Final answer:
The Leukemia & Lymphoma Society focuses on combating blood cancers like leukemia and lymphoma. Leukemia involves an overproduction of leukocytes, while lymphoma involves malignant lymphocytes in the lymphatic system. Fundraisers are important for supporting research and treatment.
Step-by-step explanation:
The Leukemia & Lymphoma Society is a charity dedicated to fighting blood cancers, specifically leukemia and lymphoma. Leukemia is a type of cancer that involves an overproduction of leukocytes (white blood cells), affecting either the myeloid or lymphoid line of cells, which disrupts normal blood cell function. On the other hand, lymphoma, which is the most common type of blood cancer, directly involves the uncontrolled growth and accumulation of malignant T and/or B lymphocytes in parts of the lymphatic system such as lymph nodes, spleen, liver, and other tissues. Research and fundraising activities, such as bike rides, play a crucial role in supporting advances in treatment and potential cures for patients suffering from these conditions.
