I dont think mangaka suffer from increased chances of brain tumor though.
Emilia Clarke had 2 aneurysms during the shooting of Game of Thrones, the first during the very first season, the second 2 years later. The facts she had 2 and survived both is already remarkable but the fact she was only 24/25 at the time of the first points out that sometimes these things happen to anyone regardless of age or any previous history.
Then you start factoring in comorbity from other parts of someone's life.
When the term "the silent killer" gets used it really should refer to aneurysms more as they can go undetected for far too long then pop and someone literally drops dead. Whether the rupture is induced externally from a head injury or simply happens after long enough will vary as the underlying condition can be that "dormant" nothing seems wrong for years despite the Damocles sword hanging no further than the lining of a blood vessel.
Take that, the highly overworked nature of manga writers/artists that is extremely evident in the more popular series and just how often new issues get put on break because the creator literally needs to stop before being hospitalised [again], and the equally destructive working environment of Japan where men are not only expected to work like this but then go and socialise and drink themselves to stupor all for the sake, pun intended, of conforming to what is meant to be the cultural working design of Japan, and you end up with a lot of Japanese men quite literally working themselves to death.
Even when this sort of behaviour only lasts a relatively short period of time in someone's life the damage caused by that time spent under these intense conditions and the various consumptions can start a countdown that may end up ticking for years or decades but still ends up stopping far sooner than it should have.
Like you said with the Clarke example, it can happen to anyone not necessarily a mangaka. That's why i don't think his death is related to his time as a full time mangaka over 30 years ago considering he had no other health problems that popped up from that lifestyle.
