Through Mo Shaoping, one of Liu's lawyers, the South China Morning Post has learned that the famous dissident's brother, Liu Xiaoxuan, has said that his 61-year-old brother was diagnosed with "terminal liver cancer" back on May 23rd. "Just as those captured in the 709 (crackdown) "met with high blood pressure", we suspect Mr Liu Xiaobo "met with liver cancer", and call for an independent third party medical organization to be involved", she said on Twitter.
It is unclear if Liu Xia, who reportedly suffers from depression due to her isolation, knows that her husband has terminal cancer or if she will be permitted to see him while he's receiving treatment.
Liu Xiaobo, a writer and a democracy campaigner, was jailed in 2009 for "subversion" after spearheading a bold petition for democratic reforms in China. The award was presented to an empty chair, which later became a symbol of China's repression.
Supporters demanded that Liu be granted the best medical care and criticised his treatment so far.
A Foreign Ministry spokesman said he had no information about Liu Xiaobo's situation.
The committee called for his unconditional release and said he should be offered the best possible treatment in China or overseas.
Liu has been honoured by Human Rights Watch, Reporters Without Borders and other rights groups.
"The campaign to establish universal human rights also in China is being waged by many Chinese, both in China itself and overseas".
Liu, who was jailed over his calls for greater democracy in China, did not plan to seek treatment overseas, Mo said. On December 25, after a trial that did not meet minimum worldwide standards of due process, Liu was sentenced to 11 years in prison.
China strongly condemned the prize as foreign interference in its internal affairs.
In response to the award, China suspended ties with Norway and froze free-trade talks, hurting sales of Norwegian salmon in the world's most populous country.
"It is unconscionable that the government neglected Dr. Liu's health, despite repeated calls from the worldwide community to ensure proper care".
Pro-democracy demonstrators hold up photo of jailed Chinese Nobel Peace Prize laureate Liu Xiaobo during a protest to urge for the release of Liu, who was sentenced to imprisonment seven years ago on Christmas day, outside the Chinese liaison office in Hong Kong, China December 25, 2016.
"The authorities must also stop their shameful and illegal house arrest of Liu Xiaobo's wife, Liu Xia, and ensure that she is able to receive visitors, travel freely and reunite with Liu Xiaobo".
"He can't undergo surgery, or do chemotherapy or radiation therapy", she says in tears.
In 1989, thousands of Chinese students and protestors demonstrated for weeks in Tiananmen Square calling for democratic reform.
