blood type and cancer risk

5.20.25 ~ North Carolina Botanical Garden

I can’t stop thinking about something a naturopathic oncologist told my sister, who was recently diagnosed with endometrial cancer, the same kind of cancer I had. Apparently having blood group A is associated with an increased risk of cancer, and blood group O is associated with a decreased risk of cancer. Both my sister and I have type A blood.

Coincidentally, a few days after learning this, while going through another one of my family history boxes — I’m now on box #6 of the 14 — I found my mother’s blood type A identification card from the Dana-Farber Cancer Institute, where she was receiving treatment for metastasized breast cancer in 1990. She died when she was 59, in spite of four years of surgery, radiation and multiple chemotherapies.

As I was pondering the significance of now knowing her blood type, it hit me that her father, my grandfather, had prostate cancer. (I have no way of discovering what his blood type was.) With some aggressive treatments he survived his cancer and lived to the age of 95.

And then I started wondering about my grandfather’s parents. Locating his father’s death certificate I discovered that he died at age 75 of adenocarcinoma of the transverse colon, metastasis to liver. He had surgery in August of 1948 and died in July of 1949.

Finding these connections for four generations in a row is unsettling, as looking closely at genograms can often be. If I could trace it I wonder how far back the cancer line would go. All my children have type O blood so likely they will be spared from this specific cancer risk factor.

The gene for type A blood is dominant, and the gene for type O is recessive. Which means I have a recessive O gene that I passed on to my children. (They got their other O gene from Tim. One needs two O genes to have type O blood. Tim also has type O blood so that’s the only kind of gene he could give them.) It surprises me that none of them got the dominant A gene from me because the law of averages suggests that half of my children could have received it and had type A blood!

Until my sister consulted one, I never knew that naturopathic oncologists existed. After witnessing the nightmare I’m living through due to radiotherapy aftereffects she is not interested in submitting to the same recommended treatment for her cancer. We both are of the mind that sometimes, for some people, quality of life is more valuable than a prolonged quantity of life. It will be interesting to see what things we will learn about other treatments from this alternative, integrative physician.

Meanwhile, the current administration continues its efforts to cut funding for health care and cancer research. And now this:

If you’re under 65 and don’t have a chronic condition, there’s a very real chance you won’t have access to a Covid-19 vaccine this fall. Much depends on what happens next month. ACIP could defy the FDA and recommend vaccines for broader use, but that would be risky. We’ve never been in this situation before. ….. This isn’t about whether everyone needs a yearly Covid-19 vaccine—that’s a legitimate, ongoing scientific debate, and one ACIP was already tackling in June. This is about how decisions are made—and who gets to make them. FDA political appointees are sidelining expert panels, bypassing transparency, and turning public health into a performance. That might fly in other arenas, but shouldn’t when it comes to people’s health and daily lives. ….. Vaccine decisions must be rooted in evidence, debate, and transparency. ….. If this is the new model, we should all be alarmed.

Closer to home, last summer I endured three episodes of seed tick bites on my legs following walks in the botanical garden. I thought I had solved the problem by using recommended permethrin as a repellent but when I took a walk there on Tuesday I was attacked again and now have 9 bites. I’m done! The pictures in this post are not worth the price I’m paying to have gotten them!

Yesterday was a great weather day! We took advantage of rare low humidity and temperature and scooted over to the botanical garden. There were many bugs out and about, doing their summer thing. I’m suffering from another batch of spider bites on my legs and I have no idea how they’re getting there. (I now know they’re spider bites because my reaction rash is so bad it drove me to a dermatologist. She was mystified and had a biopsy done on the rash to see what was causing it. I hope I won’t need another round of steroids!)

I hope you enjoyed the glimpse into the buggy summer botanical garden. Creepy crawlies go hand in hand with pretty flowers. I’m biding my time until autumn arrives!

a flooded cypress swamp

2.20.24 ~ Colleton State Park, Walterboro, South Carolina

On our way home from Georgia we stopped to stretch our legs at a state park in South Carolina. The nature trail we walked on followed a cypress swamp alongside the Edisto River. This river is the longest free-flowing blackwater river in North America and on this day it was flooding over into the swamp.

A blackwater river is a type of river with a slow-moving channel flowing through forested swamps or wetlands. Most major blackwater rivers are in the Amazon Basin and the Southern United States.

some of the water came very close to the trail

When we talk of flood control, we usually think of dams and deeper river channels, to impound the waters or hurry their run-off. Yet neither is the ultimate solution, simply because floods are caused by the flow of water downhill. If the hills are wooded, that flow is checked. If there is a swamp at the foot of the hills, the swamp sponges up most of the excess water, restores some of it to the underground water supply and feeds the remainder slowly into the streams. Strip the hills, drain the boglands, and you create flood conditions inevitably. Yet that is what we have been doing for years.

This magical rest stop helped so much to break up the long journey home. The walk was a only a third of a mile, a perfect finale to a wonderful getaway. And it was so good to get home to North Carolina a few hours later.

songbirds, blooms, some other things

There were lots of birds at the botanical garden feeders on Valentine’s Day, most of them flitting about too quickly to catch with my camera, but I got a few. And a new lifer!

Pine Warbler, #81

I thought I’d never catch my elusive new life bird — this was the only good picture out of the bunch.

A bird true to its name, the Pine Warbler is common in many eastern pine forests and is rarely seen away from pines. These yellowish warblers are hard to spot as they move along high branches to prod clumps of needles with their sturdy bills. If you don’t see them, listen for their steady, musical trill, which sounds very like a Chipping Sparrow or Dark-eyed Junco, which are also common piney-woods sounds through much of the year.

We’ve been hearing frogs croaking for a couple of weeks but they always stop and hide before we get to their pond, no matter how quietly we approach. This time we did see a lot of their eggs in the water, though.

One of these days we might actually see a frog! 🐸

Cypress knees (above) are woody projections sent above the normal water level in the root of a cypress tree, usually seen in swamps. They may help to provide oxygen to the trees and may help to support and stabilize the cypress trees in the soft, muddy soil.

Spanish moss (below) is a bromeliad that hangs from oak or cypress trees. The plant has no roots and absorbs nutrients and water from the air and rainfall.

On the night of a full moon, April 6, we took an enchanting sunset cruise on a small skiff into the Okefenokee National Wildlife Refuge. There had been a natural fire, started by lightning, about a year ago.

In southern Georgia and northern Florida there is a very special place, one of the oldest and best preserved freshwater systems in America. Native Americans called it Okefenoka, meaning “Land of the Trembling Earth.” Now this place, where earth, air, fire and water continuously reform the landscape, is preserved within the Okefenokee National Wildlife Refuge, created in 1937 to protect wildlife and for you to explore.
