The mum-of-one posted a TikTok which now has 2.3 million views, explaining all the warning signs that she dismissed, ‘assuming’ it was something less serious.
She is now urging people to ‘advocate for themselves’, after many find that they are told their symptoms are not cancer.
As she outlined the five main symptoms, she noted: “If you have any of these symptoms, please don’t be concerned, but go see a doctor.”
Changes in stool
One of the most common signs of colon cancer is changes in your bowel habits. And for Oda, it was the first subtle sign that she noticed.
Her stool appeared to be thin and pencil-like, but she brushed the symptom off as ‘constipation’.
She also noticed blood in her stool, but assumed that it was as a result of haemorrhoids.
However, in younger patients, a 2024 study highlighted blood in stool as one of two top ‘red flag’ symptoms.
She also noted feeling like her bowels were never fully empty.
In the video, she said: “Each time I would use the restroom, I would feel like I still needed to go. I would keep pushing and pushing but nothing would come out.”
Unexplained pain
While pain near the abdomen is a known symptom of colon cancer, pain that is felt elsewhere in the body could be a sign that the cancer has spread.
Oda felt pain on her right side near her breast.
She said: “I just assumed my bra was too tight, even though it was just on one side.”
In reality, her cancer had actually spread to her liver.
Chronic fatigue
Amid dealing with pain and changes in her stool, she was also chronically tired – no matter how much sleep she had.
She shared: “I would still need to take a nap a few times during the day and nothing really helped.”
Cancer causes fatigue as cancer cells use up all the body’s energy.
Other signs
In a separate video, she documented a couple of the less-known symptoms that she experienced leading up to her diagnosis.
These included weight loss, loss of appetite and constant stomach pains.
Up until doctors told her she had cancer, she blamed these symptoms on a ‘really bad stomach bug’.
If you experience any of these symptoms, it’s important to seek advice from a healthcare professional as soon as possible.
