Parasite actress Park So Dam is battling cancer. 

The South Korean star—who played sister Ki Jung in the Oscar-winning film—was diagnosed with papillary thyroid cancer, her agency, ArtistCompany, told CNN on Monday, Dec. 13. The company added that Park, 30, received the news during a health checkup and has already gone through surgery.

Park was getting ready to promote her next movie Special Delivery, but her illness changed her plans and left her "very disappointed," per the statement.

"Park So Dam will focus on her recovery so that she can see you all healthy in the future, and ArtistCompany will also do our best to help the actor recover her health," the statement said. The message also thanked her co-stars and the crew for "overcoming this difficult time together."

According to the American Cancer Society, the type of cancer starts in the thyroid gland, which creates hormones that affect a person's metabolism, body temperature, heart rate and blood pressure.

"Thyroid cancer is commonly diagnosed at a younger age than most other adult cancers. And women are three times more likely to develop thyroid cancer than men," per the organization's website. "Most thyroid cancers can be treated successfully."

At the 2020 Oscars, Parasite took home the trophies for Best Picture, Best Director, Best Original Screenplay and Best International Feature Film.

Park has also starred in the series Record of Youth and movies Bakugan: Battle Force and Wooparoo Adventure. She recently attended the Busan International Film Festival in South Korea in October.
