The Tumor

Rate this book
John Grisham says THE TUMOR is the most important book he has ever written. In this short book, he provides readers with a fictional account of how a real, new medical technology could revolutionize the future of medicine by curing with sound.

THE TUMOR follows the present day experience of the fictional patient Paul, an otherwise healthy 35-year-old father who is diagnosed with a malignant brain tumor. Grisham takes readers through a detailed account of Paul’s treatment and his family’s experience that doesn’t end as we would hope. Grisham then explores an alternate future, where Paul is diagnosed with the same brain tumor at the same age, but in the year 2025, when a treatment called focused ultrasound is able to extend his life expectancy.

Focused ultrasound has the potential to treat not just brain tumors, but many other disorders, including Parkinson’s, Alzheimer’s, hypertension, and prostate, breast and pancreatic cancer.

For more information, you can visit The Focused Ultrasound Foundation’s website. Here you will find a video of Grisham on the TEDx stage with the Foundation’s chairman and a Parkinson’s patient who brings the audience to its feet sharing her incredible story of a focused ultrasound “miracle.”

Readers will get a taste of the narrative they expect from Grisham, but this short book will also educate and inspire people to be hopeful about the future of medical innovation.

John Grisham tells us the story of a fictional patient, Paul, diagnosed with glioblastoma multiforme (stage 4). It is a malignant brain tumor where the prognosis of the patient is bad. The author views Paul's treatment from two angles. One is via the angle of current medical literature and current modes of treatment (in 2016 when this book was published), and the second is via the angle of future medical technology (in the year 2025). He is talking about focused ultrasound that can change the future of the treatment of multiple diseases. He shows us how medical innovation can change our future and alter patient's lives in the best possible manner.
"Focused ultrasound is a new, revolutionary, groundbreaking, non-invasive therapeutic technology that has the potential to transform the treatment of a variety of serious medical disorders in addition to brain tumors, improve outcomes, and decrease the cost of care. It could become an alternative to, or complement for, traditional surgery, radiation therapy, and drug delivery”

This is clearly not a book, but propaganda for focused ultrasound.
I don't deny the importance of knowing future treatments for tumors and other lethal disease, I just think this would belong better in a medical magazine or a newspaper..

*Science Progression*

This book is described as a non-legal thriller, but to be honest, it’s not a thriller at all. It’s actually a short story that I could refer to again. John Grisham himself calls it “the most important book he’s ever written.”

The book is about a real new medical technology, but it’s blended with a fictional patient. This technology used today is called Focussed Ultrasound.

Grisham creates a sliding door experience about a man who’s diagnosed with a brain tumour. The man is in his mid-30s, married with three young children, and the different grades of tumour are discussed. We see the scenario of what happens then and then fast forward to the present day, where we see how medical advances today can change the outcome of life expectancy.

This book is a great blend of fact and fiction, and it’s also very educational. This treatment could be used on more conditions, such as Alzheimer’s, which my father has, and some cancers, including prostate, breast, and pancreatic cancer.

Non-legal thriller? It seemed more like a hospital brochure to me. Don't get me wrong, I'm all for spreading awareness about innovations in the field of medicine - the technology that was described is simply incredible, and millions of people would undoubtedly benefit from it. Only issue being, this book was marketed as something that it clearly isn't.

In a break from his usually thrilling legal novels, Grisham dusts off his soap box and presents this piece on cancer and focused ultrasound treatment. The reader is introduced to Paul, a father of three living the idyllic life until he suffers a seizure, which ends up being the early indicator of a brain tumour, a glioblastoma. Paul undergoes the best available treatment in 2015, has the invasive tumour removed, but it recurs and he is eventually forced to come to terms with the end of life. Paul dies and Grisham presents the cost of treatment while stressing that the agony of his family cannot be priced. Grisham postulates that Paul's outcome could have been much different, had he been born and diagnosed ten years later, in 2025. In that time period, a procedure called focused ultrasound treatment would be the mainstream accepted means by which tumours, both benign and malignant, are treated. With this technique, sound and various other waves are used to permeate the tumour and surrounding areas, thereby reducing the intrusive nature of surgery and helping to limit recovery time. Repetitive use of the treatment, for recurring tumours, can be done with ease and Paul would live at least another 50 years to see his children grow. Plain and simple...life is good and the reader can see the benefits of this treatment that remains new and effective. Grisham spends the latter portion of the book arguing that medical and technological logjams are keeping the procedure from reaching those who need it most, at this time, so everyone ought to learn more about it and push the discussion into the mainstream forums, so we can all utilise this procedure with ease. A happy story all around on which everyone can pride themselves for doing their part.

