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 →
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 →
(Note: This blog was originally published on another American Cancer Society website on July 29 because of technical problems on this site. Those have now been resolved and it is now reposted here. We appreciate your understanding.)
That was the core message that came out of the introduction Tuesday morning of the Surgeon General’s Call to Action to Prevent Skin Cancer at a meeting held at the National Press Club in Washington DC.
There were some other messages that now raise skin cancer awareness and prevention high on the public health awareness list, such as the fact that over 5 million people every year have a diagnosis of skin cancer (and many have more than one skin cancer), and that we are spending over $8 billion dollars treating the disease. But most important is the fact that this is one of the most preventable cancers, and if current trends are any indication we are not getting the job done when it comes to decreasing the number of skin cancers and saving lives.

Acting Surgeon General Boris Lushniak MD and Assistant Secretary for Health Howard Koh MD were masterful presenting the evidence contained in the report, and … Continue reading →

I had the privilege this week to serve as the keynote speaker for the 4th Summit sponsored by Latinas Contra Cancer-an organization founded and led by Ysabel Duron, a formidable cancer survivor and news media presence in San Francisco.
Bringing together members of the Latino community, researchers, community health workers, promotores (more on that later) and advocates, the summit focused on the issues facing the Latino community in increasing awareness, access to care, improved treatment and research opportunities among other topics. But what was most impressive was the spirit, engagement and commitment that permeated the room for the two days of the meeting.
I would like to share with you some of what I learned during the preparation for that lecture, as well as some observations that tie together the impact and calls to action that are relevant to the Latino community and many other ethnic and socioeconomic groups in the United States. (You may wish to refer to the American Cancer Society’s “Cancer Facts and Figures for Hispanics/Latinos 2012-2014” which contains a wealth of information relative to cancer for this community.)

When one takes a closer look at the Latino community, one finds there are … Continue reading →
This past week I had the privilege of participating in a meeting hosted by the President’s Cancer Panel on the role of social media in improving cancer control and treatment. The goal was to give advice to the Panel on a planned series of meetings they will be convening to discuss the topic. It was the range and quality of the discussion that day that left me thinking about the broader topic of social media and how it could help improve cancer control going forward. [more]
I do not profess to be a social media expert. I do (obviously) engage in social media in a couple of ways, primarily through my blogs and Twitter (@DrLen), but I am not an addict. And notwithstanding the fact that social media has become a standard communication format for many folks, especially the younger generation, I still wonder how we are going to harness this revolution to improve what people know about cancer, what we can do with that information and how we can raise awareness about cancer-related issues such as new treatments, prevention, survivorship and clinical trials among many other topics.
The reality is that there hasn’t been much impact of social media … Continue reading →
An article published this week in the American Cancer Society journal CA: A Journal for Clinicians received a lot of media attention. The report showed dramatic declines in the rate of people being diagnosed with colorectal cancer, as well as decreases in the rates of colorectal cancer deaths over the past number of years.
But the press didn’t say much about the fact that not everyone has benefitted from the progress we have made in the prevention, early detection, and improved treatment for colorectal cancer. It is a sad but very real commentary on how we approach health care in this country that African Americans have not benefitted equally from this progress in treating a cancer that for many people can be prevented or effectively treated when found before it spreads to other parts of the body.
As a nation, I believe it is incumbent that we address this glaring health disparity. To do less is unacceptable. [more]
Here are some examples from the research report:
1) During 2006 to 2010, colorectal cancer incidence rates in blacks were approximately 25% higher than those in whites, and 50% higher than those of Asian-Pacific Islander descent
2) A larger disparity exists … Continue reading →
