Mariana Tata had always enjoyed a life marked by health and minimal worries.

Despite her anemia diagnosis, she felt invincible, as if nothing could disrupt her well-being.

However, in April 2024, she noticed her stomach was unusually bloated. Initially, she thought it was just a matter of gaining weight, constipation, or perhaps a food intolerance.

As the months passed, her stomach continued to swell while her appetite dwindled. “Even after eating just a small portion, I always felt completely full,” said Tata, who is now 27.

Before long, she also observed traces of blood in her stool, attributing it at first to her anemia or possibly hemorrhoids. “It wasn’t until the occurrences were more frequent that I started to worry,” she explained.

Working as an enrollment operations assistant, Tata found herself needing to miss work more often as her symptoms became increasingly severe.

She continued to dismiss her symptoms until May 2025 when, at the age of 26, Tata finally saw a doctor and got a series of blood tests, an abdominal ultrasound and a stool test. 

The tests revealed a 7in mass on her ovaries, which doctors later found was due to Stage 4 colon cancer that had spread to the ovaries and abdominal wall.

Mariana Tata was just 26 years old when she was diagnosed with Stage 4 colorectal cancer that had spread to her ovaries and abdominal wall 

‘I felt detached, as though I were outside my body,’ Tata said of the moment she received the news. ‘I was terrified and repeatedly thought that it couldn’t be real. 

‘I struggled to accept the diagnosis and wished the entire situation would simply disappear. At one point, I blamed myself, wondering whether I could have prevented it if I had paid close attention to my body.

‘But my greatest fear was that I was going to die.’

Tata is one of a growing number of young Americans affected by colorectal cancer (CRC).

Despite the disease decreasing by about 2.5 percent per year in people over 65, a recent report from the American Cancer Society (ACS) found incidence among adults under 50 – which is considered early-onset – has gone up by about three percent yearly.

In fact, 45 percent of CRC diagnoses are in people under 65 years old, according to ACS.

The ACS report also found three in four CRC patients under 50 are diagnosed at either regional or distant stage, which refers to either Stage 3 or 4.

Within that group, 27 percent are in Stage 4 at the time of diagnosis, like Tata.

According to ACS data, the five-year survival rate for localized colorectal cancer is 91 percent, which drops to 74 percent for regional cases. But in distant disease, the survival rate drops to 13 percent.

Another study also found CRC to be the leading cause of cancer death in Americans under 50.

For many young patients, such as Tata, CRC symptoms are subtle, like dabs of blood on toilet paper or abdominal pain, and in some cases, symptoms are even nonexistent, leading to later diagnoses and more advanced, harder-to-treat tumors.

Tata was forced to have both ovaries and her fallopian tubes removed, eliminating her ability to one day have children on her own. She also had a partial bowel resection before starting biweekly chemotherapy.

‘I was deeply upset for some time, but I was also grateful the tumor had been removed,’ Tata said. ‘I still struggle with the reality that I won’t be able to have children biologically.

‘At one time, I envisioned becoming a mom. However, that is no longer possible.’

Tata is still undergoing chemotherapy, but doctors believe her condition is stable. However, she may need additional surgeries in the future. 

For now, she’s thankful the cancer has stopped spreading, and she is looking toward the next few years with hope. 

She is also looking forward to returning to work, as the ‘financial burden remains significant.’

Now 27, Tata is urging other young people to seek medical help immediately if something feels off and to get a second opinion if they feel dismissed

‘Each day presents different emotional challenges,’ Tata said. ‘At times, it’s hard to accept that this is my reality. I sometimes wish it was a nightmare I could wake up from. 

‘I live with fear every day, though I choose not to let it define me.

‘My hope for the future is to simply be here – to watch my nieces and nephews grow up, to get married and to live a long, meaningful life.’

Tata is also urging other young people to advocate for themselves and seek a second opinion if they feel dismissed to avoid their disease spreading.

‘Don’t wait for symptoms to worsen. If something feels wrong, see your doctor,’ she said. 

‘This is not solely a disease of the older generations. Increasing numbers of young people are being diagnosed. You know your body better than anyone – listen to it.’
