I sent you the links
The second link
you sent does not mention anything about the Chinese HIV-like virus causing cancer, but just talks about cancer in general.
The first link
(translated to English) says this:
After 5-7 years, some patients developed intestinal cancer or showed signs of intestinal cancer.
After 5-7 years, some patients developed or showed signs of lung cancer.
These seem imprecise statements. What does it mean to "show signs of lung cancer"? If someone is just speculating that they have lung cancer based on symptoms, that is not a reliable diagnosis.
I would not worry too much about this. First of all, there is no test for the Chinese HIV-like virus, so we cannot know for sure who has this virus. Other infections can cause similar symptoms, and there are likely many people who think they have the Chinese HIV-like virus, but may in fact have another infection. So all speculation about the Chinese HIV-like virus is a bit unreliable to begin with, because of the fact it is hard to know who has it.
Secondly, anecdotal reports in newspapers about patients getting cancer are no substitute for a proper epidemiological study. Cancer is very common, so naturally you are going to get a few people with the Chinese HIV-like virus getting cancer; but this may have happened anyway.
In the UK for example, there are 367,000 new cases of cancer every year. The UK has a population of about 67 million. Using that data, you can work out that over a 10 year period, in a group of 35 people, 2 will develop cancer, on average.
The virus I caught
, which was quite similar to the Chinese HIV-like virus, infected about 35 of my friends and family. Over a 10 year period, 2 people in this group infected with my virus developed cancer. But that is no higher than the UK national average, which suggests my virus is not promoting cancer.
