A recent news story in the Journal of the American Medical Association (JAMA) reminds me that lots of things in our lives are changing these days, not the least of which is the shape of our bodies.
Oh, my. This aging thing isn’t so easy, and that is really the message behind Rita Rubin’s timely piece about shifting body mass and muscle as we age and its implications. Although focused on women, I can attest personally that men fall into the same trap as well. That 250 pounds when you are older simply is not the same 250 pounds when you were in college. Now 250 pounds looks more like 280—even though the scale still says 250. Go figure…
Although I may be trying to provide a little humor to the subject, the reality is it’s not humorous when it comes to our health. As we age, muscle turns to fat. In a process called “sarcopenia,” muscle begins an inexorable march to become fat, and for most of us it doesn’t make too much difference how much we try to forestall the shift. It is programmed into our bodies, and although exercise might help, Mother Nature simply doesn’t … Continue reading →
A recent research report on melanoma from the Centers for Disease Control and Prevention received virtually no notice, yet one of the statistics in that report was—at least for me—stunning, and marked a rare public health win.
People in public health know all too well the gap between educating people about cancer risks and seeing actual results. Skin cancer is no different: We have known for many years that the risk of skin cancer is related to exposure to UV radiation, either from the sun of for indoor tanning.
Yet despite widespread efforts to educate people about this very real cancer risk, we haven’t made much progress reducing its frequency—at least until now.… Continue reading →
4.9 million—yes, million— people are diagnosed with skin cancer every year in the United States. It costs an estimated $8.1 billion—with a “B— to treat those skin cancers, according to the Centers for Disease Control (CDC).
Do I have your attention? I hope so. The problem is we don’t have enough attention. There is no other way to explain why too many states still allow those under 18 to access tanning beds across this country.
Have we made progress? Yes, but not nearly enough according to a research paper and editorial published today in JAMA Dermatology.
The study, from the CDC, looked at surveys of high school students done every two years between 2009 and 2015. The researchers found that overall the frequency of tanning bed use in the previous year declined from 15.6% of all high school students in 2009 to 7.3% of all students in 2015.
That’s progress. However, when they took a closer look at different groups of students they found that among non-Hispanic white female students the numbers using a tanning bed the previous year dropped from 37.4% to 15.2%.
Sound good? Maybe—until you look at the percentages for those 17 and older: in … Continue reading →
After years of declining rates of colorectal cancer (CRC), a new study from the American Cancer Society raises the specter that not all is going as well as we would have hoped, especially among younger folks born since 1990. And that raises the question of what the future holds for this frequently preventable form of cancer, including a possible reexamination of when it is appropriate to start CRC screening for people at average risk of developing the disease.
The research, published today in the Journal of the National Cancer Institute looked at the rates of colon and rectal cancer diagnoses from 1974 through 2013 in several parts of the country. The researchers were particularly interested in changing patterns of CRC in people 20 years of age and older who were diagnosed with invasive CRC from 1974 through 2013.
There is a lot of complexity in the published results, so let’s focus on the main messages of the study:
- After decreasing since 1974, colon cancer incidence rates increased by 1% to 2% per year from the mid-1980s through 2013 in adults ages 20 to 39. In adults 40 to 54, rates increased by 0.5% to 1% per year from the

I am devoted to my fitness tracker, having used it for several years to remind me to be active, monitor my diet and improve my sleep. Now the New York Times tells me it doesn’t make a difference, at least when it comes to the weight loss part of the program. And I might agree, if only the evidence they relied on told the whole story. In my opinion, it did not.
Unfortunately, some of the science on which the Times’ reporter based his comments had a possible flaw that may influence the conclusion that fitness trackers not only don’t encourage weight loss, but improbably may lead to less weight loss when using the device.
That, my friends, would be a real bummer. However, if you had evaluated that research closely you may have been aware of the problem. From where I sit, I don’t think many folks have made that effort. And I remain unconvinced that the research supports the conclusion that fitness trackers–when used in typical real-life situations–don’t make a difference in keeping us engaged in our health including as an adjunct in weight loss programs.… Continue reading →
The American Cancer Society has now released its newly updated Breast Cancer Screening guideline in the Journal of the American Medical Association
This guideline—which was last updated in 2003—reflects the American Cancer Society’s best thinking on breast cancer screening for women at average risk of breast cancer. They are not intended for women at high risk, such as those with genetic abnormalities (BRCA as an example), a personal history of breast cancer or a history of radiation therapy prior to age 30. That guideline is available on our website at www.cancer.org.
