. We have jurisdiction pursuant to 28 U.S.C. § 1291 , and we reverse

. 1 “We review de novo the district court's dismissal of an action, accepting all factual allegations in the complaint as true and drawing ‘all reasonable inferences in favor of the nonmoving party. ’” Gregg v. Haw aii , Dep't of Pub. Safety , 870 F.3d 883,
886

– 87 (9th Cir. 2017) (quoting TwoRivers v. Lewis , 174 F.3d 987, 991 (9th Cir. 1999) ) (internal citation omitted ). Because the parties are familiar with the facts, we recite only those necessary to resolve the issues on appeal. Johnson alleges he was treated by App ellee J. Chudy,
M.D. in 2009 for urological symptoms. He was diagnosed with prostate cancer in 2013 and filed this action in 2014. The district court dismissed Johnson ’s claim as barred by California’s four

- year statute of limitations , finding the claim accrued in 2009 when Johnson sought medical care and was aware that his symptoms were not treated. On appeal, Johnson , represented by appointed pro bono counsel, argues that the district court erred in failing to apply the discovery rule of accrual and di smissing his action , without leave to amend, as untimely

. 1. The d istrict court erred in failing to apply the discovery rule and dismissing Johnson’s § 1983 deliberate indifference claim as time barred

. “Although courts look to state law for the length of the limitations period, the time at which a § 1983

1 Appellee J. Chudy, M.D. moves for judicial notice of Johnson’s amended complaint in another case

. We grant the motion and have considered the evidence. See Headwaters, Inc. v. U.S. Forest Serv. , 399 F.3d 1047, 1051 n.3 (9th Cir . 2005).3 17

claim accrues ‘is a question of federal law,’ ‘conforming in general to common

- law
tor t principles.’” McDonough v. Smith , 139 S. Ct. 2149, 2155 (2019) (quoting Wallace v. Kato , 549 U.S. 384, 388 (2007) )

. “Under federal law, a claim accrues when the plaintiff knows or has reason to know of the injury which is the basis of the action.” TwoRivers , 174 F.3d at 991

. Contrary to the district court’s asserti on, there are not two tracks for determining accrual dates in § 1983 cases. We apply the discovery rule in § 1983 actions of this nature. See, e.g. , Gregg , 870 F.3d at 885 (finding an Eighth Amendment deliberate indifference claim accrued when plaintiff knew, or had reason to know, through reasonable diligence, that her psychological injuries were caused by defendants ’ improper conduct in therapy) ; Bibeau v. Pac. Nw. Research Found. Inc. , 188 F.3d 1105, 1108 (9th Cir. 1999), opinion amended on denial of reh'g , 208 F.3d 831 (9th Cir. 2000) (applying discovery rule in an Eighth Amendment action involving experimental testicular irradiation experiments in prison)

. The district court’ s reliance on Wallace wa s misplaced because n either constructive notice nor the discovery rule was at issue in that case

. The victim of a Fourth Amendment false arrest is charged with actual knowledge

— he knows that he is innocent and that he has been arrested. See Wa l lace , 549 U.S. at 390 n.3 (stating the petitioner “was injured and suffered damages at the moment of his arrest, and was entitled to bring suit at that time” ).4 17

In contrast, Johnson alleges he suffered a latent or hidden injury and h is E ighth Amendment claim is governed by the discovery rule

. The injury that is the basis of Johnson’s claim is his development of advanced cancer as the alleged result of the defendant’s failure to treat him, not the symptoms and pain the defendant allegedly failed to treat in 2009. Based on his allegation s , h e could not have filed an E i ghth Amendment claim for failure to treat cancer in 2009. Though Johnson alleges awareness of his symptoms, he had no reason to connect the symptoms to cancer at
any time prior to his diagnosis in 2013

. It was therefore error for the district court to dismiss Johnson’s action on the ground of the statute of limitations. In light of this disposition, we need not address Johnson’s assertion that issues of fact preclude dismissal or his assertion of error in the district court’s denial of leave to amend.

. Because the defendant raises the supervisory liability argument for the first time on appeal, we do not address it.
