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!

Presenting to you even more flowers enjoying the sunshine. They were being visited by lots of bees, butterflies, and dragonflies. And other pollinators we didn’t notice, no doubt. We did have a south wind, a breeze actually, which made some of the flowers almost as difficult to photograph as the ever-in-motion birds.

Bumblebees come —
Hover — hesitate —
Drink, and are gone —

Butterflies pause
On their passage Cashmere —
I — softly plucking,
Present them here!

Unlike Emily, I didn’t pluck any of the flowers, but have presented them to you by way of photographs instead. There is always something new (to me) growing at the botanical garden, and it’s also fun seeing the familiar plants and noticing how they keep changing with the circle of the seasons.

We chanced across a patch of yet another species of trillium. This lance-leaved trillium is the 12th kind of trillium I have pictures of on this blog. There are about 50 known, worldwide.

Last fall when we saw the huge leaves falling down around the bigleaf magnolia I did some research and learned that people often miss seeing the flowers in the spring because they are so high up in the tree. So I’ve been looking up on every visit since spring got started. On this day I saw some buds and new leaves emerging and used the zoom lens to get a picture. (above)

Mountain witch-alder or large fothergilla is a 6-12 ft., sometimes taller, deciduous shrub with picturesquely crooked, multiple stems. Dense, dark blue-green, leathery foliage becomes colorful in fall. The fragrant flower, appearing as a mass of stamens, is white and occurs in thimble-like, terminal spikes after the leaves have appeared.

Maybe the sunlight was different this year but the Spanish lavender’s hues seemed a lot deeper, compared to last year’s photos. I love this vivid color!

Everything outdoors is filled in and green now! I came home with hundreds of pictures Sunday afternoon and struggled to narrow my selections down to 36, so I’m splitting them down to sharing a dozen a day for three days.

We were delighted to find a pair of house finches enjoying a late lunch at the feeders.

And then there were plenty of flowers, of course!

I noticed this well-defined fern shadow on the boardwalk (above) and then found the beam of sunlight on a Christmas fern (below) that was creating it.

The cinnamon ferns (below) have grown so tall since I photographed their fiddleheads on March 26th!

Blooming wild azaleas scattered around the botanical garden looked so pretty there, accenting all that new greenery.

they are for what they are

These roses under my window make no reference to former roses or to better ones; they are for what they are; they exist with God to-day. There is no time in them. There is simply the rose; it is perfect in every moment of its existence. Before a leaf-bud has burst, its whole life acts; in the full-blown flower there is no more; in the leafless root there is no less. Its nature is satisfied, and it satisfies nature, in all moments alike. But man postpones or remembers; he does not live in the present, but with reverted eye laments the past, or, heedless of the riches that surround him, stands on tiptoe to foresee the future. He cannot be happy and strong until he too lives with nature in the present above time.

Even though I’m seeing lots of bluebirds these days, they are proving to be very challenging to photograph! The one above cooperated by staying put for a little while, but his position in the available light left a lot to be desired. Still, I kind of like that thin crescent outline of light on his breast and belly.

sassafras blossoms

I’m paying more attention to the small grove of sassafras saplings. Right now there is a patch of pretty violets surrounding their trunks. By April other wildflowers will be blooming there.

We checked on the sandhills pyxie-moss and found it still blooming, in spite of all the grasses, pine needles and cones, and assorted leaves trying to cover it up.

Look who we caught making himself right at home in the birds’ tray feeder.

Who robbed the Woods —
The trusting Woods?
The unsuspecting Trees
Brought out their Burs and Mosses —
His fantasy to please —
He scanned their trinkets — curious —
He grasped — he bore away —
What will the solemn Hemlock —
What will the Fir tree — say?

sandhills pyxie-moss

Last year the sandhills pyxie-moss was blooming on January 28 and was still blooming on March 7. This year we saw only one flower on the clump on February 26, but finally, on this March 21 visit we found a full bloom! We will keep checking on it. You may remember that this miniature shrub is very rare and found only in a couple of North Carolina counties.

It seems reasonable to believe that the more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction of our race. Wonder and humility are wholesome emotions, and they do not exist side by side with a lust for destruction.

After enjoying this wonder-filled morning, a pleasant surprise was waiting for me at home in the evening. As I went to close the drapes in the living room I noticed a pretty mourning dove sitting on the edge of the birdbath on our deck. She was watching me. We made eye contact and we gazed at each other for the longest time. Tim finally went and got the camera and took this picture of her, still looking at me. Years ago, and shortly after my mother died, a pair of mourning doves used to keep me company in my garden while I was out there weeding it, but it’s been many years since I’ve had one make contact with me like this. I felt comforted.

Things have been pretty discouraging around here since Tim had his stents put in. Thankfully he seems to be doing well in cardio rehab. But my dear sister has been diagnosed with the same kind of endometrial cancer I had back in 2017, and her prognosis may not be as favorable as mine was. Also, due to osteoporosis I’ve had to give up my beloved yoga practice. I’ve replaced it with tai chi, which I am liking well enough, but I still find myself grieving for yet another loss. I was very grateful for the solace the mourning dove was offering me.
