OPINION
delivered the opinion of the court,
We granted review to determine when the statute of limitations begins to run in a workers’ compensation case in which the employee suffers from an occupational disease. The trial court dismissed Employee’s suit as untimely, reasoning that the statute of limitations began to run when Employee gave notice to Employer that she had an occupational disease. The Special Workers’ Compensation Appeals Panel affirmed the trial court’s judgment, relying upon
Bone v. Saturn Corp.,
I. Factual Background
In 1991, Shirley Brown (“Ms. Brown”) began working for Erachem Comilog, Inc. (“Erachem”), a manufacturer of electrolytic manganese dioxide, a black powder product used in dry-cell batteries. At Era-chem, she was continuously exposed to chemicals in the plant. In 1999, Ms. Brown was diagnosed with lung cancer. In February 2000, she was informed that her cancer was caused by exposure to chemicals at Erachem. She gave notice to Era-chem that she believed her cancer was caused by exposure to chemicals at work. Ms. Brown underwent surgery that same month, and a portion of her right lung was removed. As a result of the surgery, Ms. Brown missed work from February 14, 2000, through August 28, 2000. She returned to work at Erachem with no restrictions. Ms. Brown’s supervisor testified that Ms. Brown continued to do the same job that she had done prior to the surgery, that she did not ask for any special treatment or help, and that she was able to perform “her complete load.”
*921 Ms. Brown underwent further treatment and, as a result, missed more work from December 27, 2001, through March 19, 2002. She again returned to work. Unfortunately, her cancer recurred in the spring of 2002. She continued working for Erachem, however, until July 11, 2002. Ms. Brown filed for workers’ compensation benefits on April 7, 2003, and died from causes related to cancer on November 11, 2003. 1
Ms. Brown’s treating physician, Dr. Howard Bums, an oncologist, testified she was cancer-free following her surgery in 2000. He stated that after her surgery there was no disability associated with her cancer and that he expected her to recover fully and live a normal life. Dr. Burris testified that there was no evidence of a recurrence of cancer until the spring of 2002. He opined that the cause of the cancer was a combination of Ms. Brown’s smoking and her exposure to toxic chemicals at work.
The trial court dismissed Ms. Brown’s suit as untimely. The trial court reasoned that the statute of limitations began to run in February 2000 when Ms. Brown gave notice to Erachem that she had cancer and that it was work-related. The trial court therefore held that her suit was time-barred. The Special Workers’ Compensation Appeals Panel affirmed the trial court’s judgment, observing that “[ojccupa-tional disease cases are treated the same as gradually developing injuries for the purpose of determining when the statute of limitations commences.” The Panel relied upon
Bone v. Saturn Corp.,
II. Analysis
We review workers’ compensation cases de novo upon the record of the trial court, accompanied by a presumption that the finding of the trial court is correct, unless the evidence preponderates otherwise. Tenn.Code Ann. § 50-6-225(e)(2) (2005);
Layman v. Vanguard Contractors, Inc.,
When construing a statute, our primary purpose is to give effect to the legislative intent.
State v. Flemming,
*922
The Special Workers’ Compensation Appeals Panel in the instant case, citing
Smith v. Asarco, Inc.,
The statute of limitations in an occupational disease case is governed by Tennessee Code Annotated section 50-6-306(a) (2005),

which states, in pertinent part, that it begins to run “as of the date of the beginning of the incapacity for work resulting from an occupational disease.” In
Adams v. American Zinc Co.,
This Court has held that the “incapacity for work” resulting from an occupational disease begins when the employee knows or reasonably should know that she has an occupational disease and that it has injuriously affected her capacity to work to a degree amounting to a com-
*923
pensable disability.
Adams,
An “incapacity for work” also may occur when an employee’s occupational disease compels her to request a different position or when an employee is told by a doctor that she must stop working.
See, e.g., Bilyeu v. Sherwin Williams Co.,
No. M2001-01338-WC-R3-CV,
We are mindful that an employee may seek treatment for an occupational disease and may be absent for periods of time for that treatment. For the purpose of the statute of limitations, “the beginning of the incapacity for work resulting from an occupational disease” starts when the employee is unable to perform her regular employment duties, not from the date of treatment. “It is injury from the disease, rather than the disease, which entitles an employee to compensation.”
Adams,
This conclusion is consistent with the remedial policy of the Workers’ Compensation Law and the goal of maintaining an employee’s capacity to work by providing complete and early access to reasonable and necessary medical treatment.
See Moore v. Town of Collierville,
Ms. Brown was absent from work for treatment between February and August 2000. In August 2000, Ms. Brown returned without restrictions to the same position she had held prior to her absence. Despite periods of absence due to treatment, Dr. Burris testified that he believed that Ms. Brown was cancer-free following her surgery in 2000 and that her cancer did not progress to the point that it adversely affected her capacity to work until she stopped working for Erachem on July 11, 2002. Dr. Burris did not advise her to stop working prior to that date. Dr. Burris testified that Ms. Brown suffered no disability with regard to her cancer at the time she recovered from surgery and returned to work. Ms. Brown’s supervisor testified that Ms. Brown continued to do the same job she had done prior to the surgery, that she did not ask for any special treatment or help, and that she was able to perform “her complete load.” It was not until July 11, 2002, that Ms. Brown could no longer fulfill the responsibilities of her employment. Ms. Brown filed her workers’ compensation claim in April 2003. Accordingly, we hold that her claim was filed within the one-year statute of limitations period, which began on July 11, 2002, the date of “the beginning of the incapacity for work resulting from an occupational disease.” Tenn.Code Ann. § 50-6-306(a) (2005).
We disagree with the trial court and the Panel that Ms. Brown’s 2000 report to Erachem that she believed her injury was work-related started the running of the statute of limitations. Under Tennessee Code Annotated section 50-6-306(a), the statute of limitations for an occupational disease claim is not triggered by an employee’s notice of her injury if the injury has not yet become incapacitating. An occupational disease may manifest itself and produce symptoms years before the disease results in an actual incapacity to work.
See Adams,
Conclusion
We hold that Ms. Brown’s claim for benefits was timely. Accordingly, we reverse the trial court’s judgment that the statute of limitations bars her lawsuit and remand this case to the trial court for proceedings consistent with this opinion. Costs of this appeal are taxed to the appel-lee, Erachem Comilog, Inc., for which execution may issue if necessary.

. William Brown, Jr., Ms. Brown’s surviving spouse, became the named plaintiff in this case after Ms. Brown’s death.

Bone
in
Building Materials Corp. v. Britt,
. The statute of limitations for an occupational disease in effect at the time of the trial in this case was worded slightly differently. See Tenn.Code Ann. § 50-6-306(a) (2002). It states that the statute of limitations begins to run “after the beginning of the incapacity for work resulting from an occupational disease.” Id. (emphasis added). Because our analysis will not differ under either version of the statute, we have cited to the current version.