When I stumbled upon this book when perusing Amazon, I was unclear what this was all about. I took the time to access it, for free, and chose to read it in a single sitting. It reads easily and is fairly clear. It is, however, not a Grisham type book. By that, I mean that it does not develop characters or use a strong narrative with nuances that pulls the reader in and makes them feel at one with the topic. Where Grisham has shown readers the troubles with capital punishment, segregation, the falsely accused, and class-action lawsuits, this book fails to do so in a strong fictional (or non-fictional) manner. It reads like a middle school book, complete with hokey photos and diagrams, using easy to comprehend jargon and short explanations. At times, I pined for a subtler approach by Grisham, who could have used a booklet like this as a primer for a wonderful short story and offered the same end result, with the writing flair for which he is so well known. Even if Grisham had ghost written this for the Focused Ultrasound Foundation, I would have had little issue. However, this is not Grisham at his best or even his worst. This is him standing atop a soap box and being preachy without the filter of a well-crafted story to veil the force-feeding approach.

Before I submit this review, I would like to clarify one thing. The poor star allocation that I have offered this piece should not denote my disinterest in cancer treatment or recovery. I must use the quality of Grisham's past work as my threshold, which forces me to allocate so low a mark for this piece. I fully support technological advancements in medicine, especially those who alleviate pain, suffering, and the chance of death. However, writing pamphlets should be left to those who have something to peddle, not New York Times bestselling authors. This is a case of James Patterson Syndrome, where something will sell not for its content, but because a famous author has put his or her name to it. It dishearten me to see that neither the Focused Ultrasound Foundation nor John Grisham himself would have remained truthful and kept this technique from sullying the message.

For shame, Mr. Grisham for using your name to advance something in such a deceptive manner. The cover peddles your celebrity nature and you choose to denote that this is "the most important book I've ever written". While that may be, it was by no means the one with the greatest impact.

This short "book" (67 pages) puts the spotlight on focused ultrasound, a medical treatment procedure involving "intersecting beams of high-frequency sound concentrated accurately and precisely on tissue deep in the body..." The noninvasive procedure is in various stages of development for healing more than 50 diseases and conditions such as Parkinson's and tumors of the brain, liver, pancreas and lung.

The goal, no doubt, is to ramp up awareness of the technology and the need to speed up the approval process for more applications and financial contributions toward the cause. In the interests of full disclosure, Grisham's friend and neighbor Neal Kassell, M.D., a neurosurgeon and proponent, founded the Focused Ultrasound Foundation (based in Charlottesville, Virginia), and Grisham is on the Board of Directors. It's equally important to note that the book is free for downloading at various websites including Amazon.com.

Incorporating narrative and graphics, Grisham outlines the benefits of the technology and how it has the potential to improve both quality and length of life for cancer patients who qualify for treatment. More information, including a link to a video of Grisham's TEDx presentation, can be found at the Foundation's website (links are provided in the book).

Grisham calls this the most important book he has ever written. I call it highly informative and more than worth the brief time it takes to read it.

The Tumor

This is the first time I have ever heard or read about this treatment. Everyone should know about this! What I want to know is why hasn't this been on the news or the newspaper before now? This is an amazing treatment and can really save lives. Thank you John Grisham for writing this amazing book and getting this information out there.

John Grisham says this is the most important book he has ever written. It is a short 67 page book you can read in less than an hour about a fictional character with a brain tumor but the real story behind this is a new technology to treat tumors without the devastating effects of chemo and radiation. Worth reading!!

As a book/story, it was just “OK”, but the purpose of this short story was to promote a potentially revolutionary medical treatment that could save/extend lives.

Given it is super short, it’s a worthy read when you’re between longer books.

This is virtually impossible to review. The Tumor is not a piece of fiction in the usual meaning. I knew before I started the story that it was different and that the intention was to raise awareness of a new medical treatment, and there is no denying that it achieves this aim, but it is not a thriller. It is not a story, it is a case study of what might be possible.
I cannot fault John Grisham for what he is trying to achieve, and potentially this book could contribute to saving lives.
Told you it was impossible to review!
So, two stars for The Tumor as the work of fiction it is presented as, five stars for what it is hoping to achieve.

Grisham states that this short book (47 pages) may be the most important one he has written. Using a fictionalized patient history, he chronicles the potential advantages of treatment by Focused Ultrasound Therapy vs conventional surgery, radiation and chemotherapy in the treatment of brain tumors, and other diseases.

