What Is Big Climb?

Why Blood Cancer?

Since 2000, more than 40% of cancer-fighting therapies approved by the FDA were first approved to treat blood cancer patients and many of these therapies are now helping patients with non-blood cancers. Some of the approved therapies are chemotherapy, bone and stem cell transplantation, and more recently immunotherapy.

Blood Cancer Statistics

An estimated 186,400 people in the US are expected to be diagnosed with leukemia, lymphoma or myeloma in 2021. Within the last ten years, blood cancer survival rates have doubled, tripled, or quadrupled depending on the specific cancer. An estimated 1,361,567 people in the US are either living with, or are in remission from, leukemia, lymphoma or myeloma.

Why Big Climb?

The Seattle Big Climb started in 1986 and has contributed to LLS generating over $26 million in funding for research. In 2018 the Seattle Big Climb broke the $3 million dollar barrier for a single year. Seattle is joined by ten other Big Climb events across the continental US.
