A cancer influencer who initially ignored her symptoms has tragically died at 31.

The influencer was young and healthy before she was diagnosed with the disease.

She then chronicled her journey on social media as she bravely battled the cancer head-on.

Letícia Siqueira Oliveira’s passing was announced by a friend in a video to her hundreds of thousands of followers on 17 March.

“Last October, when Lê started stepping away from social media, just before that high-risk surgery, she asked me that if this happened, I should take her phone and make this video,” the friend recalled through tears.

“I never thought this day would come, but it has.”

Letícia was 28 when she first experienced a sudden urge to have a bowel movement – but when she got to the bathroom, nothing came out.

She assumed it might be food intolerance or stress.

With so much going on in her life – her master’s degree, home renovations, buying a flat, and wedding plans – she ignored her body’s warning signs.

For at least five months, she tried to manage the symptoms herself with probiotics, medications, and dietary adjustments.

Young, healthy, and with no prior medical history, she never imagined it could be something serious.

It was only when more obvious signs appeared – abdominal bloating, pain, and traces of blood in her stool – that she began to consider an intestinal problem.

Even then, she delayed seeing a doctor, as reported by Need To Know.

When she finally sought medical attention, doctors discovered a tumor in her intestine at an advanced stage, with metastases in her ovaries and peritoneum.

Letícia underwent extensive surgery – including removal of part of her intestine, reproductive organs, and lymph nodes – and began chemotherapy, using a colostomy bag during recovery.

In March last year, she shared an “open letter to my stoma”, writing: “If there was a moment when I truly realised the gravity of everything, it was when I woke up with a piece of my intestine exposed – a huge cut, a drain, some organs, and several kilos lighter.

“That’s when I lost any innocence about what I was living through. That’s when I understood my life could be hanging by a thread. And ironically, it was also at that moment that I was reborn.

“The stoma forced me to learn from scratch something we’re all born programmed to do without thinking, without worrying.

“Ah, stomas, you’ve made me furious many times over these 16 months, but I can’t deny that you’ve taught me that I can live well and happily, even being different.”

Letícia – a physiotherapist from Santo Antônio da Platina, Brazil – was already a palliative patient at 30.

After marrying her fiancé in March last year, she told local media: “I am fully aware of my situation, but I also have a thirst for life.

“Today, I say yes to everything: trips, outings, concerts, friends’ invitations. We can’t live just for treatment.”

Her friend paid tribute: “I want to tell you that Lê never gave up, that she stayed strong until the end – the strongest person I have ever known.”
