As The Plane Crashed Down — Well Isn't This Nice?

A Tragic Plane Crash in Brazil: Did We Lose Voices Who Could Have Advanced Cancer Research?

On August 9, 2024, Voepass Linhas Aéreas Flight 2283, an ATR-72 turboprop, crashed in Vinhedo, São Paulo, Brazil, killing all 62 people onboard. Among the victims were medical professionals, some tied to cancer care, heading to an oncology conference. A social media post on Telegram claimed eight cancer specialists died while researching links between mRNA vaccines and aggressive cancers, often called “turbo cancer.” This tragedy has sparked questions about the loss of expertise and whether these individuals could have explored critical vaccine safety issues. While some details remain unverified, their deaths prompt a vital question: Could their work have uncovered new insights into mRNA vaccines and cancer?

The Crash: What Happened

The Voepass flight, traveling from Cascavel, Paraná, to São Paulo’s Guarulhos airport, crashed in a residential area after a “flat spin” descent at around 1:21 PM local time. Brazil’s aviation authority, CENIPA, is investigating, with early reports suggesting ice buildup or de-icing system issues as possible factors. No official cause has been confirmed, and black box data indicates pilots noted the plane needed “more power” before the crash. The tragedy, the deadliest in Brazil since 2007, shocked the nation.

Medical Professionals and Others Lost in the Crash

A Telegram post claimed eight cancer specialists were among the victims, researching mRNA vaccines and “turbo cancer.” Below are the individuals named, with verified details where available and notes on unconfirmed roles, based on reports from the Paraná Medical Council, Uopeccan Cancer Hospital, and news outlets:

• Dr. Arianne Albuquerque Estevan Risso
  Role: Second-year clinical oncology resident at Uopeccan Cancer Hospital, Cascavel.
  Details: Dr. Risso managed ~20 cancer patients daily in the outpatient clinic and was traveling to the ONConexoes AZ conference to advance her ovarian cancer expertise.

• Dr. Mariana Comiran Belim
  Role: Third-year clinical oncology resident at Uopeccan Cancer Hospital, Cascavel.
  Details: Dr. Belim worked with a similar patient load and was attending the same AstraZeneca conference.

• Dr. Sarah Sella Langer
  Role: Pediatrician (unconfirmed as cancer researcher).
  Details: Named in the Telegram post and listed among victims by Voepass, but no evidence confirms oncology work. She was likely among the eight doctors noted by the Paraná Medical Council.

A Telegram post claimed all eight were cancer specialists researching mRNA vaccines, but only Risso, Belim, and Ferreira are confirmed as medical professionals with cancer-related roles. The others’ inclusion as researchers is unverified. Some reports misidentified victims, e.g., “Dr. Leo Ferreira” instead of Dr. José Roberto Leonel Ferreira. Source: PolitiFact

The Question of mRNA Vaccines and Cancer

A Telegram post suggested the victims were researching mRNA COVID-19 vaccines and “turbo cancer,” a term used online to describe aggressive cancers allegedly linked to vaccines, and were en route to present findings. No evidence supports this; the conference was ONConexoes AZ, focused on ovarian cancer, not vaccines. Source: Lead Stories

However, vaccine safety concerns persist. Dr. Ryan Cole, a pathologist, has argued mRNA vaccines may cause T-cell suppression, potentially affecting immune responses in cancer patients. His views are controversial and not widely accepted, but they resonate with those reporting rapid cancer progression post-vaccination. A 2024 study in Cureus found increased cancer mortality in Japan after mRNA boosters, particularly for ovarian and breast cancers, suggesting possible immune or hormonal effects. This study shows correlation, not causation, and delayed pandemic screenings likely contributed. Large-scale studies, like one of 100 million people, found no cancer link, but mRNA technology’s newness leaves questions open. [Sources: Cureus, 2024; 2024 Vaccine Safety Study]

Could These Doctors Have Found a “Smoking Gun”?

The loss of Drs. Risso, Belim, Ferreira, and others is a tragedy for their communities and medicine. Risso and Belim were immersed in oncology, while Ferreira’s radiology work aided diagnostics. Could they have explored vaccine-related immune effects, as Dr. Cole suggests? It’s possible, though unconfirmed, given the global debate. Seven other doctors scheduled for the flight survived by taking an earlier one, a poignant detail but not evidence of foul play.

Honoring Their Loss with Truth

This tragedy calls for clarity over speculation. Verified facts—eight medical professionals, including two oncology residents, died en route to a cancer conference—are heartbreaking. Unverified claims about mRNA research deserve consideration but lack evidence. We honor the victims by asking hard questions about cancer and vaccines, inspired by voices like Dr. Cole, while seeking verified data.

To learn more:

• Follow CENIPA’s investigation for crash updates.
• Contact Uopeccan Cancer Hospital about their oncology work.
• Support studies on long-term vaccine effects, balancing skepticism and evidence.

Let’s remember these professionals and push for answers in their absence.