I work in healthcare administration for a major academic medical center and I found this very interesting. Grisham feels it is so important that he will give the book away for the asking. It should be noted, also, that Grisham is a member of the board of the Focused Ultrasound Foundation, and the book solicits donations to further research.

Hit home

This book touched me on a very personal level as I have been dealing with a low grade glioma since 2003. Having undergone 2 brain surgeries, 6 weeks of radiation and chemotherapy, I look forward to hearing about alternate and improved ways of dealing with brain tumors. This book gives me hope. I went close to 10 years between surgeries, so I'll pray that God gives me another 10 to 15 so that i can try this treatment.

John Grisham said this is the most important book he's ever written. It details a new breakthrough technology for treating tumors and other conditions such as Parkinson's and Alzheimer's. It will be an amazing thing to see this come to be in the next 8 years or so. In the example used of a brain tumor, there would be no radiation or steroids needed, and chemo becomes targeted just to where it is needed in the brain and no where else. Amazing.

I really don’t know how I should review this little book. It’s about the possibilities of focused ultrasound which is a technology that can be used to treat cancer, and other illnesses. It sounds like a very interesting technology with a lot of potential. I’m not a doctor, and I don’t have much knowledge about that field, but as far as I know research into this technology has showed positive results. So I get why Grisham would say this is his most important book. With it he is trying to help advance medicine.

However, if I just look at this as a work of fiction, as it is presented, then I can’t say it is a very good book. The characters never come alive because how the story is told, and the plot is just a thinly wailed ad for focused ultrasound. In some sense I have more respect for John Grisham now knowing that he has, with this book, written something that is mostly to benefit others. Something close to his heart. If only he had actually managed to make a good story with this material, but in my view it never becomes a strong story. Perhaps it would actually have been better if he had just written a nonfiction book about the subject, but maybe fewer people would have read it then. Still, if you’re interested in this technology it’s worth a read. It’s short, and free. You can listened to it here: https://www.youtube.com/watch?v=c4aHd...

John Grisham ends "The Tumor" on: "This is the most important book I’ve ever written." –John Grisham
Wow!

I'll admit that this book caught me by surprise, by double surprise.
Though I haven't read a book by Grisham in a long time (read: A Time to Kill, The Firm, The Pelican Brief, The Client, The Runaway Jury) I thought I could guess what I'd receive when I picked up "The Tumor" on free promo. No, I didn't read the book's description; the whole world knows that John Grisham writes courtroom drama so I thought that's what I'd get.

Surprise #1: 'The Tumor' tells the real life story of Paul, a 35-year-old banker, an exceptionally healthy man, his wife, Karen, and their three young children. Even though Paul jogs twenty miles a week, plays golf, doesn’t smoke, and takes no medication, out of the blue Paul experiences some health problem which he contributes to stress on the job. Sooner after, he has a seizure and passes out. Tests reveal he has a brain tumor, which turns out to be the most catastrophic, glioblastoma.
It seems to me that's the tumor John McCain was diagnosed with. For sure Ted Kennedy, Beau Biden, Lee Atwater, George Gershwin, and Wilma Rudolph died from a glioblastoma.

In typical Grisham style the story moves forward quickly, alas, no last minute brilliant lawyer intervention is possible - Paul dies.

Why is Grisham telling the story? Because a cure will be possible in the (relatively near) future - the best kept secret in medicine - focused ultrasound. No invasive surgery, no draining treatments, no exhausting, maybe not really working chemo therapy.

Surprise #2: Grisham wants to speed up the development of the procedure. He is on the Focused Ultrasound Foundation Board of Directors , hence lent his talents to tell the story right to this awesome cause.

For me, that's where the circle closes. The book is again the story of a few brave men and women, who don't wait for pharmaceutical corporations to develop new expensive chemo therapies. In comparison to the big pharmaceutical corporation the Focused Ultrasound Foundation is like that clever small town lawyer who does the right thing and "fights for the cause."

Whoever you are who reads my review:
Grab "The Tumor" by John Grisham. It's free. Read it, study it, and maybe donate. You are one of your loved ones may need this book's knowledge in the future.

Deeply impressed and grateful,
5 stars,

Came across this, and found his altruistic spirit moving enough to compel me to read the book. Only 52 pages, and it gives you a close-up of outdated vs. modern technology, with its benefits, costs, and effects all quite literally portrayed.

