Tukisa, the Last Hope for Breast Cancer Brain Metastasis Patients | Yubin's Desperate Petition

Tukisa Have you ever searched for the word?

 

Recently, among breast cancer patients, Tukeysa is not just a simple drug,
It is known as “the last hope for life.”

 

The effectiveness of Tukeysa as a treatment for breast cancer brain metastases is
This has already been proven clinically and through patient experience.

 

But the reality surrounding this drug is shocking in itself.

 

Yubin's Confession: The Pain of Breast Cancer and Brain Metastases Facing Her Family

 

In September 2025, Wonder Girls' Yubin revealed the story of her older sister suffering from brain metastasis from breast cancer through social media.

 

She said, “There is a treatment, but I can’t receive it because of the high cost of non-covered drugs,” and requested participation in the national petition called “Yubin Petition.”

 

That treatment is called Tucatinib, also known as Tukitsa.

 

This treatment is a new drug specifically designed for patients with HER2-positive breast cancer with brain metastases. It can deliver its effects to the brain, where existing treatments cannot reach, making it one of the few alternatives that can offer substantial survival benefits.

The problem, however, is that the cost of treatment is so high that it defies reality.

 

 

Tukisa received FDA approval, but... the reality is it's not covered by insurance.

 

Tukisa is a treatment that has already received approval from the Ministry of Food and Drug Safety in December 2023.

However, domestic sales have been indefinitely postponed, and patients must purchase the drug directly through overseas imports.

 

How much does it cost?

 

The cost of two months' worth of medication is approximately 30 million won.
Analysis has shown that if other anticancer drugs are used in combination, the annual cost will exceed approximately 200 million won.

 

Patients are suffering double and triple the pain as even drugs previously covered by insurance are now non-covered.

 

The reality is that only by using Tukeysa can one increase one's chances of survival, but the cost of treatment is causing people to give up on treatment.

 

Breast cancer: Brain metastases are scarier than early detection.

 

Many people say, 'Breast cancer is fine as long as it is detected early.'

But the actual patient experience is different.

 

Even after completing surgery, chemotherapy, and radiation therapy, breast cancer has the characteristic of metastasizing to the brain, lungs, liver, and bones, so patients who thought they had recovered from the disease end up having to fight it again.

 

 

Brain metastases have a particularly low survival rate,
It is a fatal metastatic site that drastically reduces the quality of life.

 

That is why Tukeysa, a treatment for breast cancer brain metastasis,
It is not an option for patients, it is a necessity.

 

The question raised by Yubin's petition: Why is life judged by its price tag?

 

Yubin said this in the petition:

“This isn’t just my family’s problem.
“This is an important issue for all breast cancer patients going forward.”

 

That's correct.

 

The reality that health insurance coverage standards determine life and death, and that access to treatment is determined by economic ability, must change immediately.

 

Yoobin's petition has been registered as a national petition, and if it receives more than 50,000 signatures within 30 days, discussion will begin at the National Assembly level.

 

Currently, more than 10,000 people have agreed.

The application of Tukisa's benefits is a matter of the right to life for society as a whole, not just for individual patients.

 

 

Tukisa: Not a choice, but a necessity… Now is the time to speak out.

 

'Tukisa' is a drug that opens up a possibility of survival for patients with breast cancer and brain metastases.

But now this drug is blocked in the face of reality.

 

tucatinib This drug, also known as , should be an accessible treatment for everyone, not a drug that people have to give up on because they can't afford.

 

Even at this very moment, countless patients are giving up when they have a cure right in front of them.

 

There's not much we can do, but
One petition, one voice
It can be a starting point for working together to protect life.
