A twin family from Virginia stuck in Colorado after it turned out …

A family of eight from Virginia was captured in Colorado after her son got a shocking cancer diagnosis.

Nick and Melissa Thomas were on their way home from a cruise ship Aljaskom with their six kids when their oldest son, Marshall, began to feel sick.

The sixteen-year-old is diagnosed with mononucleosis prior to travel. She reportedly felt better after taking antibiotics.

But when the Thomases collapsed on Saturday in Denver to make their flight, he was so weak that he could hardly walk, according to Denver 7.

Marshall was taken to a hospital where he was diagnosed with leukemia, blood cancer.

"It's like in the fog." Just one foot in front of the other, Marshall's mother, Melissa, said to Denver 7. "She just feels unreal."

A week before the family went on vacation, Marshall was diagnosed with mononucleosis, also known as mono.

Doctors told his parents that it would be good if he took antibiotics.

Marshal's parents said they felt better, but felt again weak at the end of the journey.

"He's a pretty athletic boy, as strong as he is, he often does not bother," his father Nick television said.

Thomases flew to Denver on Saturday to regain flight to Suffolk, Virginia. Marshall barely walked when they landed.

"The stewardess has suggested that we look at it for immediate relief after landing," Melissa said.

The hospitals examined Marshall and recommended that they take him to Colorado Colorado's Aurora hospital.

There is a teenagers diagnosed acute lymphocytic leukemia B-cells (ALL).

ALL is cancer in which bone marrow produces too much immature white blood cells called lymphocytes.

They alternate with normal white blood cells, making it difficult for the body to fight the infection.

Symptoms include shortness of breath, mild bruising, frequent bleeding and chronic infections.

Since everyone attacks cells in the body that is fighting the infection, patients often develop inflammation of the throat, claims the Cleveland Clinic.

"Acute" means that the disease can rapidly spread in the body. This means early treatment, including chemotherapy and bone marrow transplantation, is crucial.

The American Cancer Society estimates that by 2019 almost 6,000 adults will get diagnosed with ALL, and will die about 1,500.

According to a closed Facebook group, a former nanny of Thomases, who lives in Denver, has taken over the family.

"You are leaving the country next week, so we need to find a place for our family," said Melissa Denver 7.

Physicians told Marshall's parents he must stay in Colorado for a month, but with 90 percent probability he will be cured.

However, over the past four days, Marshall is struggling with various health problems, including some infections.

"Physicians have given us a lot of hope, and everyone seems very confident, but apparently is not the way someone would want to fall," said Melissa Denver.

The family is now looking for donations to find a home in which she will remain while Marshall is going through treatment.
