Do Fitness Trackers Help Us Lose Weight? The New York Times Says “No”; I Say “Not So Fast”

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 Updated Breast Cancer Screening Guideline From The American Cancer Society

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?

  1. 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) Continue reading →

10 Years And Half A Million Words…

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 →

New Research On Ductal Carcinoma In Situ (DCIS) Brings Knowledge–Now We Need Understanding

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 →

Some Of The Answers To Cancer Care May Be Found With Our Companion Dogs Walking Right Beside Us

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 →

Breast Cancer Awareness Is About More Than Mammograms: What You Need To Know

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 →

Ultraviolet Bad: Surgeon General Issues A Call To Action To Prevent Skin Cancer

(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.)

 

“Ultraviolet bad.”

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. [more]

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 →

“Don’t Fry Day” Reminds Us To Take Care Of Our Skin Since It’s The Only One We Get

“Don’t Fry Day,” which we “celebrate” every year on the Friday before Memorial Day is an annual reminder to be good to the skin you’re in. It’s the only one you get. Wear it out or damage it and you don’t get to replace it, like we do with heart valves, knees, hips, and so on.

This year Don’t Fry Day is even more personal to me. After hounding all of you to be careful in the sun, I got a very personal reminder this past year of why that’s important: two surgeries and two scars from removing skin cancers. One of those scars is pretty visible and a daily reminder of my own past unwise sun behavior. Like many folks, I’m glad the cancer is gone. But I also wish it hadn’t been there in the first place.

The reality is that my generation had very little knowledge and very few options when it came to avoiding the dangers of too much sun exposure. We went outdoors, we went to the beach, we didn’t have sunscreen, and we just lay there and took it. We thought we looked good. If we worked outdoors–like I did when I was … Continue reading →

One Doctor’s Confession: Basal And Squamous Cell Skin Cancers Are NOT Benign

I have made a resolution for 2014: I will never, never, never again call basal and squamous skin cancers “benign” cancers.

Why would I make such a strange commitment? The explanation is simple:  I spent 4 hours on New Year’s Eve sitting in the surgeon’s chair getting a skin cancer taken off my nose. Nothing about the experience fits the “benign” label so many professionals, including yours truly, have used:  routine; easy to treat; nothing to worry about.  Friends, after this experience, which left me looking like a tall, white-haired Rudolph the Reindeer, I am here to tell you these cancers are not to be trifled with, and are worth every effort you can make at preventing them by reducing exposure to UV radiation. [more]

This was the second time in the past 6 months that I had surgery for one of these “benign” cancers. The first time was difficult enough (see my earlier post), so when I saw a small growth that progressed over time, I made it a point to get to the dermatologist to get it removed. He did. That part was fairly simple. But a week later I got the call: “You need to … Continue reading →
