Is blood cancer hereditary?

Have you ever found yourself questioning if blood cancer could be passed down by your parents? Or maybe you’ve had a loved one diagnosed with this disease and have wondered how much of it is due to genetics. Let’s dive into the nitty-gritty of it all, shall we?

What is Blood Cancer?

Before getting into whether or not blood cancer is hereditary, let’s first understand what it actually means. Blood cancer, also known as hematologic cancer, is a type of disease where abnormal cells form in the blood and bone marrow. This then causes problems like infections or bleeding since these cells cannot function properly.

The most common types of blood cancers include leukemia, lymphoma, and myeloma – which each differ in severity and location.

Oh yeah…and did I mention that there are different stages for each type as well? Warning: if you’re someone who likes simple answers to things…you might want to sit down for this one.

How Does Blood Cancer Develop?

Hold up – before we can answer more questions about heredity concerning blood cancer (don’t worry that’s coming soon) – it’s crucial to know how exactly these cancers develop in people so we can get an accurate gauge at how often it occurs through genes. So buckle up folks!

There are different factors that contribute to why a person could develop any type of hematologic cancer such as inherited traits from their ancestors (yep!), environmental exposures (darn air pollution), certain lifestyle choices(say goodbye cigarettes), etcetera etectera…

Ahh! It sounds way too complicated doesn’t it? But don’t worry; take a deep breath because here comes the low-down on all those confusing terms:

Inherited Traits

As human beings our genetic code determines many features including eye color: will they be brown/green/blue/alien-red?, height : how high can those heels go ladies? And other traits that are passed down by our parent(s). However if blood cancer is caused, at least partially, by genetics then how exactly does it work?

The truth of the matter is…well actually researchers aren’t even sure about the details fully – but what they have been able to identify are certain gene mutations which lead to an elevated risk for developing any type of hematologic disease. Gene mutation simply means that there has been a change/alteration in genetic material and as a result something could be done differently (think spider-man).

But hang on tight because things get more complicated than just one trait expression…

Environmental Exposures

Yes like I mentioned earlier; this plays a part too! When we talk about environmental factors let’s make it clear that these encompass anything occurring externally around us such as air pollution, water contamination with chemicals, etc. Things not within our control folla??

Some research shows how people exposed to higher levels of Benzene (which is found in tobacco smoke and gasoline) or radiation exposure had a greater likelihood of getting diagnosed with leukemia.

So why bring this up when talking about heredity you ask? Because JUST having inherited gene mutations won’t always guarantee development over time into an actual tumor.

Is Blood Cancer Hereditary?

You might’ve guessed from all the information above: yes sometimes – BUT mostly no. Let me elaborate:

Genetic Factors

As far back as early history goes-certain diseases have long been known to “run” in particular families . Maybe your grandfather smoked three packs a day and everything was fine- until he wasn’t anymore-and then his son/brother/cousin was also diagnosed with lung cancer!

When considering blood cancer specifically scientists now believe from their studies sometime approximately only 5% cases happen primarily due being hereditary. Sometimes multiple family members across generations can be affected during a lifetime leading to suspicion of this.

However as much as the term hereditary can act like an ‘all-sounder’, it still does not have an isolated significance behind leading some lines or families into developing hematological disorders. Fact time: With more research being done, mutations alone however seem to raise the risk only slightly!

Chance

It may sound strange but there is actually such thing as random genetic mutation (yes really!) Not everything we develop is from our genes being inherited. Blood cancer is more often than not a random event and occurs spontaneously in most people without any history within their lineage, serving up that notorious surprise-factor.

Now hold your horses! I’m sure you’re thinking what about familial prevalence and cases with siblings who meet parallel fates- It isn’t unusual for different family members to deal with many issues throughout life regarding health patterns so similarities between bother/sister could totally be coincidental at best.

So What Does This Mean For You?

Bottom line folks? Genetics are definitely considered one part of blood cancer development; however environmental factors and simple chance also play important roles. Overall, if you do feel unsure or nervous about risks then just don’t hesitate reaching out to your doctor whether genetic counseling would be necessary/helpful – they’re always glad taking initiative when it comes down assessing potential concerns preemptively.
