Don’t avoid all sun exposure
Vitamin D just won’t get out of the news. I posted about it a couple of weeks ago, and here I am commenting again on something else I read.
Actually, a friend sent me a link to a health care blog that referred to a recently-published study out of Sweden. Swedish melanoma researchers followed almost 30,000 women (I’m not sure why just women) for 20 years and concluded:
We found that all-cause mortality was inversely related to sun exposure habits. The mortality rate amongst avoiders of sun exposure was approximately twofold higher compared

The Doctor Mole skin cancer detection app
I was browsing through some smartphone apps last week and I ran across one called Doctor Mole. At first I thought it had something to do with the garden pest—I have an infestation of moles plowing through my vegetable garden every evening, so they are much on my mind.
I thought, “Yes! An app to tell me how to get rid of moles!”
Nope. Wrong kind of mole.
But I was still interested. I had heard of these skin cancer tracking apps, so I decided to take a look and see what … Continue reading
Here comes the sun
Although sunscreen could and should be used year-round, we buy more sunscreen products in the summer months. And it’s a good time to stock up on your favorite product, because this is also when you’ll find the best sales.
But do you know what to look for when choosing a product? Do you understand what SPF means and which ingredients offer effective protection? If you aren’t reading labels, and are judging by brand, price or marketing claims alone, you might not be getting the best deal.
UVA and UVB rays
First, why use sunscreen at all? … Continue reading
Mouthwash possibly linked to oral cancers
Earlier this month, a group of dental researchers in Glasgow, Scotland reported a link between frequent use of alcohol-based mouthwash (3 times per day) and oral cancers, such as mouth, throat, tongue and vocal cords.
A similar study came out of Australia in 2009. The theory is that alcohol “increases the permeability of the mucosa” to carcinogens, such as nicotine or acetylaldehyde (a breakdown product of the alcohol).
But other analyses have found no such significant link.
Certainly smoking, chewing tobacco, drinking and poor oral health are all risk factors for developing oral … Continue reading
The latest report
Most of my nursing career was in breast cancer, so I like to stay current on the most recent research on screening, diagnosis and treatment.
Earlier this week, the British Medical Journal released a pretty stunning report:
In conclusion, our data show that annual mammography does not result in a reduction in breast cancer specific mortality for women aged 40-59.
In normal language that translates to “annual mammograms don’t save lives.”
Aaron Carroll, MD, writes on his blog:
This study is going to make a whole lot of people upset. It’s a large, well designed

Screening guidelines often don’t agree
One of the mandatory benefits of health insurance, thanks to Obamacare, is that preventive or screening services are covered without charging copays or coinsurance.
Preventive care is not really “free,” of course, because we pay higher premiums and higher copays and deductibles for other health care. It’s more like pre-paid.
(Oh, and make sure the doctor and testing facility (lab or radiology) are in your network, or the care won’t be covered.)
But I’ve found it more and more confusing to know which screening exams are covered, and how often, because different medical “authorities” seem … Continue reading
A son’s anguish
Have you ever read the comic strip Dilbert?
Created by Scott Adams, it is a wonderfully humorous and satirical cartoon about a white-collared worker, Dilbert, who exists in a world of partitioned office cubicles and micromanaging bosses. It’s very funny.
But this morning I ran across Scott Adams’s blog and read his very angry, very painful, very un-funny post about his dying father.
I hope my father dies soon.
My father, age 86, is on the final approach to the long dirt nap (to use his own phrase). His mind is 98% gone, and all he has

One woman’s unwitting contribution to medicine
I’m always interested in medical ethics news, and a few days ago I saw Henrietta Lacks’s name mentioned.
Who is Henrietta Lacks?
She was a poor, African-American woman who, in 1951, died at the very young age of 31 from an aggressive form of cervical cancer. Sadly, she left behind five young children.
A research team at Johns Hopkins, where she was treated, collected some of her cervical cells. Mrs. Lacks was never informed or asked for consent; it was 1951, after all, and the concepts of patient rights and privacy were basically non-existent.… Continue reading
Increased risk of breast cancer reported
A new study published in the Journal of the American Medical Association reports that women who have taken a certain type of medication—calcium channel blockers—for more than 10 years to treat high blood pressure are at increased risk of developing breast cancer.
The study is observational, meaning that it looked at data from a large group of women who had already been diagnosed with breast cancer.
Increased risk of breast cancer was not seen in the women who had high blood pressure but took other types of medications, such as diuretics and beta … Continue reading
Flight delayed? Learn CPR!
For the next six months, Dallas-Fort Worth airport is hosting a trial program to teach “hands-only” CPR to travelers. An automated kiosk, developed by the American Heart Association in partnership with American Airlines, guides passengers through a simplified CPR technique using video instructions and a manikin torso. If the program is successful, it will be expanded to other airports.
Hands-only CPR does not require rescue breaths and is as effective as regular CPR. It sounds like a useful way to pass some time, and I’d love to try it if I’m ever in one … Continue reading
