Cancer Crawl 5 Feb 2025
Erratum: there was a 4th option I failed to mention on Thursday which is a sort of radiotherapy whack-a-mole where they radiate lesions as they start to cause symptoms. We’re not considering this one (for one thing, that’s a potentially infinite number of radiation treatments) so I’m not saying much more.

So, we are 99% sure I’m going with whole brain radiation. Just waiting for one bit of confirmation. Everyone says it’s my choice — ie, “I” am choosing it. But of course it’s not that simple when there are people close to you and medical experts weighing in.
When I last wrote, I was only a few hours from getting the news about the mets in my brain. There were conversations to have with medical professionals and family, and I needed time to think it through. This is not my first brush with cancer and the possibility of life-altering side-effects–I almost wound up losing my voice in 2009–but things feel different now than they have in the past. The cancer is more aggressive, and while I am usually a “bet on yourself” kind of person, I would say that December 2023-present has not been a very “lucky” period for my health between the concussion, the two hospitalizations for the cancer in my lungs this fall, and now this. I am still going to bet on myself, but cancer has a hand to play as well.
After some reflection, the options are more straightforward than they were initially. I do not have “get out of jail free” card: there are only choices that come with side effects and a potential for a decreased quality of life. The advantage of whole brain radiation is that it attacks all the mets. It is also the best bet for the shorter and longer term. The MRI report from last week mentions 17 mets. Some are new, and the older ones have doubled in size in the space of 6 weeks. The radiation would attack all of them including ones we don’t know about. And it would happen fast: better to get the tumour before more symptoms or bleeding shows up. (Bleeding with effects on me would mean brain surgery.)
Still, whole brain radiation is the first of a different class of cancer treatment I will have had. Up to this point everything I have had done has been specific and targeted. Modern treatments aimed at specific mutations, surgeries aimed at specific tumours or lesions, etc. Whole brain radiation is more, well, medieval. (There is probably a better word, but it’s my placeholder for “the cure is also the poison.”) Like old fashioned chemo, it aims at the whole organ or area. In attacking the cancer, it attacks the whole organ.
Part of this is because research hasn’t found any better options, at least not yet. Part of this is the blood-brain barrier. Presumably the cancer in my brain is the same mutation as the cancer in my lungs, but the drugs that are helping my lungs can’t get to my brain. So you attack the whole brain.
When you attack your whole brain with radiation, there is a good deal of potential for side effects down the road. Most of these surface months or even years after the treatment but they can be serious. Most of them sound like the accelerated effects of aging: slower recall, reduced verbal memory, hearing loss, cataracts, possible balance issues, emotional self-regulation, and on and on. I asked about musical memory (which is often the last to go) and of course there’s no research on that because this is a rare form of cancer and medical researchers don’t care about music (I KID but only a little). As a 54-year old in decent health otherwise my odds are good that the effects will be milder. But as with all side-effects, it’s a menu, you don’t get all of them, it’s chef’s choice what you do get and there’s no ordering off the menu. As an intellectual, I may also be more sensitive to changes in my cognition. I will say that everyone I’ve told this to in my age range immediate regales me with a story of a word they’ve forgotten, so if nothing else I get to mask it with middle age.
In the short term, side effects will be like other radiation treatments, which I’m used to. This is my third dance with external beam radiation. One small difference is my hair will fall out, but a little extra baldness for a few weeks won’t bother me. The fatigue doesn’t come on right away but it can be brutal; at least I’m off the lung meds while undergoing treatment so I have a chance at managing it. I’m guessing 2-3 weeks of fatigue. Carrie will be here to look after me. I might also have nausea and headaches. I’ve got drugs for that. Fatigue just takes sleep and time.
Friday I go in to sign a bunch of forms and get fitted for a mask, and have a practice run with the radiotherapy setup.

Unfortunately, this is not the end of this post. I have another announcement. Yesterday I went to see my Boston medical oncologist and learned that the cancer in my lungs has spread to my heart tissue. The treatment for that is an immunotherapy drug called Keytruda that’s taken in combination with dabrafenib and trametenib. The whole thing was a real surprise as I walked into the appointment thinking my brain was my problem and that the lungs were under control. As it turns out, you really have to read the report carefully to notice the word “aorta” as the word “heart” or “spread” never appears. Strike one point for medical jargon. We are waiting for the insurance company’s approval of the immunotherapy drug. I will write more about it in the coming days or week. This post is long enough.
Fuck cancer!
