Doctors insisted my pain was ‘just gas.’ Then I was diagnosed with cancer… a kitchen appliance had been slowly poisoning me for years
Schayene Silva was excited to finally move into her new home in February 2022.
But just a few months later, she began suffering from debilitating heartburn, coughing and vomiting.
Concerned, she visited a doctor who dismissed the pain as ‘just gas.’ But it didn’t go away. She spent close to three years bouncing between seven more doctors – all of whom also claimed the issue was digestion.
It wasn’t until the eighth doctor finally referred Silva, 38, for an MRI scan in October 2024 that the Oklahoma mom discovered the true terrifying cause of her pain: cancer.
The scan had revealed a mass on her left kidney that doctors determined was Stage 1 clear cell renal carcinoma (ccRCC) – the most common type of kidney cancer in the US.
While most kidney cancers have no clear cause, lifestyle habits like smoking and drinking alcohol can lead to DNA damage that causes the formation of tumors. When Silva explained to the doctors that she didn’t smoke or drink heavily, they told her the disease was just ‘bad luck.’
The mother-of-two had the tumor surgically removed in April 2025, but she was determined to find the root cause to keep it from coming back. After researching potential causes online, Silva decided to have her home tested for mold, which produces toxins linked to organ damage and some forms of cancer.
Initial testing came back clear until Silva thought to investigate her ice machine. After pulling the outer case apart, she discovered the machine was ‘covered in mold.’

Further testing revealed Silva had ten times the normal amount of Ochratoxin in her body, a toxin produced by Aspergillus (green) and Penicillium (blue) molds.
According to the World Health Organization, the most notable effect of Ochratoxin is kidney damage, but the toxin may also have effects on fetal development and on the immune system.
‘I started having this flank pain that wouldn’t go away, and that’s when I started going to the doctors,’ Silva said.
One doctor told her she ‘was too young to have cancer,’ she recalled, adding that ‘Nobody took me very seriously until someone sent me for an MRI and CT scan.’
Silva said she learned about her diagnosis ‘through the online portal,’ which said a mass was found on her kidneys.
‘All I could do was cry,’ she said. ‘It was really horrible. For weeks I was crying, but then I had to pick myself up. I started doing all the research I could.’
Kidney, also called renal, cancer strikes around 80,000 Americans every year and kills 15,000, making it the seventh-most common cancer in the US.
CcRCC, which starts in the cells that help filter waste out of the blood, makes up about eight in 10 kidney cancer cases.
The disease typically affects older Americans, with an average diagnosis age of 65. Only six percent of patients are aged between 35 and 44, according to the National Cancer Institute (NCI).
The exact causes are unclear, but a growing body of evidence suggests toxins produced by certain kinds of mold could raise the risk.

Mold typically takes just one to two days to begin growing in high-moisture areas like dishwashers and ice makers, though it can take weeks or months for more obvious signs like odors and visible stains to appear.
There are several types of mold that are more dangerous than others. The most severe form, black mold, produces dangerous chemical compounds called mycotoxins that, when inhaled repeatedly, cause cognitive impairment, mood changes, asthma-like symptoms, headaches, coughs, muscle aches and autoimmune responses.
When the body detects toxins, such as spores in the air, the immune system launches a massive defense, sending out a storm of inflammatory chemicals called cytokines that act like emergency alarms.
Inflammatory cytokines can travel throughout the body via the bloodstream and reach every organ system, including the endocrine system and the brain. Mold then triggers inflammation, damages tissues and attacks vital cells and neurons.
Silva’s testing, which is usually done with urine or blood tests, showed Ochratoxin A, a mycotoxin produced by green and blue molds. It is also considered a nephrotoxin, meaning it triggers inflammation and cell death in the kidneys, increasing the risk of cancer.

‘I was devastated,’ Silva said. ‘I have two little boys, [so] all I could think of was that I was going to die.
‘When I had my surgery, I was like, “What do you think caused it? There has to be one thing.” [The doctor] said they can’t really tell. He said, “It’s probably just bad luck.”
‘I wouldn’t accept bad luck. If there’s one thing I am, I’m very lucky.’
Silva is now cancer free after surgery and has stopped using her ice machine, which she said has alleviated symptoms like heartburn, nausea, hair loss and anxiety.
‘I haven’t had any panic attacks, I’m able to drive again, my hair is growing, my nails are growing,’ she said.
‘Once you’re out of exposure, your body knows how to heal. I knew [the doctor] was wrong, so I didn’t give up. I feel like I have beat it. I’m good.’
