JERRY CHAVEZ, Jr. vs. CITY OF VERNON

This case concerns a police officer diagnosed with renal cell carcinoma who sought workers' compensation benefits under Labor Code section 3212.1's cancer presumption. The applicant presented evidence of industrial exposure to known carcinogens such as diesel exhaust and benzene. The defense failed to rebut the presumption by failing to present evidence that the primary cancer site was identified and that the identified carcinogen was not reasonably linked to the cancer. The Appeals Board affirmed the judge's findings, denying the defendant's petition for reconsideration.

Kevin Couch vs. COUNTY OF RIVERSIDE

This case involves a deputy sheriff diagnosed with chronic lymphocytic leukemia (CLL) who sought workers' compensation benefits. The Workers' Compensation Appeals Board (WCAB) granted reconsideration and found the applicant's CLL to be industrially caused. The WCAB determined that the applicant was entitled to the presumption of compensability under Labor Code section 3212.1 due to his documented exposure to benzene, a known carcinogen in gasoline and diesel exhaust. The Board concluded that the defendant failed to rebut this presumption, despite evidence suggesting an alternative cause, because they did not demonstrate by substantial evidence that the carcinogen was not reasonably linked to the applicant's condition. Therefore, the WCAB rescinded the prior decision and issued a new finding of injury.

ROBIN SMITH vs. CITY OF SUNNYVALE

This case involves a firefighter claiming breast cancer arose from employment exposure to carcinogens, triggering a statutory presumption of industrial causation under Labor Code section 3212.1. The employer sought to rebut this presumption by arguing a medical examiner found no studies linking applicant's specific exposures to breast cancer. However, the Appeals Board denied reconsideration, affirming that the employer failed to prove there is *no reasonable link* between workplace carcinogen exposure and the applicant's cancer, a higher bar than simply the absence of direct scientific studies. The Board reiterated that an employer must affirmatively demonstrate a lack of reasonable connection, not just highlight a lack of studies supporting causation.

SETH FRANKLIN vs. CITY OF REDLANDS, ADMINSURE

Applicant Seth Franklin, a police officer, sought reconsideration of a WCJ's decision that denied his claim for industrial injury in the form of melanoma. The WCJ initially found applicant was not entitled to the cancer presumption under Labor Code section 3212.1. The Appeals Board granted reconsideration, concluding that the WCJ erred. The Board determined that applicant, as a police officer, was exposed to solar radiation (a known carcinogen) and his melanoma developed or manifested during his employment, thus entitling him to the cancer presumption. The case has been returned to the trial level for further proceedings to determine if the presumption can be rebutted.

DANIEL BIGELOW vs. CITY OF PASO ROBLES

This Workers' Compensation Appeals Board decision reverses a prior ruling and finds applicant's colon cancer industrially caused. The employer failed to rebut the Labor Code section 3212.1 presumption of industrial causation for peace officers exposed to carcinogens. The Appeals Board determined the defendant's medical expert did not sufficiently prove the cancer was "not reasonably linked" to the applicant's workplace exposure. Therefore, the presumption stands, and the case is returned for further proceedings.

STEVEN JUDD vs. CITY OF DESERT HOT SPRINGS, CORVEL CORVEL CORPORATIONS

This case concerns Steven Judd's workers' compensation claim for kidney cancer. The Appeals Board affirmed the finding that Judd sustained an industrial injury as a peace officer, granting him the presumption of compensability under Labor Code section 3212.1. The Board found the cancer developed during his employment, satisfying the statute's requirements even though it manifested later. The defendant failed to rebut the presumption by proving no reasonable link between the carcinogens Judd was exposed to and his cancer.

DAVID GREGOR vs. CITY OF HAWTHORNE, Permissibly Self-Insured By ADMINSURE

The Workers' Compensation Appeals Board denied a lien claimant's petition for reconsideration, upholding a prior decision that disallowed the lien. The WCJ found the lien claimant failed to prove treatment was for an industrial injury and that the defendant successfully rebutted the statutory presumption of industrial causation for the applicant's cancer. The Board agreed that the lien claimant did not present substantial evidence of exposure to a known carcinogen, which is required to invoke the presumption. Therefore, the lien claimant failed to meet its burden of proof for industrial causation of the cancer.

LADONNA PALEGA vs. CALIFORNIA HIGHWAY PATROL, STATE COMPENSATION INSURANCE FUND

This case concerns a California Highway Patrol officer diagnosed with adenocarcinoma in situ of the cervix. The defendant, California Highway Patrol, sought reconsideration of a finding that this condition constituted an industrial injury under Labor Code section 3212.1. The defendant argued that the applicant's condition was not considered "cancer" and therefore the statutory presumption of industrial causation did not apply. The Workers' Compensation Appeals Board denied reconsideration, upholding the finding based on qualified medical evaluator Dr. Ngo's opinion that adenocarcinoma in situ qualifies as cancer under the statute. The Board found the defendant failed to rebut the presumption by providing evidence that the exposure to carcinogens was not linked to the disabling cancer.

SANDY BASTIAN vs. COUNTY OF VENTURA

This case involves a firefighter diagnosed with breast cancer who claimed industrial injury under California Labor Code section 3212.1. The defendant employer argued the statutory presumption of industrial causation was rebutted by an Agreed Medical Examiner's opinion stating the cancer was non-industrial, citing a lack of studies linking female firefighter exposures to breast cancer. The Appeals Board affirmed the WCJ's decision, finding the applicant sufficiently demonstrated exposure to carcinogens and the defendant failed to meet its burden to prove the exposure was "not reasonably linked" to the cancer. The court clarified that the mere absence of specific epidemiological studies does not rebut the presumption under section 3212.1.

GLEN HODGES vs. STATE OF CALIFORNIA

This case concerns a firefighter's claim for melanoma under Labor Code section 3212.1, which presumes cancer is industrially caused. While the applicant raised the presumption through evidence of carcinogen exposure, the Appeals Board overturned the initial finding of industrial injury due to melanoma. The Board found the presumption was rebutted by expert medical opinion concluding the applicant's melanoma was not reasonably linked to industrial sun exposure, citing significant childhood sun exposure, tanning bed use, family history, and minimal workplace sun exposure to the affected area. The Board therefore granted reconsideration and amended the decision to exclude melanoma as an industrial injury, though actinic keratosis was still found to be industrially caused.