It isn't a book up you pick up to enjoy your daily bout of escapism. It's to inform you of what's out there, and that we're still blessed to be in an age where such medical treatment is possible. Grisham's writing style is nothing like his usual. It doesn't grip you into believing you're a (often) snazzy lawyer, taking your chances against the world. It describes a life afflicted by malignant tumors, and the domino effect that it causes.

This could easily have been a really well designed hospital pamphlet. Instead, by form and style, it has turned into something more. It informs, and it urges its readers to understand what is really available to them already, and what they can do about it. This is what writers should do, when they know they've got a solid fan-base, and they will be heard, regardless of what they write.

Write fiction, write responsibly, and write to not only entertain, but also to save lives. That's what makes a author unforgettable, even if its just for an age.

This is free on Amazon and well worth a read. It's very short, 67 odd pages including some pages of diagrams and credits so you will read it in no time.
It's shining the spotlight on a new treatment for various diseases including brian tumours and has a story of a thirty something married guy with kids diagnosed with a grade four malignant tumour.
The tumour is unfortunately incurable and we get the story of the process of treating it in the present day and the suffering that entails and then from the perspective of the same diagnosis in ten years time, where the patient is treated with the new treatment, focused ultrasound.
It concludes with details about this treatment which is still in its infancy and its potential(and current) uses in helping in the treatment of cancer amongst other things.
I, like many I suspect, had never heard of focused ultrasound therapy before and if the words written are to be taken at face value, could be a huge step forward in the treatment of many cancers in the years to come.

Most, if not all of us have been affected by cancer in our lives in some way, so I'm sure this will be of interest to everyone. It takes little effort to read, being so short and is more like an information leaflet than a book, with a very short story in the middle to demonstrate the the treatment it is espousing.

If you have a few minutes spare I would certainly recommend giving this a read. It could be a little glimpse into the future of the treatment of cancers in the future and its all the more startling, not just by the effectiveness of the treatment over current methods, but also the nature of both treatments, with the sheer brutality of current methods being in stark contrast to the non evasive, walk in walk out nature of focused ultrasound.

High Intensity Focused Ultrasound (HIFU) is a medical device for brain tumors developed & being approval. Paul(35) has "Glioma" (left side brain) tumors causing blackouts. Paul undergoes treatments for brain tumors, followed by chemotherapy & radiation treatments. The cancer is "malignant", life expectancy is 12 months & he dies in 9 months.

HIFU can diagnose "brain tumors, Parkinson’s, Alzheimer’s, hypertension & other cancers." With HIFU, Paul received "outpatient" brain treatments & returns to a normal life. After 3 years, Paul gets the cancer again, treatment again, with positive results.

Grisham says the cancerous tumor occurs again but future research will improve the process.
The book introduces the Focused Ultrasound Foundation from Ed Miller, M.D., of Johns Hopkins, stating "Grisham has pulled an exciting new medical technology out of the labs of academic research and onto the pages of an enlightening book."

Do Miracles Still Happen?

What if finding out that your loved one had aggressive Stage 4 cancer, or Parkinson's, or malignant lymph nodes was no longer a death sentence but instead, a very treatable condition. I have 3 such loved ones right now who would love to hear they could be treated with non-poisoning, non-invasive outpatient therapy.

ThisI story isn't a novel, not science fiction. It would be a very real and affordable hope for the future of modern medicine if the Focused Ultrasound Foundation and varied research associates could move forward by breaking through the concrete ceiling built by pharmaceuticals, insurance companies and government (hand-in-the-pocket) lobbyists.

Get the word out! Fight for better health care! Make a difference!

How wonderful it would be if everyone read this book and made even a small donation. It could make a huge change for people who are diagnosed with deadly glioblastoma brain cancer along with other diseases. This book is free and you can easily read it in about 30 minutes. Read it, make a donation and save the life of a loved one!

This book is a pitch to promote the potential impact of focused ultrasound: today’s medical story could become tomorrow’s lifesaving reality.

A free book although small 67 pages from John Grisham I couldn’t resist although I admit to have skipped the synopsis and the size of the book after all Grisham’s books are excellent…non.

We have in this story two scenarios:

The first starts with a fictional Paul receiving a diagnosis of a lethal brain tumour and the painful battle he and his family go through till his death.

Spring ahead 10 years in the second story is on focused ultrasound technology and its potential to change lives. Paul undergoes the treatment and his life is spared for many years.

This is not a thriller but rather a pamphlet and a promotion for a foundation looking into focused ultrasound. Great cause but advertising is advertising….
