I found the second one in the shower. A lump, higher up on the same calf, five years after the first. I knew before anyone told me, the way you know the second time, because you’ve felt what a stranger’s stunned face can mean and you don’t get to be naive about it again. The dermatologist did another biopsy. Then came the call. Cancer, again.

The first time, at twenty-five, I hadn’t grasped what was happening. This time I grasped all of it. And it was so much scarier for the knowing. There was a stretch of waiting that I wouldn’t wish on anyone, weeks of it, because insurance had to be argued with before I could get a PET scan. So I sat in the not-knowing, imagining it everywhere in my body, while paperwork moved at its own indifferent pace. When the scan finally happened, it showed nothing beyond the one spot, which was the best news available in a situation with no good news. But first there would be surgery.

They took lymph nodes from my groin. They took another large chunk out of my calf, above the crater the first surgery had left. They warned me I might need a skin graft, and in the end they didn’t do one, they just stapled what they could and left the rest of it open, wide open, to heal the slow way. The surgery ran long. My family sat in a waiting room getting more anxious by the hour, and afterward the surgeon actually apologized for how long it had taken.

Then, the next day, I started vomiting. Violently, endlessly, until I ended up in the emergency room. It was only later that the surgeon explained she’d pumped me full of antibiotics during the operation and that the vomiting was probably my system clearing the drugs out. I would have loved that heads-up in advance. A small thing, maybe, but when you’re a young mother throwing up in an ER a day after cancer surgery, a little warning goes a long way.

I had three children. My son was five. My daughters were three and one. I could not walk freely. I had a wound in my leg held together with staples and left partly open, and three babies who needed to be carried and fed and watched and loved, and I physically could not do it. Their father was not much help, not in the way that mattered. And the surgery wasn’t even the end of it. There was radiation still ahead of me, a whole further journey of treatment waiting on the other side of the recovery I hadn’t even gotten through yet. I was a very sick young mother of three who couldn’t stand on her own leg, with more still coming, and something had to give, and the thing that kept it all from collapsing was my mom.

My parents lived closer to Stanford, so I recovered at their house. But that’s the geography of it, not the truth of it. The truth of it is that my mother decided she was going to carry me through this, and she did. She’d sent me an email, at some point, saying she was insisting on being there through everything. And she was. Through everything.

I don’t remember the specifics the way you’d think I would. What I remember is her presence. Her being in the room. Her calling the doctor when I couldn’t stop throwing up. Her simply being there, steady, at every point where I would otherwise have been alone and terrified with a body that had stopped working and three small children I couldn’t lift. I didn’t have to ask. She was already there. She saved us. I mean that as truthfully as I’ve ever meant anything. She saved us.

There’s one hard thing threaded through this that I’ve had to make my peace with. Not everyone thought she should give so much. There was resistance to how completely she showed up for me, and I learned later that it came in part from my own sister. My dad helped. But when I’m honest about who carried it, it was her and me. Mostly her. And she did it over other people’s objections, because that’s who she was. She looked at her sick daughter and three tiny grandchildren and she did not hesitate, and no one’s opinion was going to move her off it.

I did one thing during all of this that tells you something about how I survive. I refused to know my staging. When they talked about it, I didn’t take in the number. I didn’t want it. I didn’t want a statistic living in my head, telling me my odds, coloring how I looked at my own children. I wanted to stay positive, and staying positive required not knowing certain things, so I didn’t let myself know them. I only found out my stage much later, and entirely by accident, long after it could frighten me. I’ve never regretted the not-knowing. It was how I kept walking toward the light instead of counting the dark.

We had no idea, that year, what the next one held. We didn’t know that within about a year it would be my mother in the hospital bed, my mother with cancer, my mother running out of time. She poured herself into saving me during what turned out to be one of the last years she had. She spent that irreplaceable period of her life nursing her daughter, and she did it gladly, and she never knew how little of her own time was left.

I carry guilt about that. I’d be lying if I said I didn’t. The guilt of having needed so much from her, right before she needed everything from us. The guilt of not knowing to save her the way she was saving me.

But I’ve had to hold that guilt up to the light and be honest about it, and here is what’s true. I could not have known. Nobody could have. And I could not have survived that year without her, not with three babies and a leg and body that wouldn’t hold me and no one else stepping in. Needing my mother when I was a young mother with cancer is not a debt I should be paying interest on for the rest of my life. It’s what she wanted to be. She insisted on it. She looked at the whole impossible situation and chose, over and over, to be the one who carried it. Now I’m sure she would have liked help but also she was so gloriously happy when my scan near the end of my treatments was clear.

So I’m trying to trade the guilt for gratitude, which is what she’d want, and which is truer anyway. My mother saved us in one of her last good years, and gave it without a second thought, and I didn’t know it was one of her last, and I would give almost anything to have known. But I don’t think she’d want me spending the rest of my life sorry that she got to be my mom when I needed her most.

She saved us. That’s the fact at the center of it. Everything else is just me learning to let it be a gift instead of a debt.
