Cancer: 4 Myths You Need to Know

Cancer: 4 Myths You Need to Know

With all the medical advances and education for cancer, it is amazing that myths and misconceptions about cancer still abound and worry us needlessly.Myth vs Fact graphic

Here we debunk a few common misunderstandings around cancer. Share this information with people as you gather this holiday season.  It could ease others’ cancer fears.

CANCER MYTHS

Number one

Cancer is always fatal.

Fortunately, this is incorrect. According to the National Cancer Institute Office of Cancer Survivorship, as of January 2022, it is estimated that there are 18.1 million cancer survivors in the United States. This represents approximately 5.4% of the population. The number of cancer survivors is projected to increase by 24.4%, to 22.5 million, by 2032.

Advances in the prevention, screening and treatment of cancer are improving cancer survivorship tremendously. 

number 2

Cancer is contagious.

Generally speaking, no, cancer cannot be “caught” from another person. It is also true that certain cancer-causing viruses and bacteria passed from one person to another can increase the likelihood of developing cancer. In rare circumstances involving transplantation or pregnancy, transmission has been known to occur.

Number 3

Cancer runs in families.

While some of us are born with genes passed down from our parents that may predispose us to developing cancer at some point in our lives, only about 5-10% of cancers are due to mutations inherited from a parent. Most cancers are caused by genetic changes that occur and build up from lifestyle choices and/or exposure to chemicals and environmental factors during our lifetime.

Number 4

Everything around us causes cancer.

Who hasn’t heard that using deodorant, cosmetics, hair dyes, smart phones, microwaves, sugar, artificial sweeteners, or being in close proximity to power lines all can cause cancer?

The good news: there is no consistent, conclusive scientific evidence to support these claims.

When you hear new or suspicious information about cancer, it’s a good idea to fact check by discussing it with your doctor. If you prefer to do your own online research, visit reliable cancer organization websites like these to find credible information you can trust. And, of course, there is a wealth of information on Bag It Cancer’s Resource Center.

But Cancer Doesn’t Run in My Family! What you should know about genetic testing

But Cancer Doesn’t Run in My Family! What you should know about genetic testing

 

Many people are shocked by their cancer diagnosis when no one in their family has been diagnosed with cancer. Cancer is caused by genetic changes (mutations or variants) in a person’s genes, chromosomes, or proteins, but that doesn’t generally mean it’s inherited from a parent. In fact, only about 5-10% of cancers are due to inherited cancer syndrome (germline mutation).

Whether you personally have cancer or not, genetic testing can be helpful for your situation. If you have a cancer that was caused by a mutation, genetic testing can provide important information about how to treat your cancer, as well as your risk for developing a second cancer. 

If you have not been diagnosed with cancer, genetic testing can estimate the likelihood of being diagnosed with certain types of cancer in your lifetime. The test can tell you if you have a higher risk than most people of developing those cancers, but not that you will definitely be diagnosed.

Most cancers are caused by acquired (somatic) variants which occur spontaneously during a person’s lifetime, often due to lifestyle and environmental factors. These variants are not passed on to the next generation. Sometimes, cancers can be common in a family but are not due to an inherited gene mutation.

If you do have a genetic mutation, you and your family members can take steps to manage your cancer risks and health care. Children of parents with an inherited cancer mutation have a 50 percent chance of having the mutation themselves.

Discuss your individual circumstances and family history of cancer with your doctor. Seek their advice on whether you should be referred for genetic testing, and which tests to have. Testing is a complex decision on multiple levels, with implications for your family as well. A genetic counselor is highly recommended before and after testing as interpreting the test results can also be complicated.
