What Breast Cancer Awareness Month Ignores

infusion center. Caption: ”The breast cancer awareness walk was terrific! There were balloons, food booths, prizes, and musicians. There was even a bouncy castle for the kids!” Also, an image of the original story on CURE’s website. 

On an October day in 2018, I sat anxiously holding my late wife’s hand to comfort and calm her as she waited for a brain scan. Her doctor suspected her triple-negative breast cancer had spread to her brain (it had).

Earlier I had seen a promotion for a breast cancer awareness walk that looked more like an ad for an Oktoberfest party than an event to raise awareness about a truly horrific disease. It was both angering and heartbreaking to see. At the time, I wanted to write and draw something to express my feelings, but caregiving took priority.

More than a year after my wife’s horrible death in 2021 I wrote this story for CURE, a resource for patients with cancer, survivors and their caregivers. I was surprised CURE published the cartoon and my diss of pinkwashing month events. But I was even more surprised at the hundreds of passionate responses, in messages and as comments on CURE’s social media, who agreed with what I was saying.

Here’s the link to the story:

Talking About Hereditary Cancer

National Hereditary Cancer Week starts this Sunday, September 28th Hereditary cancer is a complicated subject.  Starting the conversation about it does not have to be. An increased risk for some cancers can be inherited.  Genetic mutations that may increase the risk of cancer can be passed down for generations. Many genetic relatives might share the same mutation, even relatives separated by many degrees.  But knowing and sharing family health history and genetic testing  can help prevent hereditary cancer.  Let’s change the way we talk about hereditary cancer. Info & Infographics about Genes, Germline Mutations, and Hereditary Cancer Prevention www.genetionary.org

When my late wife was diagnosed with hereditary cancer, I often found myself trying to explain her cancer and genetic mutations to friends and acquaintances. But hereditary cancer and inherited genetic variants are really complicated subjects. In addition, I soon learned that many people have limited knowledge of basic genomic science. Knowing many people might not understand much about genetics often left me unsure on how to start the conversation. To be honest, it took me a while to figure it out.

So, as National Hereditary Cancer Week draws to a close, I’d like to offer what I eventually came up with. Here are four simple sentences that can be used as the script to start the conversation with those unfamiliar with hereditary cancer and genetics. 

Tens of thousands of cancer cases could be prevented every year. Thousands of deaths could be averted every year. And millions and millions of dollars in treatment costs could be avoided. But the conversation about hereditary cancer risk and the importance of knowing family health history needs to improve drastically if we hope to accomplish any of that.

Let’s change the way we talk about hereditary cancer.

Previvor Day Poster

 Previvor Day Poster graphic.   Previvor Day is a celebration of the courage and strength of those at higher risk for cancer due to certain inherited genetic mutations.   Being a previvor does not mean you will get cancer. Previvorship is about being informed, proactive, and monitored regularly to significantly reduce the risk. Knowledge is power.  Learn more about hereditary cancer at www.genetionary.org

 Previvor Day is still a couple weeks away, but I want to release this now to help raise awareness and understanding of previvorship ahead of the day. As a parent of a previvor, I celebrate Previvor Day as well as all the science that is giving my child a chance at full life cancer-free.

First Contact Revisited

 Cartoon with aliens in spaceships and humans standing in a group: “Attention human in habitants of what you call Earth, We have watched you for millennia and are so now so deeply disappointed to the point we have given up on you ever becoming contributing members of the universe. This short visit will be our last. Your arrogance is annoying and your stupidity overwhelming. You think you are so smart but yet you let ignorance, superstition, and imaginary deities rule your judgement. The lack of compassion for your fellow inhabitants is utterly depressing. For ages and ages you have killed millions of other humans just because they are different or don’t agree with your particular philosophy. And you continue to squander your small planet’s limited resources while destroying the natural beauty of its flora, fauna, and geography with no regard for future inhabitants. should you ever evolve to become peaceful, intelligent beings before you destroy your world we might welcome you back into our cosmic family. Sincerely, The Aliens. P.S. We never probed your butts.”  One male figure is saying, “It’s a government conspiracy!”  Another is saying, “Damn ugly foreigners!”  Another is saying, “Kill em!”  Another is saying, “I wonder is the TV gets sports?” A women character is saying, “World is ending!!”  Another male figure is saying, “Did too probe my butt!” Copyright Mark A. Hicks. www.MARKiX.net. 2016

This cartoon seems more relevant than ever, so I thought I'd repost it.

Yay Yay DNA!

