illness

i came across this text [1]:

Be certain that all that appears is naturally manifest [in the mind],

Like the images in a mirror which [also] appear naturally.

[…]

There are no phenomena extraneous to those that originate from the mind.

so i asked myself: if a person has an illness, let’s say a tumor, is that caused by that person’s mind?

how does buddhism explain illness?

:: what is illness ::

our experience of the world, of the body, of the illness, are inseparable from the mental processes through which we perceive and interpret them.
