ABOUT TTOBOM

TTOBOM means “spring again”

Korea’s first non-profit for young adults with cancer. In Korean, bom is both “spring” and “to see.” TTOBOM is spring returning — and seeing you again.

WHY TTOBOM

Cancer does not skip the young

In 2023, 20,253 people in their 20s and 30s were newly diagnosed with cancer in Korea — 55 every day.
Yet almost nothing existed for those who met cancer at the age they were meant to be starting out.

  • “It must run in the family”

    For people in their 20s and 30s, cancer far more often traces to environment — stress, diet, how they live — than to genes.

  • “They must have been frail”

    It arrives at the healthiest age too. It is nobody’s fault.

  • So they hide it

    Only at the hospital bed do visitors say quietly: “Actually, I had it too.”

  1. It is common

    55

    young adults diagnosed every day 20,253 in 2023 · up 20.5% in five years (20s)

  2. Most survive

    70.6%

    five-year survival rate Cancer is a disease people come through

  3. But they cannot return

    30.5%

    return to work within 5 years Europe is 62% — we are at half of that

What keeps them out is not the illness

69.5% faced discrimination at work
  • “They cannot contribute to society”72
  • “Cancer cannot be cured”58
  • “They cannot regain their health”57

Treatment ends, but life does not simply resume.
That is the time TTOBOM exists to protect.

RETHINK

All of us carried
assumptions about cancer

over90%

Young adults with cancer have no family history.

Not something in the family. Not a weak constitution. The cause is stress, diet — how we live. Which means this could be anyone’s story.

Analysis by a major university hospital in Korea

A change of perspective

In Korea, many employers give credit for completing military service. So why not for surviving something harder? Coming through cancer is not a liability — it is resilience already proven.

Saying it out loud

We want a society where people can name their cancer without flinching. Attitude alone will not get us there, so TTOBOM pushes for policy change — and in the meantime, builds places where people can simply enjoy themselves.

OUR STORY

Started by someone
who had been there

“Why is there nothing for us?” TTOBOM began with that one question.
2015

Stage 4 lymphoma, clear in five months

Lee Jung-hoon was diagnosed with stage 4 Burkitt lymphoma. A young body spreads disease fast — but it answers treatment just as fast. Five months after a terminal diagnosis, he was back in ordinary life.

What he learned

The body was the easier part

“Why me?” Self-denial was the real wall. What pulled him over it was a plan: “when this is done, I’m going there.” The will to recover needs something to hold on to.

2016

Passing it on

Visitors kept saying, quietly, “Actually, I had it too.” That is how much people were hiding. He gathered others who felt the same, and that community became a registered non-profit in 2020.

“Young adults with cancer are an iceberg.
What shows above the water is a fraction —
far more are hidden beneath it.”

THE NAME

TTO, BOM

One name, holding two meanings.

The first

To see again

“I SEE YOU.”

The greeting people exchange in Avatar.
In Korean, bom means exactly that — to see.
TTOBOM adds one thing.

I want to see you well again.

The second

The season that returns

“SPRING, AGAIN.”

However long the winter holds,
the season comes back around.
That is the promise in this name.

It will come back to you too.

I SEE U AGAIN — we see you again.

OUR MISSION

Four directions

So that ordinary life can bloom again.

Changing perceptions

From “why so young?” to assumed heredity to assumed fragility — we push back on all of it.

Emotional support

We connect peers walking the same road, so no one walks it alone.

Better care

We demand treatment environments that fit young patients.

Returning to life

Through treatment and out the other side, we walk with them back to daily life.