“Yay Yay DNA! Do You Wonder What Makes You You? With Mendel G. Cat.” Art and words by Mark A. Hicks Text: Coming soon to bookstores everywhere . . . . . . a little introduction to genomic science for little readers.
“Explain it to me like I’m six.” 

That’s a quote from an adult. And it was the inspiration for this book.

In 2018 I became a hereditary cancer advocate my child and late wife both tested positive for the same inherited pathogenic genetic mutation. As a hereditary cancer advocate, I have found that, sadly, many adults lack a basic understanding of basic genomic science. So I created something to introduce little ones to the subject so that hopefully when they grow up, they won’t be totally clueless.

Join Mendel G. Cat and learn more about the tiny thin thread that connects all life. Coming soon.

RNA is Life!

 Graphic of cover of book, “Do You Know Peas About DNA?” And the text: Packed in with your DNA is RNA, or ribonucleic acid, a small molecule essential for all life. It works with DNA to produce proteins and other important tasks. There are several different types—mRNA, miRNA,  rRNA, ctRNA, and others—all with different functions. It sort of looks like DNA cut in half. Learn more about deoxyribonucleic acid and other fun stuff when you download this free educational activity booklet PDF. For ages 8 to adult. (Adult? Yes. Too many grown-ups know too little about genomic science.)   www.genetionary.org/DNA

This was created for kids to introduce them to basic genomic science. But damn, there are a whole lot of supposed grown-ups who need to be set down at a desk and given a box of crayons and this book.

Introducing 2025 National Hereditary Cancer Week/Previvor Day Posters

 National Hereditary Cancer Week Posters. One with a colorful illustration of DNA, another with a tree with cancer ribbons.  National Hereditary Cancer Week, September 28 - October 4, 2025. Previvor Day, October 1, 2025. 1 in 279 people are born with an inherited genetic mutation that increases their risk of cancer. Knowing & sharing family health history can help prevent cancer. It’s more than BRCA and breast cancer. Colorectal, ovarian, pancreatic, melanoma, prostate, and other cancers can all be hereditary. Hereditary Cancer is Preventable! Learn more at www.genetionary.org

Hereditary Cancer Week and Previvor Day are still a couple months away, but advocates need to start hanging up posters and playing up the two events to raise awareness. Especially now that it seems like clueless clowns are running the circus and cancer research and prevention are no longer public health priorities. It’s up to us advocates to raise our voices to try and save lives.

The posters can be downloaded here: www.genetionary.org/poster.

Knowing Your Family Health History and Preventing Cancer

 Image of the cover of the booklet, Genetic Inheritance: Tracing the past the prevent disease in the future.  Millions of people have an inherited genetic mutation that can increase the risk of cancer. Most don’t know they have it. Want to know something that is proven to help prevent hereditary cancer?  Family outreach has been proven to be the most effective and cost-effective intervention for early detection and prevention in families with a known risk.  But that’s the problem. Families rarely communicate about family health history. Sadly, many people suffer and die from hereditary cancers that could have been prevented or caught early because of this. As part of its mission to end hereditary disease, ConnectMyVariant.org has created this free easy-to-understand resource. It helps illustrate how connecting with genetic relatives when there’s a known mutation in the family can help reduce disease risk and save lives. Download a PDF of the book at connectmyvariant.org/genetic-inheritance-comic-book

 A comic book-style resource to help grown-ups understand inherited genetic mutations and hereditary cancer risk? Think it’s too simple for adults? 


Think again.

My wife died a very horrible death from a very preventable cancer because some members of her family didn’t understand what an inherited pathogenic genetic mutation was and what it might mean for other members of the family. And this is in a family devastated by cancer over multiple generations.

These relatives knew about the mutation for years, but didn’t share vital information until after my wife’s cancer diagnosis. They obviously needed someone or something to help them understand the big family picture when they received their genetic test results.

When I was asked to volunteer to help create the art for this project, I did not hesitate. However, to be honest, it was emotionally difficult. Working on it kept reminding that my wife’s terrible death from hereditary cancer was so preventable. 

Go to https://connectmyvariant.org/genetic-inheritance-comic-book to download this free book and learn more about CMV’s mission to end hereditary disease by bringing families together.  If you would like a professionally printed version, you can reach out via email at info@connectmyvariant.org.

And please pass this info on! And save some lives!

Peas Mixed with Chromosomes?

Something that I find sad and frustrating as a hereditary cancer advocate is just how little people know about genetics. It's really hard to have a serious discussion about inherited genetic mutations and hereditary cancer awareness and prevention when people have no clue what genes really are and what they actually do.

