Cancer

Cancer is presented at the climax as a condition Dan Torrance hopes to have escaped, not as a diagnosis the available scenes explain or confirm. After the True Knot is consumed by the lethal steam released from Concetta Reynolds, Dan is relieved of pain and hopes he is cancer-free; the uncertainty matters, because he cannot know for sure until he can look at his face in a mirror.

The condition and its uncertain status

The evidence does not establish when or how Dan’s cancer began, what kind it is, or whether a medical examination has confirmed it. At the decisive moment, cancer enters his thoughts as a feared condition that might have been removed along with his pain. His hope is real, but the text keeps it distinct from a verified cure: the mirror is still needed for confirmation.

That distinction leaves the condition suspended between bodily suffering and supernatural consequence. Dan can register immediate relief, yet he cannot translate that sensation into certainty about what has happened inside him. Cancer is therefore not resolved simply because the danger surrounding him has passed.

Pain, endurance, and uncertainty

Before the final confrontation, Dan answers concern about his condition by thinking of sluggish flies on his face and saying he will be all right for a while—long enough to check in and get an early start. His answer is deliberately provisional. He postpones any decision about what follows, invoking the practice of taking one day at a time rather than claiming a lasting recovery.

At the climax, the relief from pain changes the terms of that endurance but does not erase its limits. Dan hopes that he is cancer-free, yet he has no immediate means to verify it. The contrast between the flies he imagines on his face and the mirror he still needs makes bodily evidence central: what he feels offers hope, while confirmation remains out of reach.

Disease in the novel’s wider conflict

The True Knot’s crisis gives illness a separate, consequential role in the same plot. Bradley Trevor, an Iowa boy who had been an unusually perceptive baseball player, was feverish and had red spots before Barry approached him. Later, a member of the True Knot recognizes that the boy had spots and wonders whether measles had persisted in his steam and lain dormant. Nut considers the possibility that past immunity to childhood diseases may no longer protect the group and says that another case would require complete quarantine.

That danger becomes visible when Rose the Hat exposes red spots on Big Mo’s arm and tells the True Knot that the infection is among them. These scenes concern measles, not cancer, and do not explain Dan’s condition. Their juxtaposition nevertheless sharpens the story’s treatment of illness: an apparently invulnerable group can become susceptible, while Dan’s own hope of recovery remains unproven even after an extraordinary release of power.