So let’s get right to the heart of the matter: what are the new recommendations?
- Women with an average risk of breast cancer should undergo regular screening mammography starting at age 45 (Strong recommendation*)
1a) Women aged 45 to 54 years should be screened annually (Qualified recommendation*)
1b) Women 55 years and older should transition to biennial screening or have the opportunity to continue screening annually. (*Qualified recommendation)
1c) Women should have the opportunity to begin annual screening between the ages of 40 and 44 years (Qualified recommendation*)
2) Women should continue screening mammography as long as their overall health is good and they have a life … Continue reading →
I just noticed this blog celebrated its 10th anniversary this September. So I hope you won’t mind me taking this opportunity to share some observations and reminiscences of what it’s been like to document by blog a decade of the changing landscape of cancer.
The first blog was published on September 9, 2005 when I introduced the blog and my vision for what i hoped it would represent.
The blog originated with a concept developed by our media relations team. Social media was just coming into prominence, and the Society was looking at ways to get into this space. Bob Lutz, a senior executive at General Motors at the time, was the model: he wrote a regular blog himself, and was pretty open in sharing his thoughts. It was clearly not one of those ghost written, pre-packaged types of things. How he found the time to do a blog was an interesting question, but the concept was intriguing: if we could have one of our senior folks write something similar, perhaps it would get some recognition in this rapidly expanding means of communicating.
So we ventured into the space and I started writing “Dr. Len’s Blog”. One of … Continue reading →
It has been said that with knowledge comes understanding.
A research paper and editorial published in this week’s issue of JAMA Oncology may have brought knowledge, but if you read various media reports I am not so certain it has clarified understanding. And the distinction is important, because when a woman is confronted with the diagnosis of a “Stage O” breast cancer (aka ductal carcinoma in situ or DCIS), the decisions she makes about treatment can have far-reaching and long lasting impact for her and those who care about her. [more]
First, some brief background: DCIS was rarely diagnosed before the advent of mammographic screening for breast cancer. Perhaps it was found incidentally when a breast biopsy was done for another reason, or perhaps a woman or her physician felt a mass that turned out to be DCIS. Once mammography became more widespread in the 1970’s, we began to see a marked increase in the number of women diagnosed with DCIS. Today, the American Cancer Society estimates that in 2015 slightly more than 60,000 women in the United States will be diagnosed with this lesion (compared to 234,190 women who will have a more typical invasive breast cancer).
The situation … Continue reading →
Fate can work in mysterious ways.
A couple of months ago I was invited to participate in a symposium conducted by the National Cancer Policy Board at the Institute of Medicine in Washington DC. The topic was cancer in dogs, and how we might find ways to benefit dogs, their owners and science to better inform the treatment of cancer in humans through what is called “comparative oncology”. It was an unusual topic in my experience and that of my colleagues, so I eagerly anticipated learning about something I hadn’t given much consideration to in the past.
Little did I know at the time how personal this journey was going to be for me and my family.
Shortly after I accepted the invitation, we received sad news: our Golden Retriever Lily-who has been a member of our family for 11 years-developed swelling in her face. Our vet saw her the next day and told us she had lymphoma. The outlook without treatment wasn’t good, and with treatment wasn’t much better.
Tears flowed in our home that evening.
A week later we found a mass on Lily’s back leg. Another trip to the vet, another needle biopsy, and another … Continue reading →
It’s October and that means we are about to see a lot of pink for the next 31 days. And virtually all of the work comes down to one simple -some might say overly simple-message: get a mammogram.
But as National Breast Cancer Awareness Month (NBCAM), begins, I find myself one again asking some difficult questions: Are we really looking at the right side of the equation? Is it all about mammograms? Is there more to the story? The answer is absolutely unequivocal and without a moments hesitation: YES! [more]
There’s no doubt NBCAM is a big deal. In fact it’s probably the biggest cancer care effort for the entire year. It has been enormously successful in bringing attention to breast cancer and creating public focus on a very important issue for women and the men who love them, even as it does crowd out attention to other cancers that also deserve our attention, like lung, childhood cancer, ovarian cancer, and on and on.
And why shouldn’t we highlight mammography’s role? In the bad old days, as a much younger oncologist, I used to dream of a day when we could have not only better treatments for cancer, … Continue reading →