So I created this free* resource to introduce kids to genomic science. (And with the hope that many adults will find it educational as well.)

Celebrating Previvor Day on Father's Day Again

 Photo of a previvor shirt along with a photo of the artist and author with his baby daughter.

When my daughter was born in 1993, the announcement about the discovery of the tumor suppressor gene BRCA2 was a couple years away. And the coining of the word “previvor” was still several years off. Both of those future events would turn out to be profoundly significant.

In 2017, my daughter had genetic testing and learned she had inherited a mutation in one of her BRCA2 genes. A mutation that we now know to have been passed down in her mother’s family for centuries. That’s right, centuries. Knowledge of the mutation has allowed my daughter to take steps to significantly reduce her cancer risk. She is a previvor.

As part of our effort to raise hereditary cancer prevention awareness, I set out to design a previvor shirt for my daughter. But I soon realized that there wasn’t really a symbol for previvorship. So I sat down at my drawing table and sketched out about a dozen designs before settling on this one. I wanted the symbol to be unique and open for personal interpretation. But with no cancer ribbon in the design.

This coming Father’s Day, I will be celebrating my daughter’s previvorship and courage. And I will also be celebrating the science that has given my child a chance to live a full life cancer-free. A life her late mother did not get.

Hereditary Cancer Red Flags Checklist

 Hereditary Cancer Red Flags -Breast, colorectal, or uterine cancers under the age of 50. -Triple-negative breast cancer. (Breast cancer with no estrogen, progesterone, or HER2 receptors on the tumor.) -Male breast cancer diagnosed at any age. -Two separate cancer diagnoses in the same family member. Example: Both pancreatic and breast cancers in one individual. -Ovarian cancer at any age, especially in younger women. -A known BRCA, Lynch syndrome, or other pathogenic hereditary cancer-related mutation in the family. And that can be in a close genetic relative or one separated by many degrees. -Being of Ashkenazi Jewish descent with a history of cancer at any age. -Multiple family members with the same type of cancer or related cancers (like breast, ovarian, pancreatic, or prostate). -Pancreatic cancer at any age. -Metastatic prostate cancer.

Germline Mutations: Illustrating the Cycle of Hereditary Cancer in Families

GERMLINE MUTATIONS INFOGRAPHIC Illustrating the Cycle of Hereditary Cancer in Families        Found in every cell in your body, your genes control how your body looks, grows, and functions. You have two copies of every gene. You inherited one copy of every gene you have from your mother and another copy from your father. Among the thousands of genes that you inherited are genes that help prevent tumors and cancers from forming. These are called tumor suppressor genes.        Germline mutations are genetic changes that are present in genes in sperm or eggs (germ cells) at the time of conception. Some germline mutations in tumor suppressor genes can increase the risk for developing hereditary cancer. Genetic testing looks for changes in tumor suppression genes that have been linked to hereditary cancer. These particular inherited genetic changes are called pathogenic germline mutations.            It is estimated that 1 in 279 people carry pathogenic germline mutations that may increase their risk of cancer.       Knowledge is power. Learning if you have an increased risk of cancer because of an inherited genetic mutation can help you take steps to detect cancer at an earlier, more treatable stage or prevent some cancers from ever developing. 

After my late wife was diagnosed with hereditary cancer, I quickly learned that trying to explain germline mutations and genetic inheritance to anyone who cared enough to ask questions was not an easy task. Especially since it seemed like a lot of people lacked a basic understanding of biology.

Now that I’m a hereditary cancer awareness and prevention advocate, I try to use my extensive illustration and editorial experience to create infographics that introduce and explain genetic mutations and hereditary cancer on a basic level. I hope it makes it a little easier to understand a very complex subject. And I hope it encourages more genetic counseling and testing and helps save some lives as well.

On Cinco de Mayo

Image of various signs and sheet of rub-on lettering. “Pssst… if you ever see this typeface on anything, or if it’s on your computer system, its real name is La Fiesta. I know because I created it in the late ‘80s. It was a winner in a Chartpak International Typeface Competition. The design was hand-rendered and first produced as rub-on lettering by Chartpak. But when personal computing started taking off, it was pilfered by a fly-by-night software company and renamed.”

Since it's Cinco de Mayo, I thought I'd share this.

Sometimes interesting and sometimes frustrating, a lot of my work has taken on a life of its own over the years. It’s really not unusual to see something I created over the course of my long career being used on the internet or when I travel about. (Sometimes authorized, sometimes not.)

(Ask me about some of my Discovery (Channel) Education Clip Art Gallery images someday.)
