I've been taking advantage of the library's willingness to send books I request from any branch in the system to my home library, and have gone off on tangents exploring cults, politics, autobiographies, evolution, and minimalism. I love walking into the library and walking out with the latest stack they are holding for me behind the counter.
But it's not all serious non-fiction, I've also read novel after novel after novel. Some silly, some gripping, all helping me pass the time. Most all, anyway - once in a while I get a chapter in and decide I'm not enjoying the book enough to continue. No matter, there's always another in the queue. So here we are at the end of October, and I just finished my 94th book for the year. I have another week of time off work for my next chemo round and later, ten days off following my scheduled ankle surgery - I think I will easily be able to hit double my original goal by year's end.

My own particular chemotherapy regimen is just two chemo agents once the pre-medications (antiemetics, corticosteroids, anxiolytics) are in. When I first told my younger son I'd be on Cytoxan and Taxotere he said, "Wow. Kind of scary when they include the word 'toxin' in the drug." Cytoxan is a trade name for cyclophosphamide and was named because it's a cytotoxic drug. Cells go through a cycle of growing, dividing (mitosis), resting, and then starting over again. Normally, cells know when to stop that silliness, but not cancerous cells. They are marked by out-of-control growth, rapidly cycling through the phases over and over again. That's where chemotherapy comes in. Cyclophosamides are alkylating agents that alter the cell's DNA and slow cell growth. They act on cancer cells particularly during their resting phase, leaving them unable to replicate. The more rapidly a cell divides, the more useful a chemo agent is. The downside, of course, is that they also go after other rapid-growth cells like those in bone marrow, hair follicles and the mucous membranes of the mouth and gut. Yay.
Anyway, there is an interesting history behind the development of these drugs that goes back to World War I and the use of the first chemical weapon, mustard gas, by the Germans. It was nasty stuff, able to be absorbed through the skin so that gas masks weren't adequate protection. The troops hit by sulfurous clouds of mustard gas liquid would, at high enough doses, become blind and develop ulcerating necrosis of the skin. If inhaled, hemorrhagic pulmonary edema developed. As you can imagine, death from mustard gas was a miserable affair. The soldiers who didn't die went on to experience nausea and vomiting, hair loss and suppressed immune systems. Sound familiar?
So during WWII, Nazis again used mustard gas. Because screw the Geneva Convention prohibiting chemical warfare. A couple of pharmacologists thought, "Hey, if this stuff can kill people, maybe we should use it to fight cancer!" You can't make this shit up. And it did work, to an extent. Unfortunately, it was also near-lethal and only temporarily effective. But chemotherapy was born and nitrogen mustards like the Cytoxan being infused into me every three weeks are still being used.
