Twitch streamer HAchubby has confirmed she has been diagnosed with aggressive mature B-cell lymphoma, a fast-growing form of non-Hodgkin lymphoma that starts in B-cells, the white blood cells that help the body fight infection.
The South Korean creator, who is 36 or 37 and known professionally as HAchubby, shared the precise diagnosis on X on November 8, 2026. She said her stage and outlook remain unclear pending more tests at a hospital in Korea, but treatment is available. The cancer can spread quickly, which is why she traveled there urgently for care.
HAchubby first disclosed a cancer diagnosis live on stream around November 4-5, 2026, becoming emotional after receiving the results. She canceled plans to attend TwitchCon, gathered her medical records for transfer from her U.S. hospital, packed, and flew to South Korea. Upon arrival she said she had made it safely, planned to start treatment when the hospital opened the next day, and still attended the wedding of fellow streamer CharmingJo that evening to see friends. The hospital treating her is about four hours from the capital, which will limit visits. She has said she intends to continue streaming from Korea.
In updates reported by Dexerto, HAchubby described intermittent pain in one specific spot that began roughly three years earlier and usually faded after a few days. She had planned a full checkup before relocating to the Austin, Texas, area but completed only limited tests, something she later called a significant mistake. About four months before the diagnosis, around the time her father was diagnosed with leukemia, the pain intensified and lasted a full month.
Multiple hospitals turned her away because she was paying out of pocket. An urgent-care doctor initially suggested it was probably nothing serious. A later doctor referred her for one type of scan; the imaging center offered two. Fellow streamer QuQco, a Texas-area creator known for variety, IRL, painting and cooking content and a long-time collaborator, was with her and insisted she complete both. The second scan showed something wrong. A doctor called it serious and recommended a biopsy the same day. HAchubby agreed despite a $750 out-of-pocket cost and has credited QuQco’s insistence with saving her life.
HAchubby, who streams primarily under the handle @hachubbytv, has built an international following of more than 320,000 on Twitch and roughly 224,000 subscribers on YouTube through Just Chatting, IRL and travel broadcasts, music and piano streams, and collaborations. She began streaming in 2018 after losing a job at a lawyer’s office and while working at a convenience store. Early streams from the store helped her gain attention before privacy concerns arose. She deliberately learned English to reach a wider audience after starting with limited proficiency. She previously operated HAchuMart, a store in Busan that became part of her brand, and later moved to the United States, including the Austin area, after changes to Twitch’s service in South Korea, rebuilding her audience with IRL and travel content. Collaborators have included 39Daph, Nymn and QuQco.
Mature B-cell lymphomas are a group of non-Hodgkin lymphomas. Aggressive forms can grow and spread rapidly. Diagnosis typically relies on imaging, biopsy to examine cell architecture and markers, blood work and staging scans. Treatment often involves chemo-immunotherapy regimens such as R-CHOP or intensified variations depending on the exact subtype, stage, age and other factors. Many of these lymphomas are treatable, though individual outcomes depend on those details and how promptly care begins. Overall five-year relative survival figures for non-Hodgkin lymphoma are frequently cited in the mid-70 percent range in well-resourced settings, with better results for certain early-stage or responsive subtypes. HAchubby has emphasized that her stage is still unknown and that treatment is available while further tests proceed.
Support has already appeared from peers and the wider streaming community following her announcements. HAchubby has asked people not to worry excessively and has focused on the practical steps of records transfer, travel and beginning care in Korea while keeping the door open to continue connecting with her audience through streams.
