Little is known about when West was diagnosed with this complex blood cancer. However, when his family shared with fans that West had passed away on June 9, 2017 at the age of 88, they described his battle with the disease as “short, but brave.” His passing was a huge shock to both fans and fellow Hollywood elite. His Batman co-star, Burt Ward, says West’s death was especially shocking to him considering he saw him just a few weeks before his passing.

“He was in great condition. In my heart, he had no idea [what was going to happen],” Ward told Fox News. “…From what I understand, on the flight back from our last weekend we worked together, he had some altitude sickness. He wanted to get that checked. The doctors said, 'You have a rise in white cell count' and they discovered he contracted leukemia, but it was in the early stages. A very mild, quiet stage. And they said, 'We're going to give you some pills and you'll be able to go home in a couple of days and you can live another 3-5 years or more.' That doesn't sound like someone who's going to immediately decease. It was a complete shock."

A few days after West’s passing, Los Angeles honored his incredible legacy by projecting the iconic bat signal on top of  City Hall. Additionally, West’s hometown of Walla Walla, Washington projected their own bat signal on the city’s landmark Whitman Tower.

What is Leukemia?

Leukemia is a type of blood cancer, but what makes this disease more complex is that there are different types of leukemia people may be diagnosed with. Leukemia is a cancer of the early cells in bone marrow that grow into white blood cells. Problems arise when your body starts making too many of these cells. Because the new cells are abnormal and don't work like they should, they're of little help in protecting you against infections.

Under the main header of leukemia are four main subtypes, which are broken down based on the maturity of the white blood cells they affect, and the type of cells from which they start. These subtypes include:

• Acute myeloid leukemia (AML)
• Chronic myeloid leukemia (CML)
• Acute lymphocytic leukemia (ALL)
• Chronic lymphocytic leukemia (CLL)

Acute leukemia happens when the cancer cells are rapidly dividing and the disease progresses quickly. Chronic leukemia is when most of the abnormal cells are mature, but they still don't work as well as healthy white blood cells. Myeloid leukemias start in myeloid cells, the type of cells that become white blood cells, red blood cells, or platelets. Lymphocytic leukemias start from the cells that produce lymphocytes.

Leukemia: Treatment

What makes leukemia even more of a complex cancer is that in some cases, this disease may not require any treatment at all. Instead of immediately opting for treatment, some people may be able to just partake in active surveillance so doctors can observe if the disease is spreading.

"This is a very different cancer," Dr. Nicole Lamanna, a hematologist/oncologist at Columbia University Medical Center, told SurvivorNet in a previous interview. "Most of the time, if you're diagnosed with cancer, we're going to treat you. Leukemia happens to be one of those cancers that you don't necessarily need treatment right away. Many patients are monitored even for years."

Deciding on active surveillance should be done in conjunction with your doctor, especially since this can often only refer to certain types of leukemia. The most common treatment for many blood cancers is by having a stem cell transplant (also called bone marrow transplant). If stem cell transplant is a part of your treatment plan, then before chemotherapy, your care providers may take some of your stem cells out and store them to use in the transplant later. (Or you may get stem cells from a donor.) After you complete chemotherapy, and your stem cells (and as a result, your immune system) have been wiped out, you will get new healthy stem cells put back in. It's basically like getting a brand new immune system.
