Rachel, who shared her online battle with cancer, said that in her late teens, she felt like something was wrong but put it down to a gluten intolerance.
But she was directed to a specialist who found a 20cm tumour in her liver after seeing a doctor who understood her concern.
A biopsy then revealed Rachel had fibrolamellar hepatocellular carcinoma, an uncommon type of cancer that primarily strikes young, healthy individuals.
The condition is very rare, affecting only 200 persons worldwide each year.
The majority of cases involve teenagers and young adults, while patients as young as two and as elderly as 74 have been reported.
The majority of patients receive a late diagnosis since there are few warning signs, and by the time the illness reaches other body regions, it has already spread from the liver and becomes much more difficult to cure.
For stage 1 fibrolamellar carcinoma, the five-year survival rate is 86%.
But if the cancer advances to stage 2, the survival rate drops to 44%.
Rachel was taken in for surgery a few days later to have the tumour removed after being diagnosed with stage 4 fibrolamellar after noticing bloating in her abdomen.
She thought that this would be the last chapter in her cancer story, but it was only the beginning as three months later, the disease returned in her lungs and liver.
At this point, she said she "kicked into gear with research and healing."
The former college lacrosse player said that she had attempted every treatment available over the years, including both conventional and complementary therapies, to fight the illness.
After living in Los Angeles for a while, Rachel moved to New York in September last year, where her sister lives.
But in February of this year, just after making her big move, she suffered a serious health setback due to a lung haemorrhage.
Rachel explained in a TikTok video that the reason for this was that a tumour was pressing on her heart and obstructing her lung's ventilation, which is what caused it to bleed.
Her parents gave their approval for her to begin radiotherapy and immunotherapy to decrease the tumour and stop the bleeding, while she endured numerous life-saving emergency treatments and was intubated for three days.
Rachel then gave an update in June, saying she was figuring out her next steps after receiving scan results that showed some "very positive parts and some not so ideal parts."
Although most of the tumours on her body appeared "stable," physicians were concerned about one in her belly, so she decided to get proton therapy to cure it.
Proton beam therapy uses beams of protons to treat the tumour.
But unlie X-rays, they stop moving through healthy tissue as soon as they reach their target.
According to Rachel, she discovered that the proton therapy had fewer negative effects on her and had no effect on her daily activities.
