“New study links cancer patients and long Covid symptoms.
More than one in two cancer patients experienced symptoms of long Covid-19 for more than six months after initial infection.”

“COVID-19 virus could attack cancer cells and shrink tumors, new study suggests The early-stage research focused only on animal models, but scientists say it ‘offers hope’”
“SARS-COV-2 and cancer: So, what's the evidence, can SARS-COV-2 itself cause cancer, & separately can it increase risk & rapidity of death from existing cancers, & reactivate dormant cancers?
Let's start with what causes cancer 🧵”
“‘I’ve been in practice 23 years and have never seen anything like this,’ oncologist Kashyap Patel said.
Asutosh Gor, another oncologist, agreed: ‘We were all shaken.’
There was other weirdness, too: multiple patients contending w multiple types of cancer arising almost simultaneously, and more than a dozen new cases of other rare cancers…. The uptick in aggressive, late-stage cancers since the…pandemic is confirmed by early national data and a number of large cancer institutions.
Many…dismissed the trend as a consequence of disruptions to health care that began in 2020.
But not everyone.
The idea that some viruses can cause or accelerate cancer is hardly new… 15 to 20 percent of all cancers worldwide originate from infectious agents…”
“The correlation of COVID-19 and cancer poses significant challenges, as cancer patients are immunocompromised and more susceptible to viral infections. This dual burden has spurred extensive research to understand the correlation between the two diseases and to develop suitable therapeutic strategies. Reports have shown that SARS-CoV-2 proteins, such as the M protein, non-structural proteins, and spike protein, influence cellular functions relevant to cancer progression. These proteins can inhibit tumor suppressor genes, activate survival signaling pathways, stimulate cytokine production, and activate the NF-κB pathway, creating a tumorigenic environment. Additionally, SARS-CoV-2 proteins can promote metastasis by upregulating mesenchymal markers and metastasis-related signaling pathways. They have the ability to alter metabolic pathways, cause damage to DNA, and inhibit DNA repair systems, which can result in genomic instability and metabolic reprogramming that are specific to cancer cells. These viral proteins also influence programmed cell death evasion and aid immune evasion through upregulation of PD-L1 and M2 macrophage polarization. COVID-19 is further linked with epigenetic modifications induced by SARS-CoV-2, such as DNA methylation and histone deacetylation, that further may lead to changes in gene expression associated with cancer development. The activation of NLRP3 inflammasomes by SARS-CoV-2 intersects with multiple cancer hallmarks, suggesting a role in cancer development and progression.”
A close relative was diagnosed with a rare T cell lymphoma called Mycosis fungoides today. I wish I could adequately describe how many people I know with rare cancers at the moment.
I WHOLEHEARTEDLY believe—no, I KNOW—it’s a result of Covid.
A thread:
“My dad had a severe bout of COVID in March that caused hearing loss.
It caused other health issues that resulted in organ failure and his death. His oncologist believes it hastened the spread of his cancer too (dormant for years). In his words, ‘COVID is a cancer accelerant.’”
The risk of pancreatic adenocarcinoma following SARS-CoV family infection
“Our findings suggest the pancreatic adenocarcinoma as the most possible malignancy occurring after sever infection with SARS-CoV family.”
COVID-19 & Carcinogenesis:
The relationship between COVID-19 and cancer development is a complex interaction of immune suppression, chronic inflammation, genetic and epigenetic changes, and possible direct viral effects.
Disturbing trends: Rampant COVID-19 increases deaths from the pre-pandemic baseline.

“The Kralls are among a growing number of people who had COVID and then developed rare kinds of cancer, often more than one kind.
‘We started noticing some very unusual patterns,’ said the Kralls’ physician, Dr. Kashyap Patel. He and his colleagues at Carolina Blood and Cancer Care Associates have documented some very concerning links between COVID and cancer”
short answer: yes. Good breakdown from Hank Green, albeit a prudent analysis
