Summary
Cancer is back, somehow stronger, and White Blood Cell can't get out of his mind the last face-off he had with him. But this time its different, it seems it won't have to be the only thing they'll have to face. Death sorrounds them as they are caught in the crossfire between cancer and chemo, trying to keep each other alive is a battle in itself. In the midst of all this, will they be able to act on their feelings for each other? His duty is to protect this world, not HIS world, and its the first time he realizes that they are different concepts, and Cancer is hot on their heels, but he's battling his own demons as well.

Summary
1146 wasn't sure how he'd buried that memory so deep. An eye that refused to open when he was just a little stem cell.
He'd forgotten almost everything about his childhood as a myelocyte. He had no need to remember, up until now, and it did turn out that the things that filthy cancer cell had said to him were true.

Summary
"When this body watches those silly documentaries, you know what they always say? When cancer wins, it explores a little. What starts in the kidney can end in the brain, or what starts in the heart can grow in the intestines" Cancer hisses, a wicked smile on his face as he stares down at 1146. He can do nothing in that little tube of his.
"What do you think, friend...?"
The mutated cell dragged out the "friend" as if he was pulling it out of his mouth by a string.
"I think it'd be fun. Do you have any ideas?"
1146 says nothing, but Cancer's next sentence makes his jaw drop, eyes wide with horror.
"Oh, I know! Let's start with leukemia! Let's start with you."

Summary
This sequel tackles some unanswered questions about CC’s life between his third birth as a normal cell and the moment he makes Silver.
At the end of “Forgive, not Forget” I also hinted at a possible romantic relationship between CC and NT 4201 and I explore it in this fic. I can't help thinking that CC (as a normal cell) and NT 4201 would be a nice couple.

Forgive, Not Forget by Antinael
Fandoms: はたらく細胞 | Hataraku Saibou | Cells at Work! (Anime)

Summary
This fanfic is inspired by NeriHyuga’s fanfic “Umare Kawari Saibou: Cells reborn”, on AO3. The author of this wonderful fic had the idea of Cancer being reborn for the third time, but as a normal cell this time around. Her fanfic goes from that point on and mine is an exploration of the emotions Cancer might have felt, dealing with the normal cell life for the first time and with what might be a touchy subject: cell division.
How will his life be, when he has to do what every other cell does: make a copy of himself? A proper copy, one that is what he would have been, if he weren't defective.
In “Forgive, Not Forget” I tackle redemption, rehabilitation, friendship, wasted potential, the importance of living in a harmonious environment. I love “Cells at Work”, it is a beautiful anime!

Summary
!!Spoiler alert!! This fiction plays some time after the manga, so it can contain spoilers if you only know the anime adaption!
Part of the fiction:
- He slowly opened his eyes. Wetness crept in from the surrounding liquid. He was inside a machine, the dividing machine, that allowed a cell to copy itself.
He was a newborn, but in the same time a fully fledged cell. His eyes needed some time to adjust, but the liquid didn't hurt. Something was strange though. The room was dark and empty. It felt kind of cold.Story:
- Cancer is once again reborn, but not as a Cancer Cell this time, but as a normal, common cell with some little defects in appearance, but nothing malignant. He lost his memories and gets from one dangerous situation to another, but he is finally allowed to live. His former enemies now have to protect him.

Summary
Cancer Cell traps U-1146 again. Only this time, it's just the two of them.
U-1146 isn't sure that he's going to get out of this one. He isn't sure that the body is going to get out of this one. And if it's a choice between the two, he knows what's more important. But maybe there isn't any choice at all...
Cancer Cell wants to get to know his kind-hearted killer better. He wants a friend. Someone to really talk to. But he also wants revenge on a world that rejected him, control over the cells who could destroy him, and right now he has a helpless white blood cell, and a knife, and plenty of time...
...this isn't likely to end well for anyone.
(This is written for Bad Things Happen Bingo on tumblr and got much darker than I intended and also multi-chaptered somehow? Basically just me putting my fave through hell at the multiple hands of my other fave... please read the warnings! BTHB prompts so far: Biting, Muzzled, Hair Matted With Blood.)

Summary
This had all been a crazy idea to begin with. Abandon his post as a white blood cell, give up killing germs on a daily basis, to keep this one cell from destroying the body. Or, more to the point, to keep this one cell alive. Because White Blood Cell #1146 could say all he wanted that it was to protect the body, but if that were the case, he would have already killed this cancer cell.

Summary
“Mr. Dendritic, what type of cell is this?”
“That’s a cancer cell, they’re-“
“Why are they hurting him?”
“Because they’re dangerous. They don’t follow our rules, so they can’t stay here.”
“Oh… will I ever have to fight one of them?”
“I hope you don’t, but-“
The phone started ringing, the elder cell walking away to answer it. He returned shortly after, “Time for you to head back to the bone marrow, they want to start your training,
before you wake up.”
