always something you constantly come in contact with.

Modal verbs - B1

Then there might be some article saying the opposite.

Cancer is really tricky, and there are still so many studies to be done.

But there are some things that the scientific community is fairly confident about when it comes to cancer rates.

Let's arm ourselves with knowledge and leg ourselves with smarts.

Trillions of cells in your body, each housing around 20,000 genes within its DNA.

These genes are the masterminds behind controlling cell functions.

But when mutations strike, resulting in wacky proteins and chaos ensues, cancer may emerge, turning cells into uncontrollable replicating machines.

And this sounds like an action movie, but alas, it's real life.

But wait, what triggers these gene mutations, you ask?

The family heirlooms passed down from your parents.

Quite rare, accounting for only 5 to 10% of cancer cases, which the real party crashers are acquired or somatic mutations.

These sneaky mutations can occur during DNA replication, adding an element of randomness into the mix.

Studies suggest they can contribute to 10 to 30% of cancer cases.

Now, let's unveil the culprits behind these genetic shenanigans, shall we?

Your cells face all sorts of damage throughout life's grand adventure.

Think UV radiation, tobacco viruses, diet, inflammation, and even good old aging.

It's like a cosmic game of whack mutation.

Keep in mind cancer is a multi step process.

We're talking about several mutations before it takes center stage.

That's why it often prefers a mature audience.

Older folks who have had more time for these genetic slip ups to accumulate.

While you can't exactly choose your genes or halt the clock.

There's hope in avoiding cancer's more aggressive party invitations.

As cigarette sales boomed, lung cancer mortality rates skyrocketed.

Studies even found that 87% of lung cancer deaths were caused by tobacco use.

So when cigarette sales decreased, so did the number of lung cancer deaths.

This could be accomplished with other types of cancer as well.

For example, about 90% of non melanoma skin cancer cases are caused by exposure to the sun's.

UV radiation, which can be avoided by staying out of the sun or wearing protective clothing or sunscreen.

And over 95% of cervical cancer cases are caused by the human papilloma virus, which there are vaccines for.

All these might sound scary, but these preventative measures can start right now.

While risk can never be eradicated completely, we can minimize it by living healthy lives.

There are a lot of really smart people figuring out how to stop you.
